libpayload: Add PDCurses and ncurses' libform/libmenu

PDCurses provides an alternative implementation of the curses library
standard in addition to tinycurses.
Where tinycurses is really tiny, PDCurses is more complete and provides
virtually unlimited windows and the full API.
The PDCurses code is brought in "vanilla", with all local changes
residing in curses/pdcurses-backend/

In addition to a curses library, this change also provides libpanel (as
part of the PDCurses code), and libform and libmenu which were derived
from ncurses-5.9.
As they rely on ncurses internals (and PDCurses is not ncurses), more
changes were required for these libraries to work.

The build system is extended to install the right set of header files
depending on the selected curses implementation.

+PDCurses User's Guide
+=====================
+
+Curses Overview
+---------------
+
+The X/Open Curses Interface Definition describes a set of C-Language
+functions that provide screen-handling and updating, which are
+collectively known as the curses library.
+
+The curses library permits manipulation of data structures called
+windows which may be thought of as two-dimensional arrays of
+characters representing all or part of a terminal's screen.  The
+windows are manipulated using a procedural interface described
+elsewhere.  The curses package maintains a record of what characters
+are on the screen.  At the most basic level, manipulation is done with
+the routines move() and addch() which are used to "move" the curses
+around and add characters to the default window, stdscr, which
+represents the whole screen.
+
+An application may use these routines to add data to the window in any
+convenient order.  Once all data have been added, the routine
+refresh() is called.  The package then determines what changes have
+been made which affect the screen.  The screen contents are then
+changed to reflect those characters now in the window, using a
+sequence of operations optimized for the type of terminal in use. 
+
+At a higher level routines combining the actions of move() and addch()
+are defined, as are routines to add whole strings and to perform
+format conversions in the manner of printf(). 
+
+Interfaces are also defined to erase the entire window and to specify
+the attributes of individual characters in the window.  Attributes
+such as inverse video, underline and blink can be used on a
+per-character basis. 
+
+New windows can be created by allowing the application to build
+several images of the screen and display the appropriate one very
+quickly.  New windows are created using the routine newwin().  For
+each routine that manipulates the default window, stdscr, there is a
+corresponding routine prefixed with w to manipulate the contents of a
+specified window; for example, move() and wmove().  In fact, move(...)
+is functionally equivalent to wmove( stdscr, ...).  This is similar to
+the interface offered by printf(...) and fprintf(stdout, ...). 
+
+Windows do not have to correspond to the entire screen.  It is
+possible to create smaller windows, and also to indicate that the
+window is only partially visible on the screen.  Furthermore, large
+windows or pads, which are bigger than the actual screen size, may be
+created. 
+
+Interfaces are also defined to allow input character manipulation and
+to disable and enable many input attributes: character echo, single
+character input with or without signal processing (cbreak or raw
+modes), carriage returns mapping to newlines, screen scrolling, etc. 
+
+
+Data Types and the <curses.h> Header
+------------------------------------
+
+The data types supported by curses are described in this section.
+
+As the library supports a procedural interface to the data types, actual 
+structure contents are not described.  All curses data are manipulated 
+using the routines provided.
+
+
+THE <curses.h> HEADER
+
+The <curses.h> header defines various constants and declares the data 
+types that are available to the application.
+
+
+DATA TYPES
+
+The following data types are declared:
+
+	WINDOW *	pointer to screen representation
+	SCREEN *	pointer to terminal descriptor
+	bool		boolean data type
+	chtype		representation of a character in a window
+	cchar_t		the wide-character equivalent of chtype
+	attr_t		for WA_-style attributes
+
+The actual WINDOW and SCREEN objects used to store information are 
+created by the corresponding routines and a pointer to them is provided.  
+All manipulation is through that pointer.
+
+
+VARIABLES
+
+The following variables are defined:
+
+	LINES		number of lines on terminal screen
+	COLS		number of columns on terminal screen
+	stdscr		pointer to the default screen window    
+	curscr		pointer to the current screen image
+	SP		pointer to the current SCREEN struct
+	Mouse_status	status of the mouse
+	COLORS		number of colors available
+	COLOR_PAIRS	number of color pairs available
+	TABSIZE		size of one TAB block
+	acs_map[]	alternate character set map  
+	ttytype[]	terminal name/description    
+
+
+CONSTANTS
+
+The following constants are defined:
+
+GENERAL
+
+	FALSE		boolean false value
+	TRUE		boolean true value
+	NULL		zero pointer value
+	ERR		value returned on error condition
+	OK		value returned on successful completion
+
+VIDEO ATTRIBUTES
+
+Normally, attributes are a property of the character. 
+
+For chtype:
+
+	A_ALTCHARSET	use the alternate character set
+	A_BLINK		bright background or blinking
+	A_BOLD		bright foreground or bold
+	A_DIM		half bright -- no effect in PDCurses
+	A_INVIS		invisible
+	A_ITALIC	italic
+	A_LEFTLINE	line along the left edge
+	A_PROTECT 	protected (?) -- PDCurses renders this as a 
+			combination of the *LINE attributes
+	A_REVERSE	reverse video
+	A_RIGHTLINE	line along the right edge
+	A_STANDOUT	terminal's best highlighting mode
+	A_UNDERLINE	underline
+
+	A_ATTRIBUTES	bit-mask to extract attributes
+	A_CHARTEXT	bit-mask to extract a character
+	A_COLOR		bit-mask to extract a color-pair
+
+Not all attributes will work on all terminals. A_RIGHTLINE, A_LEFTLINE 
+and A_ITALIC are specific to PDCurses. A_INVIS and A_ITALIC are given 
+the same value in PDCurses.
+
+For attr_t:
+
+	WA_ALTCHARSET	same as A_ALTCHARSET
+	WA_BLINK	same as A_BLINK
+	WA_BOLD		same as A_BOLD
+	WA_DIM		same as A_DIM
+	WA_INVIS	same as A_INVIS
+	WA_LEFT		same as A_LEFTLINE
+	WA_PROTECT	same as A_PROTECT
+	WA_REVERSE	same as A_REVERSE
+	WA_RIGHT	same as A_RIGHTLINE
+	WA_STANDOUT	same as A_STANDOUT
+	WA_UNDERLINE	same as A_UNDERLINE
+
+Note that while A_LEFTLINE and A_RIGHTLINE are PDCurses-specific, 
+WA_LEFT and WA_RIGHT are standard. The following are also defined, for 
+compatibility, but currently have no effect in PDCurses: WA_HORIZONTAL, 
+WA_LOW, WA_TOP, WA_VERTICAL.
+
+THE ALTERNATE CHARACTER SET
+
+For use in chtypes and with related functions. These are a portable way 
+to represent graphics characters on different terminals.
+
+VT100-compatible symbols -- box characters:
+
+	ACS_ULCORNER	upper left box corner
+	ACS_LLCORNER	lower left box corner
+	ACS_URCORNER	upper right box corner
+	ACS_LRCORNER	lower right box corner
+	ACS_RTEE	right "T"
+	ACS_LTEE	left "T"
+	ACS_BTEE	bottom "T"
+	ACS_TTEE	top "T"
+	ACS_HLINE	horizontal line
+	ACS_VLINE	vertical line
+	ACS_PLUS	plus sign, cross, or four-corner piece
+
+VT100-compatible symbols -- other:
+
+	ACS_S1		scan line 1
+	ACS_S9		scan line 9
+	ACS_DIAMOND	diamond
+	ACS_CKBOARD	checkerboard -- 50% grey
+	ACS_DEGREE	degree symbol
+	ACS_PLMINUS	plus/minus sign
+	ACS_BULLET	bullet
+
+Teletype 5410v1 symbols -- these are defined in SysV curses, but
+are not well-supported by most terminals. Stick to VT100 characters
+for optimum portability:
+
+	ACS_LARROW	left arrow
+	ACS_RARROW	right arrow
+	ACS_DARROW	down arrow
+	ACS_UARROW	up arrow
+	ACS_BOARD	checkerboard -- lighter (less dense) than 
+			ACS_CKBOARD
+	ACS_LANTERN	lantern symbol
+	ACS_BLOCK	solid block
+
+That goes double for these -- undocumented SysV symbols. Don't use
+them:
+
+	ACS_S3		scan line 3
+	ACS_S7		scan line 7
+	ACS_LEQUAL	less than or equal
+	ACS_GEQUAL	greater than or equal
+	ACS_PI		pi
+	ACS_NEQUAL	not equal
+	ACS_STERLING	pounds sterling symbol
+
+Box character aliases:
+
+	ACS_BSSB	same as ACS_ULCORNER
+	ACS_SSBB	same as ACS_LLCORNER
+	ACS_BBSS	same as ACS_URCORNER
+	ACS_SBBS	same as ACS_LRCORNER
+	ACS_SBSS	same as ACS_RTEE
+	ACS_SSSB	same as ACS_LTEE
+	ACS_SSBS	same as ACS_BTEE
+	ACS_BSSS	same as ACS_TTEE
+	ACS_BSBS	same as ACS_HLINE
+	ACS_SBSB	same as ACS_VLINE
+	ACS_SSSS	same as ACS_PLUS
+
+For cchar_t and wide-character functions, WACS_ equivalents are also 
+defined.
+
+COLORS
+
+For use with init_pair(), color_set(), etc.:
+
+	COLOR_BLACK
+	COLOR_BLUE
+	COLOR_GREEN
+	COLOR_CYAN
+	COLOR_RED
+	COLOR_MAGENTA
+	COLOR_YELLOW
+	COLOR_WHITE
+
+Use these instead of numeric values. The definition of the colors 
+depends on the implementation of curses.
+
+

+testcurs demo to see what values are actually returned. The above are 
+just the keys required by X/Open. In particular, PDCurses defines many 
+CTL_ and ALT_ combinations; these are not portable.
+

+SDL Considerations
+==================
+
+There are no special requirements to use PDCurses for SDL -- all 
+PDCurses-compatible code should work fine. (In fact, you can even build 
+against the Win32 console pdcurses.dll, and then swap in the SDL 
+pdcurses.dll.) Nothing extra is needed beyond the base SDL library. 
+However, there are some optional special features, described here.
+
+The principal limitation of this port is that input is currently 
+restricted to ASCII (i.e., 0-127), plus the special keys like KEY_LEFT. 
+(You could have Unicode input, but then the input wouldn't match the 
+output, which is in Code Page 437.) Also, see the note about the 
+potential for incomplete output under "PDC_update_rects()", below.
+
+
+Fonts
+-----
+
+The font is a simple BMP, 32 characters wide by 8 characters tall, 
+preferably with a palette. (BMPs without palettes still work, but in 
+that case, no attributes will be available, nor will the cursor work.) 
+The first entry in the palette (usually black) is treated as the 
+background color; the last entry (usually white) is treated as the 
+foreground. These are changed or made transparent as appropriate; any 
+other colors in the palette are passed through unchanged. So -- although 
+a one-bit depth is sufficient for a normal font -- you could redraw some 
+characters as multi-colored tiles.
+
+The font must be monospaced. The size of each character is derived by 
+dividing the width of the BMP by 32 and the height by 8. There is no 
+constraint on the dimensions.
+
+As provided in the default font and expected by acs_map[], the font is 
+in Code Page 437 form. But you can of course use any layout if you're 
+not relying on correct values for the ACS_* macros.
+
+The font can be set via the environment variable PDC_FONT. If it's not 
+set, PDCurses looks for a file named "pdcfont.bmp" in the current 
+directory at the time of initscr(). If neither is found, it uses the 
+built-in default font encoded in deffont.h.
+
+
+Backgrounds
+-----------
+
+PDCurses for SDL supports an optional background image BMP. This is used 
+whenever start_color() has not been called (see the ptest demo for an 
+example), or when use_default_colors() has been called after 
+start_color(), and the background color of a pair has been set to -1 
+(see newdemo, worm, and rain for examples). The usage parallels that of 
+ncurses in an appropriate terminal (e.g., Gnome Terminal). The image is 
+tiled to cover the PDCurses window, and can be any size or depth.
+
+As with the font, you can point to a location for the background via the 
+environment variable PDC_BACKGROUND; "pdcback.bmp" is the fallback. 
+(There is no default background.)
+
+
+Icons
+-----
+
+The icon (used with SDL_WM_SetIcon() -- not used for the executable 
+file) can be set via the environment variable PDC_ICON, and falls back 
+to "pdcicon.bmp", and then to the built-in icon from deficon.h. The 
+built-in icon is the PDCurses logo, as seen in ../x11/little_icon.xbm. 
+The SDL docs say that the icon must be 32x32, at least for use with MS 
+Windows.
+
+If pdc_screen is preinitialized (see below), PDCurses does not attempt 
+to set the icon.
+
+
+Screen size
+-----------
+
+The default screen size is 80x25 characters (whatever size they may be), 
+but you can override this via the environment variables PDC_COLS and/or 
+PDC_LINES. (Some other ports use COLS and LINES; this is not done here 
+because those values are, or should be, those of the controlling 
+terminal, and PDCurses for SDL is independent of the terminal.) If 
+pdc_screen is preinitialized (see below), these are ignored.
+
+
+Integration with SDL
+--------------------
+
+If you want to go further, you can mix PDCurses and SDL functions. (Of 
+course this is extremely non-portable!) To aid you, there are several 
+external variables and functions specific to the SDL port; you could 
+include pdcsdl.h, or just add the declarations you need in your code:
+
+ PDCEX SDL_Surface *pdc_screen, *pdc_font, *pdc_icon, *pdc_back;
+ PDCEX int pdc_sheight, pdc_swidth, pdc_yoffset, pdc_xoffset;
+
+ void PDC_update_rects(void);
+ void PDC_retile(void);
+
+pdc_screen is the main surface, created by SDL_SetVideoMode(), unless 
+it's preset before initscr(). You can perform normal SDL operations on 
+this surface, but PDCurses won't respect them when it updates. (For 
+that, see PDC_retile().) As an alternative, you can preinitialize this 
+surface before calling initscr(). In that case, you can use pdc_sheight, 
+pdc_swidth, pdc_yoffset and/or pdc_xoffset (q.v.) to confine PDCurses to 
+only a specific area of the surface, reserving the rest for other SDL 
+operations. If you preinitialize pdc_screen, you'll have to close it 
+yourself; PDCurses will ignore resize events, and won't try to set the 
+icon. Also note that if you preinitialize pdc_screen, it need not be the 
+display surface.
+
+pdc_font, pdc_icon, and pdc_back are the SDL_surfaces for the font, 
+icon, and background, respectively. You can set any or all of them 
+before initscr(), and thus override any of the other ways to set them. 
+But note that pdc_icon will be ignored if pdc_screen is preset.
+
+pdc_sheight and pdc_swidth are the dimensions of the area of pdc_screen 
+to be used by PDCurses. You can preset them before initscr(); if either 
+is not set, it defaults to the full screen size minus the x or y offset, 
+as appropriate.
+
+pdc_xoffset and pdc_yoffset are the x and y offset for the area of 
+pdc_screen to be used by PDCurses. See the sdltest demo for an example.
+
+PDC_retile() makes a copy of pdc_screen, then tiles it with the 
+background image, if any. The resulting surface is used as the 
+background for transparent character cells. PDC_retile() is called from 
+initscr() and resize_term(). However, you can also use it at other 
+times, to take advantage of the way it copies pdc_screen: Draw some SDL 
+stuff; call PDC_retile(); do some curses stuff -- it will use whatever 
+was on pdc_screen as the background. Then you can erase the curses 
+screen, do some more SDL stuff, and call PDC_retile() again to make a 
+new background. (If you don't erase the curses screen, it will be 
+incorporated into the background when you call PDC_retile().) But this 
+only works if no background image is set.
+
+PDC_update_rects() is how the screen actually gets updated. For 
+performance reasons, when drawing, PDCurses for SDL maintains a table of 
+rectangles that need updating, and only updates (by calling this 
+function) during getch(), napms(), or when the table gets full. 
+Normally, this is sufficient; but if you're pausing in some way other 
+than by using napms(), and you're not doing keyboard checks, you may get 
+an incomplete update. If that happens, you can call PDC_update_rects() 
+manually.
+
+
+Interaction with stdio
+----------------------
+
+As with X11, it's a bad idea to mix curses and stdio calls. (In fact, 
+that's true for PDCurses on any platform; but especially these two, 
+which don't run under terminals.) Depending on how SDL is built, stdout 
+and stderr may be redirected to files.

+X11 Considerations
+==================
+
+PDCurses for X11 uses the System V IPC shared memory facility, along 
+with sockets, to share data between the curses program and the child 
+process created to manage the X stuff.
+
+When compiling your application, you need to include the <curses.h> or 
+<xcurses.h> that comes with PDCurses. You also need to link your code 
+with libXCurses. You may need to link with the following libraries under 
+X11R5:
+    Xaw Xmu Xt X11
+
+or, under X11R6:
+    Xaw Xmu Xt X11 SM ICE Xext
+
+You can run "xcurses-config --libs" to show the link parameters for your 
+system. If using dynamic linking, on some systems, "-lXCurses" suffices.
+
+By calling Xinitscr() rather than initscr(), you can pass your program 
+name and resource overrides to PDCurses. The program name is used as the 
+title of the X window, and for defining X resources specific to your 
+program.
+
+
+Interaction with stdio
+----------------------
+
+Be aware that curses programs that expect to have a normal tty 
+underneath them will be very disappointed! Output directed to stdout 
+will go to the xterm that invoked the PDCurses application, or to the 
+console if not invoked directly from an xterm. Similarly, stdin will 
+expect its input from the same place as stdout.
+

+
+		   The most useful action for KeyPress translations is 
+		   string(). The argument to the string() action can be 
+		   either a string or a hex representation of a 
+		   character; e.g., string(0x1b) will send the ASCII

+
+shmmin:		   On most systems, there are two Unix kernel parameters

+		   segment. These parameters are usually something like 
+		   SHMMIN and SHMMAX. To use shared memory, a program
+		   must allocate a segment of shared memory that is
+		   between these two values.  Usually these values are
+		   like 1 for SHMMIN and some large number for SHMMAX. 
+		   Sometimes the Unix kernel is configured to have a
+		   value of SHMMIN that is bigger than the size of one
+		   of the shared memory segments that libXCurses uses. 
+		   On these systems an error message like:
+
+		     Cannot allocate shared memory for SCREEN: Invalid argument
+
+		   will result. To overcome this problem, this resource 
+		   should be set to the kernel value for SHMMIN. This
+		   ensures that a shared memory segment will always be
+		   bigger than the kernel value for SHMMIN (and
+		   hopefully less than SHMMAX!)
+
+		   Default:	   0
+
+borderColor:	   The color of the border around the screen.
+		   Default:	   black
+
+borderWidth:	   The width in pixels of the border around the screen.
+		   Default:	   0
+
+clickPeriod:	   The period (in milliseconds) between a button 
+		   press and a button release that determines if a click
+		   of a button has occurred.
+		   Default:	   100
+
+doubleClickPeriod: The period (in milliseconds) between two button
+		   press events that determines if a double click
+		   of a button has occurred.
+		   Default:	   200
+
+composeKey:	   The name of the X key that defines the "compose key",
+		   which is used to enter characters in the Latin-1 
+		   character set above 0xA0. (See "Compose Keys for 
+		   Latin-1" below.) This is used only when PDCurses is 
+		   built without XIM support. While in compose mode, the 
+		   text cursor will appear as a hollow rectangle.
+		   Default:	   Multi_key
+
+
+Using Resources
+---------------
+
+All applications have a top-level class name of "XCurses". If Xinitscr() 
+is used, it sets an application's top-level widget name. (Otherwise the 
+name defaults to "PDCurses".)
+
+Examples for app-defaults or .Xdefaults:
+
+!
+! resources for XCurses class of programs
+!
+XCurses*lines:  30
+XCurses*cols:   80
+XCurses*normalFont:     9x13
+XCurses*bitmap: /tmp/xcurses.xbm
+XCurses*pointer: top_left_arrow
+!
+! resources for testcurs - XCurses
+!
+testcurs.colorRed:      orange
+testcurs.colorBlack:    midnightblue
+testcurs.lines: 25
+*testcurs.Translations: #override \n \
+  <Key>F12:  string(0x1b) string("[11~") \n
+!
+! resources for THE - XCurses
+!
+! resources with the * wildcard can be overridden by a parameter passed
+! to initscr()
+!
+the*normalFont: 9x15
+the*lines:      40
+the*cols:       86
+the*pointer:    xterm
+the*pointerForeColor: white
+the*pointerBackColor: black
+!
+! resources with the . format can not be overridden by a parameter passed
+! to Xinitscr()
+!
+the.bitmap:     /home/mark/the/the64.xbm
+the.pixmap:     /home/mark/the/the64.xpm
+
+Resources may also be passed as parameters to the Xinitscr() function. 
+Parameters are strings in the form of switches; e.g., to set the color 
+"red" to "indianred", and the number of lines to 30, the string passed 
+to Xinitscr would be: "-colorRed indianred -lines 30"
+
+
+Compose Keys for Latin-1
+------------------------
+
+When built without XIM support, PDCurses for X11 provides its own, 
+limited compose key system for Latin-1 characters. The available 
+combinations are listed here. For a given character, any of the 
+combinations shown in the last column may be used. To generate a 
+character, press the "compose" key followed by one of the pairs of 
+keystrokes. Where no key is evident, the spacebar is used.  Thus, to 
+generate the NO-BREAK SPACE, press the "compose" key followed by two 
+hits of the spacebar.
+
+With a typical modern X server, you can get many more compose key 
+combinations by using XIM instead. Configure PDCurses with --enable-xim 
+to use XIM support.

+Deprecated
+----------
+
+XCursesProgramName is no longer used. To set the program name, you must 
+use Xinitscr(), or PDC_set_title() to set just the window title.
+
+The XCursesExit() function is now called automatically via atexit(). 
+(Multiple calls to it are OK, so you don't need to remove it if you've 
+already added it for previous versions of PDCurses.)
+
+XCURSES is no longer defined automatically, but need not be defined, 
+unless you want the X11-specific prototypes. (Normal curses programs 
+won't need it.)
