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.
