Add device abstraction code for the UEFI Console and UEFI Shell-based file systems.

Make argv use narrow characters instead of wide characters.
Add setenv functionality.
Add poll() system call.
Change signal names into macros – required for standards compliance.  The enums were renamed and moved to sys/signal.h and the new macros reference the enums.
Added SIGBREAK, which is required for Python.
Modify stdio functions to fail cleanly when called with a NULL File Pointer argument.
Added <sys/cdefs.h> that just includes <sys/EfiCdefs.h>.  By adding this wrapper, we improve compatibility with *nix files which assume <sys/cdefs> exists.
Add <netdb.h>
Added macros for bcopy(), bcmp() and strsep().
Modify the clock() function so that it does not hang when running under an emulation environment such as NT32.
Move TM structure specific macros from the private tzfile.h into <time.h>
Add strncasecmp function.
Add strptime function.
Add gettimeofday function.
Add getcwd function.

+/** The wcsrtombs function converts a sequence of wide characters from the array

+    indirectly pointed to by src into a sequence of corresponding multibyte

+    characters that begins in the conversion state described by the object

+    pointed to by ps. If dst is not a null pointer, the converted characters

+    are then stored into the array pointed to by dst.  Conversion continues

+    up to and including a terminating null wide character, which is also

+    stored. Conversion stops earlier in two cases: when a wide character is

+    reached that does not correspond to a valid multibyte character, or

+    (if dst is not a null pointer) when the next multibyte character would

+    exceed the limit of len total bytes to be stored into the array pointed

+    to by dst. Each conversion takes place as if by a call to the wcrtomb

+    function.)

+

+    If dst is not a null pointer, the pointer object pointed to by src is

+    assigned either a null pointer (if conversion stopped due to reaching

+    a terminating null wide character) or the address just past the last wide

+    character converted (if any). If conversion stopped due to reaching a

+    terminating null wide character, the resulting state described is the

+    initial conversion state.

+

+    @Returns    If conversion stops because a wide character is reached that

+                does not correspond to a valid multibyte character, an

+                encoding error occurs: the wcsrtombs function stores the

+                value of the macro EILSEQ in errno and returns (size_t)(-1);

+                the conversion state is unspecified. Otherwise, it returns

+                the number of bytes in the resulting multibyte character

+                sequence, not including the terminating null character (if any).
