Subject: Move c/h files implementing/defining standard library stuff into a
 new libc directory, also standard'ify some parts of the code base (almost
 entirely #include fixes). This is to a) to cleanup firmware/common and
 firmware/include a bit, but also b) for Rockbox as an application which
 should use the host system's c library and headers, separating makes it easy
 to exclude our files from the build.

-FUNCTION
-        <<strcmp>>---character string compare
-        
-INDEX
-        strcmp
-
-ANSI_SYNOPSIS
-        #include <string.h>
-        int strcmp(const char *<[a]>, const char *<[b]>);
-
-TRAD_SYNOPSIS
-        #include <string.h>
-        int strcmp(<[a]>, <[b]>)
-        char *<[a]>;
-        char *<[b]>;
-
-DESCRIPTION
-        <<strcmp>> compares the string at <[a]> to
-        the string at <[b]>.
-
-RETURNS
-        If <<*<[a]>>> sorts lexicographically after <<*<[b]>>>,
-        <<strcmp>> returns a number greater than zero.  If the two
-        strings match, <<strcmp>> returns zero.  If <<*<[a]>>>
-        sorts lexicographically before <<*<[b]>>>, <<strcmp>> returns a
-        number less than zero.
-
-PORTABILITY
-<<strcmp>> is ANSI C.
-
-<<strcmp>> requires no supporting OS subroutines.
-
-QUICKREF
-        strcmp ansi pure
