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.

-   A C-program for MT19937, with initialization improved 2002/2/10.
-   Coded by Takuji Nishimura and Makoto Matsumoto.
-   This is a faster version by taking Shawn Cokus's optimization,
-   Matthe Bellew's simplification.
-
-   Before using, initialize the state by using srand(seed).
