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.
