* Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz2010-05-06
| | | | | | | | 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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657

Probably not a good idea for speed, but the order can be optimized more later. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15652 a1c6a512-1295-4272-9138-f99709370657
