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

* ----------------------------------------------------------------------Stepan Moskovchenko2006-05-01
| | | | | | | | | | | | Added Karl Kurbjun's sound output patch, cleaned up some output. Main file is now midiplay.c, midi2wav is still in there for anyone who wants it. Set sampling rate to 22k, and increased note decay time. Reduced number of concurrent active voices and made new notes replace used voices if none are available. This makes lag less apparent. I really hope this wont go red. (turns around and runs) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9858 a1c6a512-1295-4272-9138-f99709370657
