Subject: Finally commit Metadata on Buffer! buffering.c and buffering.h
 implement the new buffering API. playback.c is translated to that API. For
 more information about the whole concept, see
 http://www.rockbox.org/wiki/MetadataOnBuffer. There should be no major
 visible changes, but most existing bugs remain (though fixing them should be
 easier now that playback.c is a bit less complex) and there probably will be
 new ones. Please report any problem! Next step is to adapt cuesheet support,
 which is partly disabled here, and of course fix as much bugs as possible.
