mp3lib: drop internal mp3lib tree

Delete mp3lib which has been the default mp3 decoder until now. In
addition to being an unnecessary embedded library it now fails to
compile correctly with the new gcc-4.6, producing noise.

After the deletion the default decoder priority for mp3 will be first
libmpg123 (a newer version of the code that mp3lib was based on) if
available, then ffmp3float which should be available in all normal
compiles. I think that some tweaking may be required as these decoder
alternatives get wider testing, but any problems should be solvable
and there should be no need for mp3lib.

-* mpg123_synth_1to1 works the same way as the c version of this
-* file.  only two types of changes have been made:
-* - reordered floating point instructions to
-*   prevent pipline stalls
-* - made WRITE_SAMPLE use integer instead of
-*   (slower) floating point
-* all kinds of x86 processors should benefit from these
-* modifications.
-*
-* useful sources of information on optimizing x86 code include:
