cf888edf81 Removed most of the incomplete legacy FM OPL emulation part of the SB16. 
Only keep the OPL timer code required for chip detection. Started implementing
save/restore support in the OPL3 code ported from DOSBox.

fb265dc532 Ported OPL3 emulation from DOSBox. 
The code currently only works with the SDL sound output module and at 44100 Hz,
with 16 bit stereo signed little endian format. FM volume control and
save/restore support are not implemented yet. The legacy code for generating
MIDI notes still works and will be removed when mixing support is implemented
in all sound modules.
