GOB: Rewrite the AdLib players
This is a complete rewrite of the AdLib players for ADL and MDY/TBR
files in the Gob engine.
Major changes
1) The AdLib base class is now completely separated from all file
format code and can theoretically be used by any OPL2-based
format (within reason)
2) The new code is far better documented and more readable
3) The MDY player now actually works. The MDY/TBR format is
in reality the MUS/SND format created by AdLib as a simpler
alternative to the ROL format
4) Since the MAME emulator is quite buggy and leads to noticable
wrong percussion in the Gobliins 2 title music, the new AdLib
player will try to create a DOSBox OPL. If it's not compiled in,
or if the user configured opl_driver to "mame", it will print
out appropriate warnings.
