Major MT-32 emu overhaul based on KingGuppy's code.

 o added configure option
 o mi2 intro doesn't freeze anymore and has no sound glitches
 o missing instruments in many titles are fixed
 o numerous memory overwrite bugs are fixed
 o code is cleaned a lot and splitted into many smaller files
 o mt32.cpp went to backends/midi
 o synced with upstream code
 o reverberation fixed

 * don't complain about File class wrapper :)
 * all custom types are back
 * #pragmas are to do
 * maybe some indentation is wrong too

I prefer smaller commits, but this thing came in one piece.
