f6866df0e6 - Made the maximum number of TiMidity voices configurable through the
timidity_voices cvar.
- Added stats lines for the OPL and Timidity MIDI devices.
- Completely changed the way TiMidity volume calculations are done. It
  should now be extremely close to the output a real GUS would produce with
  its official MIDI player (excepting where TiMidity normalizes sample
  volumes). The new equations more closely match what is specified by the DLS
  and SF2 specs (but not quite), so I presume it's also more musically
  correct than what TiMidity (and TiMidity++) do.

9450db3cec parameters. These seem to be used primarily to restrict percussion
instruments to specific notes.
- Changed note velocity to not use the volume curve in recompute_amp(), since
  this sounds closer to TiMidity++, although I don't believe it's correct
  MIDI behavior. Also changed expression so that it scales the channel volume
  before going through the curve.
- Reworked load_instrument to be less opaque.
- Went through the TiMidity code and removed pretty much all of the SDL_mixer
  extensions. The only exception would be kill_others(), which I reworked
  into a kill_key_group() function, which should be useful for DLS
  instruments in the future.

0d18580ff0 - Fixed: Timidity::Channel::mono, rpn, and nrpn were not initialized. In
particular, this meant that every channel was almost certainly in mono mode,
  which can sound pretty bad if the song isn't meant to be played that way.
- Added bank numbers to the MIDI precaching for Timidity, since I guess I do
  need to care about banks, if even the Duke MIDIs use various banks.
- Fixed: snd_midiprecache only exists in Win32 builds, so gameconfigfile.cpp
  shouldn't unconditionally link against it.
- Fixed: pre_resample() was still disabled, and it left two samples at the end
  of the new wave data uninitialized.

10c0d67b78 - Changed the MIDIStreamer to send the all notes off controller to each
channel when restarting the song, rather than emitting a single note off
  event which only has a 1 in 127 chance of being for a note that's playing
  on that channel. Then I decided it would probably be a good idea to reset
  all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
  (copied from the OPL player) improved its sound dramatically, so apparently
  Timidity has issues with short stream buffers. It's now at 1/2 sec in
  length. However, there seems to be something weird going on with
  corazonazul_ff6boss.mid near the beginning where it stops and immediately
  restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
  oscilloscopes and spectrums.
- Internal TiMidity now plays music.
- Changed the progdir global variable into an FString.
