Randy Heit 2b721975dd VERY IMPORTANT NOTE FOR ANYBODY BUILDING FROM THE TRUNK: This commit adds support
for FMOD Ex while at the same time removing support for FMOD 3. Be sure to update
your SDKs. GCC users, be sure to do a "make cleandep && make clean" before
building, or you will likely get inexplicable errors.

- Fixed: If you wanted to make cleandep with MinGW, you had to specifically
  specify Makefile.mingw as the makefile to use.
- Added a normalizer to the OPL synth. It helped bring up the volume a little,
  but not nearly as much as I would have liked.
- Removed MIDI Mapper references. It doesn't work with the stream API, and
  it doesn't really exist on NT kernels, either.
- Reworked music volume: Except for MIDI, all music volume is controlled
  through GSnd and not at the individual song level.
- Removed the mididevice global variable.
- Removed snd_midivolume. Now that all music uses a linear volume scale,
  there's no need for two separate music volume controls.
- Increased snd_samplerate default up to 48000.
- Added snd_format, defaulting to "PCM-16".
- Added snd_speakermode, defaulting to "Auto".
- Replaced snd_fpu with snd_resampler, defaulting to "Linear".
- Bumped the snd_channels default up from a pitiful 12 to 32.
- Changed snd_3d default to true. The new cvar snd_hw3d determines if
  hardware 3D support is used and default to false.
- Removed the libFLAC source, since FMOD Ex has native FLAC support.
- Removed the altsound code, since it was terribly gimped in comparison to
  the FMOD code. It's original purpose was to have been as a springboard for
  writing a non-FMOD sound system for Unix-y systems, but that never
  happened.
- Finished preliminary FMOD Ex support.
