VERY IMPORTANT NOTE FOR ANYBODY BUILDING FROM THE TRUNK: This commit adds support

Browse source 
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.

* \brief
* This module describes the decoder layers provided by libFLAC++.
*
* The libFLAC++ decoder classes are object wrappers around their
* counterparts in libFLAC. All decoding layers available in
* libFLAC are also provided here. The interface is very similar;
* make sure to read the \link flac_decoder libFLAC decoder module \endlink.
*
* There are only two significant differences here. First, instead of
* passing in C function pointers for callbacks, you inherit from the
* decoder class and provide implementations for the callbacks in your
* derived class; because of this there is no need for a 'client_data'
* property.
*
* Second, there are two stream decoder classes. FLAC::Decoder::Stream
* is used for the same cases that FLAC__stream_decoder_init_stream() /
* FLAC__stream_decoder_init_ogg_stream() are used, and FLAC::Decoder::File
* is used for the same cases that
* FLAC__stream_decoder_init_FILE() and FLAC__stream_decoder_init_file() /
* FLAC__stream_decoder_init_ogg_FILE() and FLAC__stream_decoder_init_ogg_file()
* are used.

* The usage of this class is similar to FLAC__StreamDecoder,
* except instead of providing callbacks to
* FLAC__stream_decoder_init*_stream(), you will inherit from this
* class and override the virtual callback functions with your
* own implementations, then call init() or init_ogg(). The rest
* of the calls work the same as in the C layer.
*
* Only the read, write, and error callbacks are mandatory. The
* others are optional; this class provides default
* implementations that do nothing. In order for seeking to work
* you must overide seek_callback(), tell_callback(),
* length_callback(), and eof_callback().

This is not the complete FLAC distribution. It contains only what
ZDoom needs to decode compressed FLAC streams. For the complete
distribution, please visit <http://flac.sourceforge.net/>. The
version here is currently version 1.2.1.
Of course, under Linux, you are encouraged to ignore this source

* This code implements the MD5 message-digest algorithm.
* The algorithm is due to Ron Rivest. This code was
* written by Colin Plumb in 1993, no copyright is claimed.
* This code is in the public domain; do with it what you wish.
*
* Equivalent code is available from RSA Data Security, Inc.
* This code has been tested against that, and is equivalent,
* except that you don't need to include two pages of legalese
* with every copy.
*
* To compute the message digest of a chunk of bytes, declare an
* MD5Context structure, pass it to MD5Init, call MD5Update as
* needed on buffers full of bytes, and then call MD5Final, which
* will fill a supplied 16-byte array with the digest.
*
* Changed so as no longer to depend on Colin Plumb's `usual.h' header
* definitions; now uses stuff from dpkg's config.h.
* - Ian Jackson <ijackson@nyx.cs.du.edu>.
* Still in the public domain.
*
* Josh Coalson: made some changes to integrate with libFLAC.
* Still in the public domain.

March 8, 2008
- 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.
- Added back support for custom streams.
March 7, 2008
- I think the new FMOD Ex code should support everything the old FMOD 3 code
did, sans custom streaming sounds.
- 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.
March 6, 2008
- Fixed: If P_BounceWall() can't find a wall when it does its trace, but it
was entered because a line blocked the projectile, then it should still use
