quakespasm/Quake/gl_vidnt.c
Ozkan Sezer cbb7eb0428 Backported external music files support using decoder libraries and the 
new raw samples interface from Hammer of Thyrion (uhexen2) :
- bgmusic.c, bgmusic.h: New BGM interface for background music handling.
  Handles streaming music as raw sound samples.
- bgmnull.c: BGM source for cases where the engine is configured for no
  sound.
- cl_main.c: Include bgmusic.h. Call BGM_Stop() and CDAudio_Stop() in
  CL_Disconnect().
- cd_sdl.c: Moved bgmvolume boundary checking to bgmusic.c upon value
  changes.
- gl_vidnt.c, gl_vidsdl.c, cl_parse.c: Include bgmusic.h. Add BGM_Pause()
  and BGM_Resume() calls along with CDAudio_ counterparts.
- cl_parse.c: Replace CDAudio_Play() call by the new BGM_PlayCDtrack()
  which first tries CDAudio_Play() and then streaming music if it fails.
- host.c: Include bgmusic.h. Call BGM_Update() just before S_Update()
  in Host_Frame(). In Host_Init(), call BGM_Init() after other audio init
  calls. In Host_Shutdown(), call BGM_Shutdown() before all other audio
  shutdown calls.
- snd_dma.c: Include snd_codec.h and bgmusic.h. Call S_CodecInit() from
  S_Init(). Call S_CodecShutdown() from S_Shutdown().
- snd_codec.c, snd_codec.h: New public codec interface for streaming
  music as raw samples. Adapted from quake2 and ioquake3 with changes.
  Individual codecs are responsible for handling any necessary byte swap
  operations.
- snd_codeci.h: New header for snd_codec internals.
- snd_wave.c, snd_wave.h: Codec for WAV format streaming music. Adapted
  from ioquake3 with changes.
- snd_vorbis.c, snd_vorbis.h: Codec for Ogg/Vorbis format streaming music.
- snd_mp3.c, snd_mp3.h: Codec for MP3 format streaming music using libmad.
  Adapted from the SoX project with changes.
- Makefile: Adjusted for the new sources. Added switches USE_CODEC_WAVE,
  USE_CODEC_MP3, USE_CODEC_VORBIS for enabling and disabling individual
  codecs.
- Windows makefiles and project files as well as other CodeBlocks project
  files will be updated shortly.
