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. git-svn-id: svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm@374 af15c1b1-3010-417e-b628-4374ebc0bcbd
