tidy-ups in FS* stdio replacement functions. add new FS_filelength.
snd codec layer updates: changed codec_open() to operate only on a
stream pointer and moved all file open/close stuff to snd_codec.c.
codec_open now only returns true or false upon success or failure
instead of a stream pointer. added new snd_codec.c toplevel helper
S_CodecForwardStream(), which allows one codec to hand over its
stream from its codec_open() to another codec. Support for tracker
(mod) music, including support for Unreal umx containers. (might
be useful if we ever make a Nehahra version of the engine some day.
edit the makefiles to enable when compiling.)

and add a new blocksize field to it which the flac decoder can
use. updated decoder sources for the snd_info_t changes, where
I made minor tidy-ups too, tightening several format checks and
fixing a few gotchas in snd_wave.c and snd_mem.c.
* snd_flac.c: adjusted for snd_info_t changes. no longed storing
metadata->data.stream_info in our private data, but just storing
a pointer to the stream->info structure. No longer checking the
metadata total_samples field (the FLAC__StreamMetadata_StreamInfo
doesn't seem to have any alignment or pack attributes and I don't
safe with its offset across different compilers), but added check
to make sure that we hit and parsed a STREAMINFO metadata instead,
and our new state seems just fine for validating the file.

* updated copyright years for several sound related sources.

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.
