- Updates from my code in SDL_mixer:
- Fix APE header presence detection: APEv2 doesn't guarantee header.
We rely on bit31 of the flags field of the header/footer, instead.
- Add code to skip Lyrics3 v1 / v2 tags.
- Remove the non-standard 'Extended ID3v1' tag support: None of the
significant libraries like getID3, taglib or libid3tag support it.
Not supported in most, if not all mp3 players, either.
- The 'APE before ID3v1' was duplicated code because we removed the
TAG+ support: removed it.
- Add a FIXME note about handling possible double-ID3v1 tags.
- Add a FIXME note about order of tags at the end of the file.
- A few minor tidy-ups.

( also see: https://bugzilla.libsdl.org/show_bug.cgi?id=4728 )
Instead of doing it 'as-we-go' every time, skip the tags at file-open
time only once.
The former implementation had the chance of not having the full tag in
the frame, that includes a possibility of even not having the complete
tag magic in the frame leading to not identifying a tag.
The new implementation skips all the tags at file-start and file-end,
and does that only once.
Also added are detection and skipping of extended ID3v1 and APEv1 tags.

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.)

doesn't include the leading dot for the extension, nor does it ever return
NULL.

removed the inline versions which only handled integers. moved CLAMP
macro to common.h. Adjusted all places for the renamed macros.

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.
