by COM_FileGetExtension. Adjusted all users because COM_FileGetExtension
doesn't include the leading dot for the extension, nor does it ever return
NULL.

DEFAULT_SOUND_PACKET_VOLUME and DEFAULT_SOUND_PACKET_ATTENUATION
from sound.h to protocol.h. remove unused gamealive, soundalive
and splitbuffer members from the dma_t structure. make SNDDMA_Init()
to take a dma_t* parameter and make sn static to snd_dma.c. copy
over LordHavoc's S_StartSound skip calculation fixes from uhexen2.
make many functions/data static to their respective files. many
whitespace/formatting clean-ups.

* snd_mix.c: Increased PAINTBUFFER_SIZE from 512 to 2048.
* snd_mix.c: snd_vol is static now. it is calculated in S_PaintChannels and
only used in SND_PaintChannelFrom16. all its other uses are removed from
Snd_WriteLinearBlastStereo16, S_TransferStereo16, S_TransferPaintBuffer.
The way it was, the sound volume was applied to the whole final contents
of the paint buffer, but with this new quake2+ way we can add raw samples
to the paint buffer with its own volume, such as bgmvolume. However, this
makes the snd_scaletable to be recalculated everytime the sfxvolume is,
changed, therefore it is adjusted that way to incorporate sfxvolume.
* snd_mix.c: In S_PaintChannels, check against s_rawend and copy from the
streaming sound source if necessary.
* snd_dma.c: Added old_volume to detect sfxvolume changes. Made S_Update to
compare it to sfxvolume.value and call SND_InitScaletable() if it changed.
* snd_dma.c: Add new globals s_rawsamples and s_rawend. Reset s_rawend to 0
in S_ClearBuffer. Add new function S_RawSamples, adapted from quake2 with
its 8 bit stereo playback fixed.
* snd_dma.c (S_FileExtension): Add new function which returns the given
sound file's extension including the dot, or NULL.
* q_sound.h: Add new macro MAX_RAW_SAMPLES, defined as 8192. Add externs
for new globals s_rawsamples and s_rawend. Add prototype for the new
S_RawSamples and S_FileExtension functions.

* q_sound.h: add WAV_FORMAT_PCM as a new macro, defined as 1.
* snd_mem.c (S_LoadSound): use WAV_FORMAT_PCM. reject wav files which are
neither 8 nor 16 bit. reject wav files which have zero samples. report
the wav file name with the error messages so that they mean something.
