OpenAL

[BlackAura]

I've been working on an OpenAL sound system for Quake 3, and I'm at the stage 
where everything appears to work correctly.

I have a preliminary patch available for testing (Linux only) from here:

http://files.frashii.com/~sp00nz/Doom/files/BlackAura/q3_openal_icculus.diff

It contains an OpenAL sound system which entirely replaces the existing sound 
system. It also adds support for Ogg Vorbis music and sound effects in both 
the OpenAL and original sound systems, using a separate sound decoder system.

It should be portable to other systems, except for the part that loads the 
OpenAL library at runtime (unix/linux_qal.c). That can be disabled by 
defining OPENAL_STATIC, and including the appropriate libraries.
