* open music stream in S_AL_StartBackgroundTrack() instead of relying
on S_AL_MusicProcess() to open it. This allows S_AL_MusicProcess() to
return early when called whenever there is no open music stream to prevent
a segfault.
* adds a shell script ./make-macosx-ub.sh that builds Mac OS X Universal Binary
* fixes Mac OS X x86 VM crashes (-mstackrealign)
* adds current working directory to the search path on Mac OS X to make
working with .app bundles easier
* various tweaks to make ioquake3 build against the 10.2 SDK
* changed default OpenAL .dylib location to the path of the one included with
the Framework bundled in 10.4 (for USE_OPENAL_DLOPEN)
* updated to a Universal libSDL-1.2.0.dylib
would fight for a source and you'd get a horrible distorted sound that was
each of the two sounds interleaved
* Changed the default of s_alPrecache to 1 -- having it off seems to cause
problems for some and it doesn't actually improve things much
* Changed a few of the variable names in snd_openal.c to be more sane
* Remove -gfull from linux section in Makefile -- it's darwin only
* Cast away some warnings that surfaced from using "new" AL headers
* Various whitespace and consistency fixes
+ An abstract codec system, simplifying support for new formats
+ Changes versus BlackAura's patch:
o Consolidated the OpenAL parts into one file
o Changed the function naming scheme to more closely resemble Q3
o Changed the interface to fall back on the "base" sound system
if loading OpenAL fails
+ This is enabled on Linux and MinGW for now, but should work on the
other *nixs with appropriate additions to the Makefile
+ NOT enabled on OS X or MSVC Windows builds
+ Probably breaks the Windows build again
* Retabulated sdl_snd.c and made the messages less verbose since
there do not seem to be many having problems with SDL sound now
