Started work on OSX/Linux SP; jagame builds on OSX
Loads more work on SP SDL; still doesn't link, needs a lot of cleaning up...
some merges
Couple of fixes for clang

Though there are still some errors with clang, i decided just to switch
to llvm/gcc
SDL SP nearly links on OSX!
ack this is a hideous mess

intending to redo this again...
carrying on through the pain
Merge branch 'sdl' into sdl_sp
Merge remote-tracking branch 'upstream/master' into sdl_sp
Merge branch 'sdl' into sdl_sp
Fixed Q_vsnprintf; starting to cleanup for merge into proper sdl branch
put jpeg-6 back for now for easier merge...
reverted zlib->zlib32 for easier merge
further cleanup; reverting unwanted file changes for merge
More cleanup; seems to actually build again
Many, many, many case fixes for linux; need to sort out some of the zlib32 assembly still
SP now actually works on linux

disabled inflate_fast; temporary fix until zlib32 replaced w/ zlib
Merge branch 'sdl' into sdl_sp
Merge branch 'sdl' into sdl_sp
Merge branch 'sdl' into sdl_sp
