* OpenAL support, from BlackAura aka Stuart Dalton <badcdev@gmail.com>

Browse source 
+ 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

<TTimo> some shitty mess with DMA buffers

<TTimo> some other systems would not let you mmap the DMA with read permissions
