Backport of Sound_DecodeAll() from development branch

I was previously using SDL_sound for audio decoding in my apps and simply used Sound_DecodeAll() for the job.  That meant I could calculate the duration easily.  This was a horrible memory waster though (playing a few layered tracks simultaneously would eat up anywhere between 100 and 300MB RAM.)

So I switched to Sound_Decode().  However, being able to tell the duration of the sample is critical.  Since SDL_sound might need some time for a proper release, I ported Sound_DecodeAll() from the development branch to the stable-1.0 branch.  It's a backport of these:

  http://hg.icculus.org/icculus/SDL_sound/rev/c66080364dff
  http://hg.icculus.org/icculus/SDL_sound/rev/3e705c9180e5

Note that binary compatibility with SDL_sound 1.0 is preserved.
