[sdlsound] Mechanism of getting buffer seperate from Sound_Sample?

It is bad form, but (at least currently) it works, since we use malloc
to allocate the buffer. Don't know a good solution. If you're wrapping the
buffer in a memory RWops, you can always use the trick we use for SMPEG
(The Reference Counter RWops, look at extra_rwops.h in SDL_sound's
basedir...).
