Can the value of sample->buffer change?

I was going to yell (  :)  ), but I figure it might as well be kept
flexible, especially since the pointer to sample needs to be kept around
for other purposes, which means that it's easy enough to deference it
without too much acrobatics.

Once a Sound_DecodeAll() is done, it has no reason to change anymore, if
you're going to take that route, Andreas.

The alternative for the FLAC decoder is to keep a second internal buffer,
decode into that, and then memcpy to the actual internal->buffer, keeping
track of overflow, but that sounds less sane to me.
