Use buflib for the allocation of voice PCM resources.

Browse source 
Buffers are not allocated and thread is not created until the first
call where voice is required.

Adds a different callback (sync_callback) to buflib so that other
sorts of synchonization are possible, such as briefly locking-out the
PCM callback for a buffer move. It's sort of a messy addition but it
is needed so voice decoding won't have to be stopped when its buffer
is moved.
