0f01602362 SVQ3: Allow decoding if thread_count is > 1 
svq3 still doesn't support multithreading, but it's simpler for clients if
they can enable threading for all codecs by default.

793bbf9544 Split out setting of bit allocation parameters to a separate function. 
Th new function only needs to be called at initialization because bit
allocation parameters currently do not change during encoding.

successive blocks rather than copying.
