huffyuvenc: add a non-deterministic option

Not actually used in huffyuvenc, but rather in setting the frame
threading.

Example for some files:
context=0:       851974   27226   1137281
context=1,ND=0:  471819   22604    972351

avcodec/proresenc_kostya: set initial max_slice_size based on frame_size_upper_bound

If the initial max_slice_size is 0 then reallocation is disabled for the first
slice.

wavpackenc: proper buffer allocation

The allocation didn't account for headers, that can be easily 79 bytes.
As a result, buffers allocated for a few samples (e.g. 5 in the original
bug) could be undersized.

Fixed ticket #2881.
