b5696ff2b8 prores: use natural integer type for the codebook index 
The operations that use it require it to be promoted to a larger (natural)
type and thus perform sign extension on it.

While an optimal compiler may account for this, gcc 4.6 (for x86 Windows)
fails. Using the natural integer type provides a 2% speedup for Win64
and 1% for Win32.

3ab9a2a557 rv34: change most "int stride" into "ptrdiff_t stride". 
This prevents having to sign-extend on 64-bit systems with 32-bit ints,
such as x86-64. Also fixes crashes on systems where we don't do it and
arguments are not in registers, such as Win64 for all weight functions.

3ec623c22f prores: fix multithreaded decoding case when slice quantisers are not the same 
Since quantisation matrices are stored in context, decoding slices with
different quantisers in parallel leads to unpredictable content of
aforementioned matrices and wrong output picture thereof.
