Mans Rullgard 1c2c64edac proresenc: make a variable local to the loop where it is used 
This moves the mbs_per_slice declaration inside the only loop
where it is used.  Fixes a dead assignment.

Kostya Shishkov 4db4b53dc8 proresenc: give user a possibility to alter some encoding parameters 
This allows user to select quantisation matrix from different profile,
stamp frames with custom vendor string and change target bitrate.

Kostya Shishkov 235d693286 prores: handle 444 chroma in right order 
ProRes codes chroma blocks in 444 mode in different order than luma blocks,
so make both decoder and encoder read/write chroma blocks in right order.

Christophe GISQUET 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.

Kostya Shishkov 6d702dc072 proresenc: force bitrate not to exceed given limit 
Apple ProRes Format Specifications mentions target data size for every frame,
so make sure frame meets it. This also allows encoder to demand much smaller
packet sizes for output.
