cc86bd4ccc proresenc: Don't free a buffer not owned by the codec
The data in coded_frame isn't allocated using get_buffer, but
is copied from the input frame to the encoder, so we should
not try to free it ourselves.

This fixes an assert failure when running in debug mode.

6d9e74cd41 proresenc: Write the full value in one put_bits call
Previously, the put_bits call writing the value wrote a value
larger than the number of bits specified, failing asserts
in debug mode. There was no actual bitstream writer corruption,
since the overwritten bit already always was set to 1.

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.

This allows user to select quantisation matrix from different profile,
stamp frames with custom vendor string and change target bitrate.

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.

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.

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.
