h264: allow cropping to AVCodecContext.width/height
...
Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.
This is required for correct cropping of MOV files from Canon cameras.

iac: generate codec tables as they are supposed to be
...
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.
Many thanks to Maxim Poliakovsky for providing all needed information
for this.

mpc8: fix maximum bands handling

In Musepack SV8 codec property tell the maximum nonzero band, but every

In hybrid frames long window part ends at 36 samples for most of the cases

samples, which caused wrong bitstream decoding for such blocks.
