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.

fc9bc08dca Indeo3: fix crashes on corrupt bitstreams. 
Splits at borders of cells are invalid, since it leaves one of the
cells with a width/height of zero. Also, propagate errors on buffer
allocation failures, so we don't continue decoding (which crashes).
