Subject: do not merge: The qcom video decoders always output yuv data after
 adjusting dimensions to be a multiple of 16.

Add a quirk mode to OMXCodec that makes it aware of this fact for proper display. Also integrate back a change from eclair-mr2 that delays releasing an output buffer briefly after posting it to surface flinger, as we don't know how long it'll take it to actually display the buffer's content.
