796dca027b alac: do not return success if nothing was decoded 
If we encounter an END element before anything is decoded, we would
return success even though the output frame has not been allocated,
which is invalid.

bc6e0b64a9 vp9: split last/cur_frame from the reference buffers. 
We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.

This prepares the decoder for frame threading support.

04763c6f87 h264_direct: use the reference mask from the actual reference 
Not from the underlying frame. Fixes races with frame threading in
field-coded files, where decoding would wait for the wrong field (e.g.
random failures in mixed-nal-coding).

This reverts commit 25bacd0a0c32ae682e6f411b1ac9020aeaabca72.

Since 230b1c070, the bytewise AV_W*() macros only expand their
argument once, so revert to the more readable version of these.

25bacd0a0c Don't use expressions with side effects in macro parameters 
AV_WB32 can be implemented as a macro that expands its parameters
multiple times (in case AV_HAVE_FAST_UNALIGNED isn't set and the
compiler doesn't support GCC attributes); make sure not to read
multiple times from the source in this case.
