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).

9806b9ab5c Revert "Don't use expressions with side effects in macro parameters" 
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.
