6f2e885f11 h264: fix end-of-stream conditions (flush). 
Decode pending data in the adapter prior to processing the actual
code for end-of-stream.

1c5c5ea9b8 h264: review and report errors accordingly. 
Use GST_ERROR() to report real errors instead of hiding them into
GST_DEBUG().

dde9232e10 h264: exclusively use GstAdapter, drop sub-buffer hack. 
Maintaining the sub-buffer is rather suboptimal especially since we
were also maintaining a GstAdapter. Now, we only use the GstAdapter
thus requiring minor extra parsing when receiving avcC buffers.

63e29adbf5 h264: fix slice_data_bit_offset calculation. 
Unlike what VA-API documentation defines, the slice_data_bit_offset
represents the offset to the first macroblock in the slice data, minus
any emulation prevention bytes in the slice_header().

This fix copes with binary-only VA drivers that won't be fixed any
time soon. Besides, this aligns with the current FFmpeg behaviour
that was based on those proprietary drivers implementing the API
incorrectly.

82dbd6f5be h264: complete any current picture decoder before SPS / PPS change. 
This ensures the VA context is clear when the encoded resolution
changes. i.e. make sure older picture is decoded with the older
VA context before it changes.

425060a7a8 h264: fix pred_weight_table() reconstruction. 
Only the explicit pred_weight_table(), possibly with the inferred default
values, shall be required. e.g. don't fill in the table if weighted_pred_flag
is not set for P/SP slices.
