avcodec/hevc_sei: fix amount of bits skipped when reading picture timing SEI message
...
The code was skipping the entire reported SEI message size regardless of
the amount of bits read.
While in theory safe for NALU where the picture timing SEI message is alone
or at the end as we're using the checked bitstream reader, it isn't in any
other situation, where every SEI message in the NALU after the picture
timing one would potentially fail to parse.

avutil/hwcontext_dxva2: Don't improperly free IDirect3DSurface9 objects
...
Add dxva2_pool_release_dummy() and use it in call to
av_buffer_create() in dxva2_pool_alloc().
Prior to this change, av_buffer_create() was called with NULL for the
third argument, which indicates that av_buffer_default_free() should
be used to free the buffer's data. Eventually, it gets to
buffer_pool_free() and calls buf->free() on a surface object (which is
av_buffer_default_free()).
This can result in a crash when the debug version of the C-runtime is
used on Windows. While it doesn't appear to result in a crash when
the release version of the C-runtime is used on Windows, it likely
results in memory corruption, since av_free() is being called on
memory that was allocated using
IDirectXVideoAccelerationService::CreateSurface().
