9aaadb1ee3 avutil/internal: Do not enable CHECKED with DEBUG
This avoids potential undefined behavior in debug mode while still allowing
developers which want to check for potential additional overflows to do so
by manually enabling this.

f125c54b7a 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().

785038c92c lavu: Adding ARIB STD-B67 (hybrid log-gamma) enum value and transfer function.
Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma)
based on the standardization in ARIB STD-B67:
http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf

The choice of enum value of 18 is consistent with HEVC:
http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481

And also with latest proposal for color format in mkv:
https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal

The implementation assumes a nominal input range of [0, 1], which is
consistent with HEVC.
