  configure: Move x86 assembler sanity check into assembler probe function
  
  This allows for more graceful fallback from NASM to Yasm if the available
  NASM version is too old.

• avutil/hwcontext_dxva2 : Don’t improperly free IDirect3DSurface9 objects

  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().

  h264_sei: Add namespace prefix to all SEI values
  
  This avoids confusion with equivalent H.265 SEI values when both are
  being used at the same time.
