  vaapi_encode: Move quality option to common code
  
  Use AVCodecContext.compression_level rather than a private option,
  replacing the H.264-specific quality option (which stays only for
  compatibility).
  
  This now works with the H.265 encoder in the i965 driver, as well as
  the existing cases with the H.264 encoder.

  avconv_hw: Add implicit device creation with default parameters
  
  If -hwaccel foo is supplied without any other device options, and the
  foo hwaccel is meant to have a device, try to make such a device with
  default parameters for the hwaccel to use.
