• lavc : external hardware frame pool initialization

  lavc: external hardware frame pool initialization
  
  This adds a new API, which allows the API user to query the required
  AVHWFramesContext parameters. This also reduces code duplication across
  the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses
  the new API function. It takes care of initializing the hw_frames_ctx
  if needed, and does additional error handling and API usage checking.
  
  Support for VDA and Cuvid missing.

• qsv : Make the hevc idr_interval consistent with the h264 one

  qsv: Make the hevc idr_interval consistent with the h264 one
  
  According to the MediaSDK documentation the idr_interval value has
  a different meaning depending on the codec:
  
      0 in H264 means make every I-frame IDR, in HEVC it means to have
      it only at the beginning.
  
      1 in H264 means every other I-frame is not-IDR, in HEVC it means
      that every I-frame is IDR.
  
  Keep the behaviour consistent between the two encoders by increasing
  by 1 internally the idr_interval value for HEVC.
