With the new decode API, doing this in ffmpeg.c is impractical. There
was resistance against removing the warning, so put it into libavcodec.

Not bothering with reducing the warning to verbose log level for
subsequent wanrings. The warning should be rare, and only happen when
developing new codecs for the old API.

Includes a change suggested by Michael Niedermayer.

  lavfi: add a QSV scaling filter

This is a noop since it depends on sharing a hwcontext with the
decoder/encoder, see 04b17ff9 and 130e1f1dMerged-by: Hendrik Leppkes <h.leppkes@gmail.com>

* commit 'ad9c9440':
  qsvenc: support getting the session from an AVHWFramesContext

This commit is a noop, as it needs to be fully re-implemented for our
qsv components.

This way, in case of bit rate not being set, max_bitrate will be
used instead. This enables, for example, re-using max_bitrate
information from the input or doing transcoding with a rate
control mode that is not bit rate based.
