All these commits are cherry-picks from FFmpeg. Maybe some slight
differences sneaked in but the Libav codebase still differs too much
with our own to make a proper diff. This merge is a noop.

  lavu: remove the custom atomic API

This commit is a noop. The removal is postponed until all usages in
FFmpeg are dropped as well. A patchset is on discussion on the
mailing-list:
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-March/209003.htmlMerged-by: Clément Bœsch <u@pkh.me>

This supports retrieving the device from a provided hw_frames_ctx, and
automatically creating a hw_frames_ctx if hw_device_ctx is set.

The old API is not deprecated yet. The user can still use
av_vdpau_bind_context() (with or without setting hw_frames_ctx), or use
the API before that by allocating and setting hwaccel_context manually.

Cherry-picked from Libav commit 1a7ddba5.
(Adds missing APIchanges entry to the Libav version.)
Reviewed-by: Mark Thompson <sw@jkqxz.net>

This "reuses" the flags introduced for the av_vdpau_bind_context() API
function, and makes them available to all hwaccels. This does not affect
the current vdpau API, as av_vdpau_bind_context() should obviously
override the AVCodecContext.hwaccel_flags flags for the sake of
compatibility.

In this case, the user only supplies a device and the frame context
is allocated internally by lavc.
