16a163b55a lavc: Add hwaccel_flags field to AVCodecContext
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.

b7487f4f3c hwcontext: Make it easier to work with device types
Adds functions to convert to/from strings and a function to iterate
over all supported device types.  Also adds a new invalid type
AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value.

76e13bdeaa ffmpeg: restructure sending EOF to filters
Be more careful when an input stream encounters EOF when its filtergraph
has not been configured yet. The current code would immediately mark the
corresponding output streams as finished, while there may still be
buffered frames waiting for frames to appear on other filtergraph
inputs.

This should fix the random FATE failures for complex filtergraph tests
after a3a0230a98

This merges Libav commit 94ebf55. It was previously skipped.

This is the last filter init related Libav commit that was skipped, so
this also removes the commits from doc/libav-merge.txt.

ade7c1a232 avcodec/videotoolbox: allow not setting the kCVPixelBufferPixelFormatTypeKey
If AVVideotoolboxContext.cv_pix_fmt_type is set to 0, don't set the
kCVPixelBufferPixelFormatTypeKey value on the VT decoder.

This makes VT output its native format, which can be much faster on
some hardware iterations (if the native format does not match with
the requested format, it will be converted, which is slow).

The default is still forcing nv12.

554bc4eea8 avcodec, avutil, avformat: remove AVOption requirement for some fields
Allow all struct fields to be accessed directly, as long as they're
public.

Before this change, many fields were "public", but could be accessed via
AVOption only. This meant they were effectively not public, but were
present for documentation purposes, which was incredibly confusing at
best.

e3af49b14b AVFrame: add an opaque_ref field
This is an extended version of the AVFrame.opaque field, which can be
used to attach arbitrary user information to an AVFrame.

The usefulness of the opaque field is rather limited, because it can
store only up to 32 bits of information (or 64 bit on 64 bit systems).
It's not possible to set this field to a memory allocation, because
there is no way to deallocate it correctly.

The opaque_ref field circumvents this by letting the user set an
AVBuffer, which makes the user data refcounted.
