With FCPX 10.4, Apple has expanded the set of colorspace, primaries,
and trc flags officially supported in QuickTime files. The expanded set
matches the codepoints used in ffmpeg and many other specs.

If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.
Added option allows users to select between replacement and composition.
Tested and documented.

avcodec: add metadata to identify wrappers and hardware decoders
This commit is a noop, see b945fed629
Merged-by: James Almer <jamrial@gmail.com>
Explicitly identify decoder/encoder wrappers with a common name. This
saves API users from guessing by the name suffix. For example, they
don't have to guess that "h264_qsv" is the h264 QSV implementation, and
instead they can just check the AVCodec .codec and .wrapper_name fields.
Explicitly mark AVCodec entries that are hardware decoders or most
likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing
API users listing hardware decoders in a more generic way. The proposed
AVCodecHWConfig does not provide this information fully, because it's
concerned with decoder configuration, not information about the fact
whether the hardware is used or not.
AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software
implementations in case the hardware is not capable.
Based on a patch by Philip Langdale <philipl@overt.org>.

Hypothetical Reference Decoding (HRD) model assumes that data flows
into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
Smaller BufferSizeInKB means smaller frame size variations,
but more difficult to maintain HRD.

This reverts commit 590136e78d.
Atomics are not required for this variable, because it is protected
through the lock manager, and the use of atomics here is not compatible
with the c11 emulation wrappersi.
Fixes FATE on MSVC, among other setups which use the compat wrappers.

This fixes the use of old ad-hoc methods which are still supported by some
hwaccels which also support newer methods (DXVA2, VAAPI, VDPAU,
videotoolbox) - without the method being visible here, ff_get_format()
would refuse to use it.
