According to https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/mediasdk-man.md#configuration-change.
Before calling MFXVideoENCODE_Reset, The application needs to retrieve
any cached frames in the SDK encoder.
A loop is added before MFXVideoENCODE_Reset to retrieve cached frames
and add them to async_fifo, so that dynamic configuration works when
async_depth > 1.

When encode RGB frame, Intel driver convert RGB to YUV, so we cannot
set RGB colorspace to VPL/MSDK.

Their usefulness is questionable, very few decoders set them, and their type
should have been int64_t. A replacement field can be added later if a valid use
case is found.

Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.
Also deprecate the old 32 bit frame_number attribute.

libavutil/color_utils contains some avpriv_ symbols that map
enum AVTransferCharacteristic values to gamma-curve approximations and
to the actual transfer functions to invert them (i.e. -> linear).
There's two issues with this:
(1) avpriv is evil and should be avoided whenever possible
(2) libavutil/csp.h exposes a public API for handling color that
already handles primaries and matricies
I don't see any reason this API has to be private, so this commit takes
the functionality from avutil/color_utils and merges it into avutil/csp
with an exposed av_ API rather than the previous avpriv_ API.
Every reference to the previous API has been updated to point to the
new one. color_utils.h has been deleted as well. This should not break
any applications as it only contained avpriv_ symbols in the first
place, so nothing in that header could be referenced by other
applications.

It has been deprecated in 94d68a41fa
and can't be set via AVOptions. The only codecs that use it
(the MPEG-1/2 encoders) have private options for this.
So remove it.

We parse the fallback cHRM on decode and correctly determine that we
have BT.709 primaries, but unknown TRC. This causes us to write cICP
where we shouldn't. Primaries without transfer can be handled entirely
by cHRM, so we should only write cICP if we actually know the transfer
function.
Additionally, we should avoid writing cICP if there's an ICC profile
because the spec says decoders must prioritize cICP over the ICC
profile.

Since many distributions ship libjxl 0.7.0 still, we'd still prefer to
compile against that, but don't want to lose the features that require
libjxl 0.8.0 or greater. For this reason I've added preprocessor #ifdef
guards around the features that aren't necessarily in libjxl 0.7.0.
