pts may not be set on input packets, which could result in the entire stream
being discarded.
This reverts commit 8fc2dedfe6, reintroducing the
behavior it replaced but now allowing the caller to manually drop the preroll
samples by looking at the skip_samples side data at the start while ignoring it
on seek, by setting the skip_manual avctx flag.
Fixes ticket #10251.

It is currently abused to store packet size, which breaks
AV_CODEC_FLAG_COPY_OPAQUE.
Use stream_index instead, which is unused in libavcodec and has the
same type as size.

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.

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

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.
