The AVPacket given to an encoder's encode callback
is unreferenced generically on error.

FFmpeg's assembly code currently does not abide by the
plattform-specific ABIs wrt its handling of the X86 MMX flag:
Resetting the MMX state is deferred to avoid doing it multiple times
instead of ensuring that the CPU is in floating point state
upon return from any function.
Furthermore, resetting said state is sometimes done generically,
namely for all the decoders using the ordinary decode callback;
yet this is not done for the decoders using the receive_frame API.
This led to problems when MJPEG (and the MJPEG-based decoders)
were switched to the receive_frame API in commit
e9a2a87773, because ff_mjpeg_decode_sos()
only resets the MMX state on success, not on failure.
Such issues are probably still possible with SMVJPEG, which still
uses the receive_frame API. See issue #10210.
This commit therefore also resets the MMX state for
the receive_frame API to avoid any more surprises of this sort.

The base_enable_flag is parallel to three_Spline_enable_flag. The
typesetting of the specification is very misleading.

It conflicts the comments. The operation based on Delta_enable_mode
can be applied by user during tone mapping.

The original code would strip off the PTS/DTS of any packets
which had a stream ID of STREAM_ID_PRIVATE_STREAM_1. While the
intent was to apply this to asynchronous KLV packets, it was
being applied to any codec that had that same stream ID (including
types such as SMPTE 2038).
Add a clause to the if() statement to ensure it only gets applied
if the codec actually is KLV.

ipcm is defined by ISO/IEC 23003-5, not defined by quicktime. After
adding ISO/IEC 23003-5 support, we don't need it for ticket #9219.

This also fixes the number of planes for the NV formats
(this seems to not have caused any problems).

SSIM360Context.ssim360_hist is an array of four pointers to double;
so sizeof(*ssim360_hist[0]) (=sizeof(double)) is the correct size
to use to calculate the amount of memory to allocate, not
sizeof(*ssim360_hist) (which is sizeof(double*)).
Use FF_ALLOCZ_TYPED_ARRAY to avoid this issue altogether.
Fixes Coverity issue #1520671.

Generally if maxrate is set, the calculation should be maxrate over
bufsize. This additionally enables CRF + maxrate & bufsize usage.
In order to keep negative values from enabling zero to be treated
as larger and causing a division by zero, check that one of the
variables is larger than zero.
This has not been functional since a year ago, including in our current
minimum dependency of libplacebo (v4.192.0). It also causes build errors
against libplacebo v6, so it needs to be removed from the code. We can
keep the option around for now, but it should also be removed soon.

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.
