The earlier code used the most recent non-auxiliary slice to determine
whether an auxiliary slice has the syntax of an IDR slice, even when
the most recent slice was from a slice of a redundant frame. Now only
slices of the primary coded picture are used, as the specifications
mandate.

Flush the buffered data in libmfx before video param reinit
in case the frames drop.
Cache the first frame causing the reinit and decode zero-size
pkt to flush the buffered pkt before reinit. After all the
buffered pkts being flushed, resume to reinit and decode.
Fix the issue in ticket #7399.
[V2]: Move the definition of zero_pkt to where it is exactly
used.

libx264 does have a field for opaque data to pass along with frames
through the encoder, but it is a pointer, while the libavcodec
reordered_opaque field is an int64_t. Therefore, allocate an array
within the libx264 wrapper, where reordered_opaque values in flight
are stored, and pass a pointer to this array to libx264.
Update the public libavcodec documentation for the AVCodecContext
field to explain this usage, and add a codec capability that allows
detecting whether an encoder handles this field.

This was marked as deprecated (but only in the doxygen, not with an
actual deprecation attribute) in 81c623fae0 in 2011, but was
undeprecated in ad1ee5fa7.

buffer_delay_length_minus_1 is five bits long, meaning decode_buffer_delay and
encoder_buffer_delay can have values up to 32 bits long.
