h264_metadata: Use common SEI addition function

cbs_h264: Add utility functions to insert/delete SEI messages

cbs: Refcount all the things!

This makes it easier for users of the CBS API to get alloc/free right -
all subelements use the buffer API so that it's clear how to free them.
It also allows eliding some redundant copies: the packet -> fragment copy
disappears after this change if the input packet is refcounted, and more
codec-specific cases are now possible (but not included in this patch).

cbs_h264: Add hack for pic_timing with no active SPS

If there is exactly one possible SPS but it is not yet active then just
assume that it should be the active one.

cbs_h2645: Remove active ps references when it is replaced

cbs: Demote the "decomposition unimplemented" warning

This is harmless and should not be a warning - unknown units are passed
through to the write functions unchanged, and no other code will interact
with them.

vaapi_h265: Mark unused entries in RefPicList[01] as explicitly invalid

The iHD driver looks at entries beyond num_ref_idx_l[01]_active_minus1
for unknown reasons.

vaapi_encode: Destroy output buffer pool before VA context

The buffers are created associated with the context, so they should be
destroyed before the context is.  This is enforced by the iHD driver.

vaapi_encode: Allocate slice structures and parameter buffers dynamically

This removes the arbitrary limit on the allowed number of slices and
parameter buffers.

avcodec/mediacodecdec: refactor to take advantage of new decoding api

This refactor splits up the main mediacodec decode loop into two
send/receive helpers, which are then used to rewrite the receive_frame
callback and take full advantage of the new decoding api. Since we
can now request packets on demand with ff_decode_get_packet(), the
fifo buffer is no longer necessary and has been removed.

This change was motivated by behavior observed on certain Android TV
devices, featuring hardware mpeg2/h264 decoders which also deinterlace
content (to produce multiple frames per field). Previously, this code
caused buffering issues because queueInputBuffer() was always invoked
before each dequeueOutputBuffer(), even though twice as many output
buffers were being generated.

With this patch, the decoder will always attempt to drain new frames
first before sending more data into the underlying codec.
