Adds YUV 4:1:1, 4:4:0 and 4:4:4 - these will be needed for JPEG decoding.

Also adds some extra fields to the main context structure that may
be needed by a hwaccel decoder.

This is needed by later hwaccel code to tell which encoding process was
used for a particular frame, because hardware decoders may only support a
subset of possible methods.

  cbs: Allocate the context inside the init function

This commit is a noop, see 6734eef6Merged-by: Mark Thompson <sw@jkqxz.net>

Deletes both filler NAL units and filler SEI messages.  (Annex B zero_bytes
between NAL units are already discarded by the read/write process.)

It's very large, and is only used in some FMO streams.

This should be added even if the first access unit does not contain
parameter sets.

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).

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

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.

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

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

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

From ffmpeg commit e4a6eb70.
