Correct the names of the format-specific headers (not hwframe_*.h)
and clarify that the user shall ignore this field if there is no
public context associated with it.
In particular, this allows to use this field for the private context
alone if there is no public context. This can't break conforming
API users, because they always have to live with the possibility
that a new public context has been introduced.

Without ff_vk_exec_discard_deps which is called by ff_vk_exec_wait,
the reference count of hwframe context cannot reach zero due to
circular reference created by ff_vk_exec_add_dep_frame.

It was always intended that the buffers returned by
RefStruct shall have the same alignment guarantees
as the buffers returned by av_malloc(); said alignment
depends upon the arch and the enabled instruction set
and the code used STRIDE_ALIGN as a proxy for this.
Yet since 7945d30e91
there is a better way to get av_malloc's alignment:
ALIGN_64 in mem_internal.h. So use this.

Cloning a packet whose source is going to be unreferenced
immediately afterwards is wasteful.

This decoder uses av_image_copy() to copy decoded images
to buffers obtained via ff_get_buffer(); ergo it can handle
user-provided buffers.

This decoder implements the receive_frame API; such decoders
always have to set the pkt_dts field themselves and the avcodec
test checks for this.

Fixes errors when opening streams with no extradata (like those from raw OBU
sources). It also calls get_format() on new Sequence Headers when required.

Commit 900ce6f8c3 replaced
IntraX8Context.ac_vlc by IntraX8Context.ac_vlc_table,
but forgot to update an av_assert2()*.
cf7ed01938 then
replaced this with a check for j_ac_vlc[mode],
but this makes no sense as j_ac_vlc is of type
const VLCElem [2][2][8][].
Worse yet, mode can be up to three and then
j_ac_vlc[mode] is undefined behaviour. This happened
during the wmv8-x8intra FATE test.
*: Since 84f16bb5e6
config.h was no longer auto-included in avassert.h
and this disabled av_assert1() and av_assert2()
in files where config.h has not been included before
the inclusion of avassert.h.

So that can show OBU info even it doesn't have decomposed content. And
add OBU content status into the message.
