Commit 8b83dad825 introduced a
regression in a way that scaling via vpp_qsv doesn't work any longer
for devices with an MSDK runtime version lower than 1.19. This is true
for older CPUs which are stuck at 1.11.
The commit added checks for the compile-sdk version but it didn't test
for the runtime version.

Fixes decoding of sample https://streams.videolan.org/ffmpeg/incoming/720p60.mp4
on RPi4 after kernel driver commit:
staging: bcm2835-codec: Format changed should trigger drain
Reference:
linux/Documentation/userspace-api/media/v4l/dev-decoder.rst
"A source change triggers an implicit decoder drain, similar to the
explicit Drain sequence. The decoder is stopped after it completes.
The decoding process must be resumed with either a pair of calls to
VIDIOC_STREAMOFF and VIDIOC_STREAMON on the CAPTURE queue, or a call to
VIDIOC_DECODER_CMD with the V4L2_DEC_CMD_START command."

Reference:
linux/Documentation/userspace-api/media/v4l/dev-decoder.rst
"During the resolution change sequence, the OUTPUT queue must remain
streaming. Calling VIDIOC_STREAMOFF() on the OUTPUT queue would
abort the sequence and initiate a seek.
In principle, the OUTPUT queue operates separately from the CAPTURE
queue and this remains true for the duration of the entire
resolution change sequence as well."

avcodec_open2() is supposed to be thread-safe (those codecs
whose init functions are not thread-safe are guarded
by a global lock).

Since the MPEG-4 parser no longer initializes some MPEG-4 VLCs,
no VLC is initialized concurrently by multiple threads
(initializing static VLCs is guarded by locks and nonstatic VLCs
never posed an issue in this regard). So remove the code
in bitstream.c that only exists because of this possibility.

It can't any longer, because all users of ff_rl_init() are now
behind ff_thread_once() or the global codec lock. Therefore
the check for whether the RLTable is already initialized can be removed;
as can the stack buffers that existed to make sure that nothing is ever
set to a value different from its final value.
Similarly, it is not necessary to check whether the VLCs associated
with the RLTable are already initialized (they aren't).

Both the MPEG-4 parser as well as the decoder initialized
several VLCs. There is a "static int done = 0;" in order to
guard against initializing these multiple times, but this does
not work when several threads try to initialize these VLCs
concurrently, which can happen when initializing several parsers
at the same time (they don't use the global lock that is used
for codecs without the FF_CODEC_CAP_INIT_THREADSAFE cap; actually,
they don't use any lock at all).
Since ff_mpeg4_decode_picture_header() now aborts early when called
from the parser, it no longer needs to have these VLCs initialized
at all. This commit therefore does exactly this.

Namely, skip some elements that are only useful for a decoder
when calling ff_mpeg4_decode_picture_header() from the MPEG-4 parser.
In particular, this ensures that the VLCs need no longer be
initialized by the parser.

iec61883_parse_queue_hdv() is only called when the mpegts-demuxer
is available and can be optimized away when not. Yet this
optimization is not a given and it fails with e.g. GCC 11 when
using -O0 in which case one will get a compilation error
because the call to the unavailable avpriv_mpegts_parse_packet()
is not optimized away. Therefore #if the offending code away
in this case.

parse_rtsp_message() is only called if the rtsp demuxer is enabled
and so it is normally compiled away if said demuxer is disabled.
Yet this does not happen when compiling with -O0 and this leads
to a linking failure because parse_rtsp_message() calls functions
that may not be available if the rtsp demuxer is disabled.
Fix this by properly #if'ing the unused functions away.

Only allocate an audio stream if there is one in the data. Silicon
Graphics movie format will contain default values (16 bit samples, 2
audio channels, 22050 Hz sample rate) even when no audio is present in
the file. This confuses FFmpeg into thinking such an audio stream is
present with 0 samples in it.
There is a flag value in the format to indicate whether or not audio is
present. This patch checks that and behaves accordingly.
