This ensures the requested amount of bytes is read.
Also remove /dev/random as it's no longer necessary.

The HDR metadata should be removed after HDR to SDR conversion,
otherwise the output frame still has HDR side data.

This makes the filter output match that of the C version.
It was left intentionally while we figured out if it was better
or not, and while it makes certain samples better, it makes static
samples jump around slightly.
The standard only defined configurationVersion 1.
configurationVersion 0 is for backward compatibility predates the
standard.
This patch reduces the chance that some malformated streams being
detected as hvcC.

Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output. We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.
Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets. This is
because subsequent patches will introduce support for other
data codecs.
Thanks to Marton Balint for review/feedback.

The existing queue initialization function would always sets it's
maximum queue size to ctx->queue_size. But because we are introducing
more queues we may want the sizes to differ between them.
Move the specification of the queue size into an argument, which can
be passed from the caller.
This patch makes no functional change to the behavior. It is being
made to accommodate Marton Balin's request to split out the queue
size for the new VANC queue being introduced in a later patch.

No need to generate intermediate files and probe them. We only care to know that the
output of the bsf excludes the frames in question, and a simple checksum is enough.

VVCParserContext.au_info is only used once (and in a read-only manner);
but this happens immediately after au_info has been completely
overwritten. Therefore one can just the src structure used to overwrite
au_info directly and remove au_info.
This also means that the whole referencing and unreferncing of au_info
(which duplicates AVBufferRefs CodedBitstreamH266Context and is
therefore of dubious gain) can be removed, as can the AVBufferRef*
contained in PuInfo; this also removes a certain uglyness: Sometimes
these AVBufferRef* were ownership pointers and sometimes not.
