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.

The issue is that while decode_slice is guaranteed to never get
called without start_frame, end_frame is not. Moreover, it is
not guaranteed it won't be called twice.
On a badly-broken sample, this is what happens, which leads to
a segfault, as vp->slices_buf doesn't exist, as it has been handed
off for decoding already and isn't owned by the frame.
Return an error as it's indicative that it's a corrupt stream rather
than just missing any slices.
Prevents a segfault.
