When intra_refresh is enabled, gopLength is equal to
NVENC_INFINITE_GOPLENGTH. gopLength should be 1 at least.

Changes the result of fate-mxf-probe-dv25, where the bitrate is now
exported.
Also changes the result of fate-bsf-dv-error-marker, where the exported
bitrate is now different. Note that the codec layer bitrate does not
match the container bitrate, because container timing is 25fps, while
the DV profile is 50.
This way decoding errors will not be returned when the user starts
draining the decoder, avoiding confusion over whether draining did or
did not start.
Fixes failures of fate-h264-attachment-631 for certain numbers of frame
threads (e.g. 5).
Do it from ff_decode_get_packet() rather than from
avcodec_send_packet(). This way all nontrivial stages of the decoding
pipeline (i.e. other than just placing a packet at its entrance) are
pull-based rather than a mix of push an pull.
Decoding pipeline has multiple stages, some of which may have their own
delay (e.g. bitstream filters). The code currently uses
AVCodecInternal.draining to track all of them, but they do not have to
all be in sync.
The goal is to distinguish between APIs provided by the generic layer to
individual codecs and APIs internal to the generic layer.
Start by moving ff_{decode,encode}_receive_frame() and
ff_{decode,encode}_preinit() into this new header, as those functions
are called from generic code and should not be visible to individual
codecs.

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

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.
