Use the next I/P/B or start code as the end of current frame.
Before the patch, extension start code, user data start code,
sequence end code and so on are treated as the start of next
frame.

Not only this is information that relies on the concept of a sequence of
frames, which is completely out of place as a field in AVFrame, but there are
no known or intended uses of this field.

Accept it and pass it through unchanged.
The standard requires that decoders ignore unknown metadata, and indeed
this is tested by some of the Argon coverage streams.
* take num_ticks_per_picture_minus_1 into account, since that is a part
of the framerate computation
* stop exporting num_ticks_per_picture_minus_1 into
AVCodecContext.ticks_per_frame, as that field is used for other
purposes (in conjunction with repeat_pict, which is not used at all by
av1)
For encoding, this field is entirely redundant with
AVCodecContext.framerate.
For decoding, this field is entirely redundant with
AV_CODEC_PROP_FIELDS.
H.264 and mpeg12 parsers need to be adjusted at the same time to stop
using the value of AVCodecContext.ticks_per_frame, because it is not set
correctly unless the codec has been opened. Previously this would result
in both the parser and lavf seeing the same incorrect value, which would
cancel out.
Updating lavf and not the parsers would result in correct value in lavf,
but the wrong one in parsers, which would break some tests.
Decoders will currently warn if an audio decoder not marked with
AV_CODEC_CAP_SUBFRAMES consumes less than the whole packet, but
* this happens for regular files
* this has no negative consequences
* there is no meeaningful action that can or should be taken in response
The warning is thus useless noise.
Currently, the -1 (MR) preset is disallowed as it's taken as the preset
option not set, and the only way to access it was through svtav1-params.

As a sideeffect this simplifies the equation, the high bits are different after this but only
the low 16bits are stored and used in later steps.

When tak_get_nb_samples() fails, it will currently write
AVERROR_INVALIDDATA as TAKStreamInfo.frame_samples. The parser will then
use this negative value as a frame duration, which leads to various
breakage.
Avoid this by returning the error code from tak_parse_streaminfo()
directly; never store negative values in the parsed header.
