Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.

This reverts commit 2cf8355f98.
AVInputStream.nb_streams tracks number of streams found at the
beginning, new streams may appear that ffmpeg doesn't know about. Fixes
crash in this case.

Parse the extension flag bit when reading the MPEG4 AudioSpecificConfig.
This has nothing to do with SBR/PS contradictory to what was noted when it was removed.

Some versions of the GNU assembler do not handle 64-bit
immediate operands containing arithmetic. Writing the

Set the frame size when decoding DTS audio.
This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes
the stream position without resetting current_id. The next
matroska_parse_cluster fails due to calculation of incorrect pos. So clear
current_id when avio_seek happens in matroska_read_seek.

Specifically crafted samples can reinit ogg->streams[] while
reading samples, and thus we should not cache old pointers since
these may no longer be valid.

This is the version available in Debian stable, so it should be a reasonable
baseline that can be expected to be present on all developer machines.
Moreover, this is the version that is used by the nightly cronjob that
generates the online html version.
