This allows us to be more selective about the streams we derive durations from
(specifically, ignoring text streams with outlier end times) in the common case
The durations are never written in that situation.

This commit is largely based on commit 15e84ed3 from Anton Khirnov
<anton@khirnov.net> which was previously skipped in bbf5ef9d.
There are still a bunch of things raising codecpar related warnings that
need fixing, such as:
- the use of codec->debug in the interactive debug mode
- read_ffserver_streams(): it's probably broken now but there is no test
- lowres stuff
- codec copy apparently required by bitstream filters
The matroska references are updated because they now properly forward
the field_order (previously unknown, now progressive).
Thanks to James Almer for fixing a bunch of FATE issues in this commit.

This is mostly useful for muxers that wrap other muxers, such as dashenc
and segment. The actual duplicated bitstream filtering is largely harmless,
but delaying the header can cause problems when the muxer intended the header
to be written to a separate file.
ffmpeg have a generic solution working with all muxer named
output_ts_offset, output_ts_offset will instead of initial_offset

Fixes regressions with stream copy and output timebase/fps being twice as fine as needed
Makes the timebase and ticks per frame handled identical which should make the

Previously, we used a different list of checks when deciding whether to
write a set of tags at all than we did when deciding whether to write an
individual tag in the set. This resulted in sometimes writing an empty
tag master and seekhead. Now we use mkv_check_tag_name everywhere, so
if a dictionary is entirely composed of tags we skip, we don't write a
tag master at all.
This affected the test file, since "language" was on one list but not
the other, so we were writing an empty tag master there. The test hash
is updated to reflect that change.
This patch is a fix for the bug with ticket number 5812
(https://trac.ffmpeg.org/ticket/5812).
Basically, the bug is that the last segment and the "#EXT-X-ENDLIST"
tag are not being written to the subtitle playlist file when
converting a file with subtitles to the HLS format. The reason for
this seem to be that the filename for the subtitle file is being freed
too early. This solution is simply to free that memory after it's last
use in the "hls_window" function.

Sometimes it's useful to be able to define the exact track numbers in
the generated track, instead of always beginning at track id 1. Using
the option use_stream_ids_as_track_ids now copies the use stream ids
to track ids. Dynamically generated tracks (ie. tmcd) have their track
numbers defined as continuing from the highest numbered stream id.

cyrpto allows reading of data which has been aes-128-cbc encrypted given a key and an iv. But it did not handle filetypes which require seeking... e.g. it failed on an encrypted .mp4 file.
example:
take 25.mp4 created with:
ffmpeg -f lavfi -i sine=frequency=1000:beep_factor=2:r=48000:duration=720.0 -f lavfi -i testsrc=duration=720.0:rate=25 -vcodec libx264 -cmp 22 -timecode 10:00:00:00 -r 25 -y out\25.mp4
encrypt with:
openssl enc -aes-128-cbc -K 12345678901234567890123456789012 -iv 12345678901234567890123456789012 -in 25.mp4 -out 25.enc
then to transcode in ffmpeg:
ffmpeg -key 12345678901234567890123456789012 -iv 12345678901234567890123456789012 -i crypto:25.enc -vcodec mpeg4 -r 25 -y 25dec.mp4
prior to this modification, the transcode would fail.
Note also: crypto previously maked both reads and writes as streamed, which caused the whole file
to be read before the transcode started. Now, for read only, if the underlying layer is not marked as streamed,
then crypto is not. This should enable efficient reading of encrypted containers which require seeking.

av_log() expects its first parameter to be a pointer to a struct whose
first element is a pointer to an AVClass. In what I can only imagine is
a typo, one call to av_log() in the AAX decryption code instead passes
a pointer to an AVSHA struct, which doesn't even contain a pointer as
its first element, much less a pointer to an AVClass. Change the call to
pass the current MOVContext, as surrounding calls do.
The incorrect AVClass was causing mpv to emit the warning "av_log
callback called with bad parameters" when playing an .aax file.
