The parser depends on the codec and thus must not be used with a different one.
If it is, the 'avctx->codec_id == s->parser->codec_ids[0] ...' assert in
av_parser_parse2 gets triggered.

Some people seem to oppose this the patch seems to have been missed for a month on the ML
lets restart the discussion and solve this after the release
This reverts commit e936c8d176.
Allowing larger timestamps makes it impossible to calculate basic things like the
difference of 2 timestamps or their sum without checking each individual computation for
overflow.
This should avoid a significant number of overflow checks
Fixes Ticket5136

If probe_codec is called with pkt == NULL, it sets probe_packets to 0
and request_probe to -1.
However, request_probe can change when calling s->iformat->read_packet
and thus a probe_packets value of 0 doesn't guarantee a request_probe
value of -1.
In that case calling probe_codec again is necessary to prevent
triggering the assert.

This also fixes a minor bug introduced in the codecpar conversion, where
the termination condition for extracting the extradata does not match
the actual extradata setting code. As a result, the packet durations
made up by lavf go back to their values before the codecpar conversion.
That is of little consequence since that code should eventually be
dropped completely.
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
It is supposed to be a flag. The only currently defined value is
AVIO_SEEKABLE_NORMAL, but other ones may be added in the future.
However all the current lavf code treats this field as a bool (mainly
for historical reasons).
Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.
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.

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
code easier to understand and work with. It does not solve the problem without
st->codec access

Commit 9200514ad8 ("lavf: replace AVStream.codec with
AVStream.codecpar") merged in commit 6f69f7a8bf changed
avformat_find_stream_info() to put the extradata it got from
st->parser->parser->split() to st->internal->avctx instead of st->codec
(extradata in st->internal->avctx will be later copied to st->codecpar).
However, in the same function, the "is stream ready?" check was changed
to check for extradata in st->codecpar instead of st->codec, even
though st->codecpar is not yet updated at that point.
Extradata retrieved from split() is therefore not considered anymore,
and avformat_find_stream_info() will therefore needlessly continue
probing in some cases.
Fix that by checking for the extradata at st->internal->avctx where it
is actually put.
Add ff_format_output_open utility function to wrap
io_open callback of AVFormatContext structure.
