3206ea4ba3 avformat/utils: Also fill dts==RELATIVE_TS_BASE packets in update_initial_durations()
This dts value can end up in the list in the absence of durations and is in that
case semantically identical to AV_NOPTS_VALUE. We can alternatively prevent
storing RELATIVE_TS_BASE if there is no duration.

Fixes Ticket3640

fe7547d69e lavf/utils.c Protect against accessing entries[nb_entries]
In ff_index_search_timestamp(), if b == num_entries,
m == num_entries - 1, and entries[m].flags & AVINDEX_DISCARD_FRAME is
true, then the search for the next non-discarded packet could access
entries[nb_entries], exceeding its bounds. This change adds a protection
against that scenario. Reference: https://crbug.com/666770

e936c8d176 avformat/utils: Discard huge timestamps which would cause overflows if used in basic computations
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

a5b4476a60 avformat: prevent triggering request_probe assert in ff_read_packet
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.

955b818cf9 ffmpeg: switch to codecpar
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.

60873bf992 avformat/utils: Fix find_stream_info not considering the extradata it found
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.
