56f17407bc matroska: Add the CueDuration element
Use it only on subtitle CuePoints.
With proper demuxer/splitter support this should improve the display
of subtitles right after seeking to a given point in the stream.

The muxer has been creating files with v4 elements for some time now,
and especially now that we can mux non-experimental Opus files, reporting
the DocTypeVersion as 2 is not correct.

d92b1b1bab lavf/matroska: Adding support for Opus CodecDelay
In order to represent the codec delay accurately in Matroska, a
new element CodecDelay has been introduced. It contains the
overall delay added by the codec in nanoseconds. This patch adds
support for muxing CodecDelay value in the container.
Matroska spec for CodecDelay element can be found here:

bb47aa5850 opus/matroska: Adding support for DiscardPadding in muxer
Support for end trimming Opus in Matroska is implemented by using
the DiscardPadding container element in the Block data. The last
chunk is stored as a Block instead of SimpleBlock and the
trimming information is stored and used to discard samples that
were padded by the Opus codec. This patch adds support for muxing
DiscardPadding element into the container with appropriate value.
Matroska spec for the DiscardPadding element can be found here:

90fc00a623 avformat/subtitles: add a next line jumper and use it.
This fixes a bunch of possible overread in avformat with the idiom p +=
strcspn(p, "\n") + 1 (strcspn() can focus on the trailing '\0' if no
'\n' is found, so the +1 leads to an overread).

Note on lavf/matroskaenc: no extra subtitles.o Makefile dependency is
added because only the header is required for ff_subtitles_next_line().

Note on lavf/mpsubdec: code gets slightly complex to avoid an infinite
loop in the probing since there is no more forced increment.

509642b4bd WebM muxer writes WebVTT subtitle track
The Matroska muxer now allows WebVTT subtitle tracks to be written
while in WebM muxing mode.

WebVTT subtitle tracks have four kinds: "subtitles", "captions",
"descriptions", and "metadata". Each text track kind has a distinct
Mastroska CodecID and track type, as described in the temporal
metadata guidelines here:

http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm

When the stream has codec id AV_CODEC_ID_WEBVTT, the stream packet is
serialized per the temporal metadata guidelines cited above. The
WebVTT cue is written as a Matroska block group. The block frame
comprises the WebVTT cue id, followed by the cue settings, followed by
the cue text.  (The block timestamp is synthesized from the cue
timestamp.)
