Do not segfault when writing tracks such as tmcd by writing them down
as generic DataHandlers if not known.

Prevent an assert.

Data streams have a defined timebase, do not ignore it.

Allow emitting the current cluster that is being written before
starting a new one, simplifying how to figure out where clusters
are positioned in the output stream (for live streaming).

WebM files now support inband text tracks, as described in the
following specification:

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

The Matroska demuxer now detects the presence of WebVTT tracks,
synthesizing WebVTT packets (having codec id AV_CODEC_ID_WEBVTT) and
pushing them downstream in the normal way.

  ogg: Fix potential infinite discard loop

No change as this commit has been part of ffmpeg since a while already

See: d7b542aeMerged-by: Michael Niedermayer <michaelni@gmx.at>

Seeking in certain broken files would cause ogg_read_timestamp
to fail because ogg_packet would go into a state where all packets
of stream 1 would be discarded until the end of the stream.

This avoids the loss of a packet in many cases if the packet size was wrong.
It also improves detection of packet size changes

No case is known to have triggered this, but its more correct to check that the

Calculate the duration as accurately as possible to improve decoding of samples
where the last frame is smaller than the rest.

Example:
Take lossless-audio/luckynight-partial.tak from the FATE suit and convert it
to TTA muxed into matroska:

ffmpeg -i $(SAMPLES)/lossless-audio/luckynight-partial.tak -c:a tta lucky.mka

than uint32_t and as such stored as 2338172288.
With this patch the duration is correctly calculated as 418950.
