This patch adds support for creating DASH manifests for WebM Live
Streams. It also updates the documentation and adds a fate test to
verify the behavior of the new muxer flag.

This patch adds support for parsing live files (produced by
-f webm_chunk) which contains only the headers but no packets. This
is only used when using -f webm_dash_manifest. There will be a
follow up patch which adds live support to WebM DASH Manifest
muxer.

Generally, libavformat exports cover art pictures as video streams with
1 packet and AV_DISPOSITION_ATTACHED_PIC set. Only matroskadec exported
it as attachment with codec_id set to AV_CODEC_ID_MJPEG.
Obviously, this should be consistent, so change the Matroska demuxer to
export a AV_DISPOSITION_ATTACHED_PIC pseudo video stream.
Matroska muxing is probably incorrect too. I know that it can create
broken files with an audio track and just 1 video frame when e.g.
remuxing mp3 with APIC to mkv. But for now this commit does not change
anything about muxing, and also continues to write attachments with
AV_CODEC_ID_MJPEG should the muxer application have special knowledge
that the Matroska is broken in this way.
Fixes trac #4423.

mpegtsenc: Take max_delay into account when buffering multiple audio packets into one PES packet

I found another MXF File containing ProRes with the following
codec_uls: 060E2B34040101010E04020102110500
Therefor I relaxed the pattern.

Make sure we don't buffer up more than max_delay worth of data
before writing a PES packet, even if pes_payload_size is set to
a larger value.

The AVSC_API changes in the new headers mean that the 2.6 alphas
are just as incompatible as 2.5 is.

In order to safely exit when the user tries to use AviSynth 2.5,
the continue_on_fail value for 2.6's functions need to be set to
1. Otherwise, the library loader fails before the 'upgrade to
2.6' log message appears.

This prevents sub-muxers from trying to seek back to the beginning of the
whole stream, only to find themselves overwriting some video data in the
current (often last) segment.
We only do this when not writing individual header/trailers.
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
This permits some interesting segmenting techniques with formats like Matroska,
where you can concatenate the header and segments [N, nb_segments) and get
a working file that starts at segment N's start time.
