55e767b632 oggmux: prefer headers from caps to determine stream type
Ogg mandates the first header packet must determine a stream's type.
However, some streams (such as VP8) do not include such a header
when muxed in other containers, and thus do not include this header
as a buffer, but only in caps. We thus use headers from caps when
available to determine a new stream's type.

2319c85f46 oggdemux: perform more (vorbis comment header) tag extractions
In particular, move comment header parsing to gstoggstrem.c.
Thanks to Felipe Contreras.

Fixes #629349 (partially).

549bc3c80e oggdemux: use index to estimate bitrate
When we have an index, use it to much more accurately estimate the total stream
bitrate.

Remove some redundant code for parsing fishead streams. Actually use the data we
parsed (mostly start_time).

Parse the bitrate from the various streams.
Use the bitrate and the upstream length in bytes to estimate the total stream
duration in push mode.

0201326db1 oggdemux: push headers when activating chains
Keep a list of headers for each stream of a chain. When a chain is activated,
push the headers before pushing the data so that decoders can sync.
Fix seeking in chains, take the chain start time into account when comparing
timestamps.

See #606382

8bbe0d126a oggdemux: reimplement OGM support
OGM demuxing no longer requires helper elements.  It's done internally
in oggdemux.  Vorbis comments are still not handled because I don't
have anything to test with.

8c202593c6 oggdemux: Fix timestamp generation for theora
Timestamp generation was broken by the last commit for formats
with a non-zero granule shift.  Also keep track of the last keyframe
so that we can regenerate granulepos for theora.

78aad52cbf oggdemux: Fix vorbis parsing
Add a granule to granulepos conversion function.  Fix the duration
function for vorbis.  Handle timestamps on header packets differently
and be more careful about calculating OFFSET and OFFSET_END.  After
this change, timestamps for vorbis don't exactly match up with the
timestamps that vorbisparse outputs, but it's unclear if vorbisparse
is actually correct and it would add a lot more code to make oggdemux
match vorbisparse.  Fixes #602790.

72edd1467b ogg: Add ogg stream parsing
Adds code that parses headers of various formats encapsulated in
Ogg in order to calculate timestamps and durations of each buffer.
Removes the creation of helper decoder elements to do this calculation
via conversion queries.

Fixes: #344013, #568014.
