4914aeda2f oggdemux: Don't leak allocated buffers 
This can happen if the combined flow return is not OK although the
allocation succeeded or if the packet in question is a BOS and we're
not going to push headers.

Fixes bug #608699.

ed2e09133e oggdemux: sparse streams aren't timed by end time, and their duration isn't implicit 
Fixes timestamps and durations on Kate subtitle streams.

See http://www.xiph.org/ogg/doc/ogg-multiplex.html section 'start-time and
end-time positioning' for some more details, and bug #600929.

mode too eventually.

e1c319949d oggdemux: fix crash when freeing headers 
Use _ogg_packet_free() instead of gst_mini_object_unref in one more
place now that the header list contains ogg packets and not buffers.

4b771bff7a oggdemux: No need to subtract begin time 
Last stop is already based on the chain start and there is no need
to subtract the chain start as it may lead to a negative overflow.
This was causing seeking issues when the target chain was not
the first one (that has chain start = 0)

Fixes #606382

125f7dfdb0 oggdemux: granulepos is relative to its chain 
When performing seeks, the granulepos should be offset by
its chain start time to avoid using wrong values to
update segment's last_stop. A sample file is indicated on

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.

c53cd385e3 oggdemux: implement keyframe seeking 
Implement keyframe seeking in oggdemux by doing the double seek trick. First
seek to the required position, then read pages for all streams to grab the
granulepos (to know the timing of the keyframe) of each stream, then seek back
to the first keyframe.

56d3856620 oggdemux: fix timestamps after seek 
After a seek, discard all packets before the packet with the granulepos on it so
that the output buffers contain valid timestamps.

Reorder some code so that we check the timestamps before allocating and pushing
an output buffer.

Do more checks on valid packets in ogm mode.
