If our previous flow return was NOT_LINKED, don't try to push on the pads some
more. If we get a RECONFIGURE event on the pad, try to push on it again.
Changed the check to a current_time equal to the stop will produce
EOS instead of the next one. Also, segment.start can't be NONE, so removing
this check.

No need to copy buffers we put into the streamheader any more
now that we don't put caps on buffers any more, so there's no
danger of a refcount cycle.
A crafted file with invalid pages will cause repeated searches from
earlier offsets in steps of 8500 bytes, but reading till the end of
the stream. Since we know the maximum size of an Ogg page, we can
bound the search for next page, to get a linear behavior (though
still not good enough as it will read the entire file backwards if
there's no valid page till then).
Take chain lock when accessing chains. Fall back gracefully
when there's no current chain Hopefully fixes crash when
seeking in Jamendo or Magnatune streams in Amarok.

They're hardly used, and probably more confusing than anything
else, and it's not clear that anyone would really need to be
able to tell them apart at the media type level.
This never really took off - it's hardly used anywhere
and deprecated in favour of Kate. Exposing pads just
leads to confusing 'you are missing a plug-in' messages
when people come across such streams. We could still post
the data on the bus for applications to parse.
In case many packets fit on a page, we may not see a granpos for
a while, and granpos interpolation can wrap the 'frames since last
keyframe' part of the granpos, generating a granpos which is smaller
than what it should be.
This is fixed by detecting keyframe packets (at least for Theora),
and updating the last keyframe granpos from this.
This may still be generating potentially wrong granpos for streams
which have a Theora like granpos (keyframes, a max keyframe distance
and a count of frames since last keyframe), and which allow implicit
granules on packets. For these streams, a custom keyframe detection
routine should be plugged into their GstOggStream mapper.

When I first implemented push mode seeking, I removed the chain
freeing there as it could be used later. The current code does not
seem to do that though, so I'm restoring the previous freeing,
which plugs the leak while apparently not reintroducing use of
freed data with chained and normal files, both with gst-launch
playbin2 and Totem.
A first hang was happening when trying to locate a page backwards,
where we'd sync forever on the same page.
With that fixed, a second hang would happen after preparing an EOS
event, but with no chain created yet to send it to, the pipeline
would stay idle forever.
An element error is now emitted for this case.
This prevents trying to seek and failing, then ending up unable
to stream because we can't get back at the headers.
A more robust way would be to find a good place to reinject the
headers when a seek fails, but I can't seem to get this to work.
