Store the seek stop and seqnum and properly restore them when
receiving the corresponding Segment from upstream. Also fixes
seqnum for converted seek events.
When bisecting after an earliest time has been found, we need
to only consider the stream for which the earliest time was found.
Before, the following scenario could be and was encountered:
a) Find the earliest time for stream X
b) bisect and find a page which granuletime is indeed < target, but
contains another stream.
c) decide to seek at the wrong offset, sometimes inferior to
the real one, in which case the error was undected or
d) the offset was superior, and thus the actual target keyframe was
not processed, and packets were skipped waiting
for a granulepos.

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.
