find out if downstream supports certain metas.

Large streams would index one frame every second, which can get quite
large with multi-hour streams, so add an additional byte-based
minimum distance as well, which will kick in for long streams
and make sure we never have more than a couple of thousand index
entries.

Hacky, because the still-frame code all lives in -base, where we
can't use it - so this is a hacky duplication of -base code. Not
sure which way to fix this: Move baseparse to -base, or move still-frame
events to core?
Make the event handling more like what videodecoder does,
to ensure that all events are passed to child classes before being
placed on the pending queue or pushed onward.
We only deal in TIME format ourselves, but if the subclass can handle
converting other formats into TIME format, we can support that too.
Fixes seeking in DEFAULT (sample) format with flacparse,
and the flacdec unit test.
Don't just return FALSE for seek events with negative rates when
operating in push mode. An upstream demuxer may support this just
fine, so if we're not operating in pull mode always check upstream
first if it can handle the seek event. This fixes reverse playback
where the upstream demuxer supports it (e.g. with qtdemux). The
same code would work fine in 0.10, because baseparse will just
call the default pad event handler if FALSE was returned from the
baseparse event handler, and the pad event handler will just
forward it upstream. In 0.11 the baseclass or subclass is
responsible for chaining up to the parent class or forwarding the
event upstream in any case.
Disable reverse playback in pull mode for now, there seems to
be something going wrong with the segment configuration in that
case.
This specifies if a given taglist applies to the complete
medium or only this specific stream. By default a taglist
has a stream scope.
Fixes bug #677619.
Move code that checks for upstream seekability and all that to
the right place, otherwise it will never be done for formats
that have headers such as FLAC, as handle_and_push frame will
be called the first time only after headers have been processed
(and framecount is > 0). This then makes us report that we
can't seek, which disables the seek bar in totem.
... since processing might still continue (if e.g. NOT_LINKED)
and then proper state (e.g. offset) needs to be maintained
(e.g. to arrange for a new frame setup).
This avoids ending up with plenty of pending data (since we'll only
try to parse/push one frame from the incoming buffer).
Fixes increasing memory consumption when parsers aren't linked

Separate the bufferpool and allocator hints in the allocation query, some
of the values don't always make sense together.
Keep the bufferpool and its configuration together.
Keep the allocator and its parameters together.
Allow for multiple bufferpool configurations in the query.
Previously only the last would be pushed, which would cause
invalid running times downstream. This also fixes the handling
of update newsegment events.
The segment start adjustment code in pull mode should never trigger
anymore because the bisection code earlier would have already made
sure that we're at the desired position.
Also move the gap handling some lines below after sending the currently
configured segments. Otherwise we might fill gaps in a segment that is
not configured downstream yet.
