589c455ccb baseparse: use _set_frame_props to configure frame lead_in and lead_out
... provided a corresponding decoder with sufficient leading and following
frames to carry out full decoding for a particular segment.

f218b984cc baseparse: use _set_duration to configure duration update interval
... as it logically belongs there as one or the other; either subclass
can provide a duration, or an estimate must be made (reguarly updated).

0198d6320b baseparse: remove is_seekable vmethod and use a set_seek instead
Seekability, like duration, etc is unlikely to change (frequently), and
the default assumption covers most cases, so let subclass set when needed.
At the same time, allow subclass to indicate if it has seek-metadata (table)
available, and possibly have it provide an average bitrate.

3448e83c73 baseparse: Allow chaining of subclass event handlers
This allows the child class to chain its event handler with
GstBaseParse, so that subclasses don't have to duplicate all the default
event handling logic.

a459494097 baseparse: fix seek handling
Allow a few more seek event type combinations, and really use the result
of gst_segment_set_seek to perform the seek.  Also add some debug.

f7e228edb0 baseparse: Don't emit bitrate tags too early
We wait to parse a minimum number of frames (10, arbitrarily) before
emiting bitrate tags so that our early estimates are not wildly
inaccurate for streams that start with a silence. If the stream ends
before that, we just emit the tags anyway.

While it _would_ be nicer to be specify the threshold to start pushing
the tags in terms of duration, this would introduce more complexity than
this merits.

017bb65d06 baseparse: Send NEWSEGMENT event with correct start and position
Instead of taking the last stop (which could be buffer endtime instead
of starttime) always take the buffer starttime.

Fixes bug #614016.

733669e076 audioparsers: Add bitrate calculation to baseparse
This makes baseparse keep a running average of the stream bitrate, as
well as the minimum and maximum bitrates. Subclasses can override a
vfunc to make sure that per-frame overhead from the container is not
accounted for in the bitrate calculation.

We take care not to override the bitrate, minimum-bitrate, and
maximum-bitrate tags if they have been posted upstream. We also
rate-limit the emission of bitrate so that it is only triggered by a
change of >10 kbps.

fd848904f9 baseparse: adjust seek handling and newsegment sending
Perform sanity check on type of seek, and only perform one that is
appropriately supported.  Adjust downstream newsegment event
