playbin3/urisourcebin: Enable buffering by default
This only has effect on network streams in these elements, and by
enabling it by default we get the same behaviour as in playbin2.

Use new message notify API and print caps and taglists in a nicer
to read way, just like gst-launch-1.0 does nowadays, without
escaping everything three times.

oggdemux: Fix reverse playback
Fix various issues with reverse playback by clearing tracking
vars when working in reverse, and where possible using the
timestamp interpolation code to generate timestamps for
outgoing buffers. Make sure to mark things as discontinuous
only when looping backward to a new position and fix seeking
to the next page when starting.

oggdemux: Timestamp tracking fixes
In gst_ogg_demux_do_seek() when calculating the
keyframe time, account for a non-zero start-time
Handle a discontinuous first packet in
gst_ogg_demux_setup_first_granule() because that's pretty
normal after a seek. Also differentiate between a genuinely
truncated first packet and just bailing out early, by not using
granule = -1 as an error code.
Make the debug output logs clearer about which timestamps
are stream times (PTS) and which are ogg timestamps.

videodecoder: Restrict frame timestamp guessing in reverse mode
Don't guess a timestamp of the start of the segment when running
in reverse mode, as more likely it means we're discontinuous somewhere
in the middle of the segment, and we'll fix up timestamps once
the frames are decoded and reversed.
