videorate automatically fills gaps with the previous frames.

Each write will update the last_activity_time and otherwise we would
compare against a too old current time and immediately timeout because
current time is smaller than last activity time (overflow).

Otherwise we end up with bogus values and races

Base classes will handle re-negotiation if needed, but emitting an
error message will make applications stop.

And in some cases, just remove our implementation that does nothing

It maps a sample rate to a well known AAC sample rate index.

Remove dodgy code that detects mp3 with as little as
a valid frame sync at the beginning. This was only used
in some unit tests in -good where there were only a few
bytes after the id3 tag. We now require at least two
frame headers.

Fixes mis-dection of text files with UTF-16 LE BOM as mp3.

Otherwise it might shadow another variable in the outside scope
and cause interesting side effects.

The subclass will be called with set_format() and there it can drain
if necessary and reset whatever is necessary. This is the same behaviour
as for the video decoder.

Let gst_video_encoder_reset() call it as would be intuitive and
only call it indirectly from gst_video_encoder_drain(). Now it
actually makes sense.

only call it indirectly from gst_video_decoder_flush(). Now it
actually makes sense.

This is now all handled automatically with sticky events.

Including streams from external subtitle files. If not everything implements
the group-ids playbin invents its own.

This code needs a lot more work to be improved for 1.0.

Thanks to Mathieu Duponchelle for noticing this regression
introduced with the last change.

We have to hold the streams-lock when iterating over all pads,
also the stream-lock of the pad is already locked when we receive
EOS.

Call gst_pad_event_default() for the correct default handling of
events.
