b27fb0dbac aggregator: keep chain functions as dumb as possible.
+ A pad chain function has no business checking other pads,
  that's what the aggregate thread is for.

ccf329d527 aggregator: More fixes around locking when accessing protected private fields
In some more places we were accessing GstAggregator->segment
and GstAggregator->seqnum without holding the GST_OBJECT_LOCK

1a07467d5f aggregator: Make the PAD_LOCK private
Instead of using the GST_OBJECT_LOCK we should have
a dedicated mutex for the pad as it is also associated
with the mutex on the EVENT_MUTEX on which we wait
in the _chain function of the pad.

The GstAggregatorPad.segment is still protected with the
GST_OBJECT_LOCK.

Remove the gst_aggregator_pad_peak_unlocked method as it does not make
sense anymore with a private lock.

d8eef43123 aggregator: Hide GstAggregatorPad buffer and EOS fileds
And add a getter for the EOS.

fb6ba27ae5 audiomixer: Make flush start/stop test non-racy
The flush stop could have happened between the source trying
to push the segment event and the buffer, this would cause a warning.
Prevent that by taking the source's stream lock while flushing.

f98e457f99 audiomixer: Replace racy timeout based tested with drain query
Using the drain query, we can be certain that the buffer has done going
through the aggregator by taking the stream locks.

f7070dcfdc aggregator: Protect the srcpad caps negotiation with the stream lock

taken anyway to push out the new caps if needed.

0a2dc1185c aggregator: Protect data with the same mutex as GCond

878b53f8fc videoaggregator: If getting a timeout before having caps, just advance our position
This can happen if this is a live pipeline and no source produced any buffer
and sent no caps until an output buffer should've been produced according to the
latency.

This fix is similar in spirit to commit be7034d1 by Sebastian for audiomixer.

4eb5cd9156 decklink{audio,video}sink: Only start scheduled playback once both sources are ready and we are in PLAYING
Otherwise we might start the scheduled playback before the audio or video streams are
actually enabled, and then error out later because they are enabled to late.

We enable the streams when getting the caps, which might be *after* we were
set to PLAYING state.

21168dd199 videoaggregator: fix crash when receiving buffer without timestamps
Unset out buffer in clip function when we unref the buffer to be
clipped, otherwise aggregator will continue to use the already-
freed buffer. Fixes crash when buffers without timestamps are
being fed to aggregator. Partly because aggregator ignores the
error flow return.
