aggregator: Block serialized events/queries until the pad has consumed all buffers
Otherwise the caps of the pad might change while the subclass still works with
a buffer of the old caps, assuming the the current pad caps apply to that
buffer. Which then leads to crashes and other nice effects.

audiomixer: critical error for blocksize, timeout min/max values
Audiomixer blocksize, cant be 0, hence adjusting the minimum value to 1
timeout value of aggregator is defined with MAX of MAXINT64,
but it cannot cross G_MAXLONG * GST_SECOND - 1
Hence changed the max value of the same

aggregator: add latency query handling
Matthew Waters [Mon, 6 Oct 2014 07:23:03 +0000 (18:23 +1100)]
aggregator: add a timeout property determining buffer wait time
Determines the amount of time that a pad will wait for a buffer before
being marked unresponsive.
Network sources may fail to produce buffers for an extended period of time,
currently causing the pipeline to stall possibly indefinitely, waiting for
these buffers to appear.
Subclasses should render unresponsive pads with either silence (audio), the
last (video) frame or what makes the most sense in the given context.

aggregator: Replace GMainContext with GAsyncQueue (v2)
The previous implementation kept accumulating GSources,
slowing down the iteration and leaking memory.
Instead of trying to fix the main context flushing, replace
it with a GAsyncQueue which is simple to flush and has
less overhead.

aggregator: Set seqnum only when segments are received.
Thibault Saunier [Sat, 2 Aug 2014 16:25:01 +0000 (18:25 +0200)]
aggregator: Add a streaming lock so to secure flush start action
Without a lock that is taken in FLUSH_START we had a rare race where we
end up aggregating a buffer that was before the whole FLUSH_START/STOP
dance. That could lead to very wrong behaviour in subclasses.

aggregator: Query seeking when a seek failed to see if it was expected
And do not worry if seeking failed on a stream that is not seekable
Mathieu Duponchelle [Thu, 17 Jul 2014 23:41:26 +0000 (01:41 +0200)]
aggregator: set future seqnum before propagating the seek event.
So the seqnum is properly set for the following events.

aggregator: Take lock to ensure set_caps is not called concurently
Avoiding to be in an inconsistent state where we do not have
actual negotiate caps set as srccaps and leading to point where we
try to unref ->srccaps when they have already been set to NULL.

videoaggregator: push the caps event as soon as we receive it
Along with the required mandatory dependent events.
Some elements need to perform an allocation query inside
::negotiated_caps(). Without the caps event being sent prior,
downstream elements will be unable to answer and will return
an error.
