195e54e06a audiomixer: calculate stream_time used to sync pad values correctly 
Use pad (input) segment to calculate the stream time from the
input timestamp, not the aggregator (output) segment.

3c9ae895b0 Improve and fix LATENCY query handling 
This now follows the design docs everywhere, especially the maximum latency
handling.

6d6c693254 audiomixer: Remove weird and wrong segment handling 
There's no reason why audiomixer should override the segment
base of upstream with whatever value it got from a SEEK event,
or even worse... with 0 if there was no SEEK event yet. This
broke synchronization if upstream provided a segment base other
than 0, e.g. when using pad offsets.
Also that this code did things conditional on the element's state
should've been a big warning already that something is just wrong.
If this breaks anything else now, let's fix it properly :)

Also don't do fancy segment position trickery when receiving a
segment event. It's just not correct.

b1eef4f436 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.

198b16c563 aggregator: Hide GstAggregatorPad buffer and EOS fileds 
And add a getter for the EOS.

The user should always use the various getters to access
those fields

9071b8487c aggregator: Replace event lock with pad's object lock 
Reduce the number of locks simplify code, what is protects
is exposed, but the lock was not.

Also means adding an _unlocked version of gst_aggregator_pad_steal_buffer().

cd256acf03 audiomixer: 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 the an output buffer should've been produced according
to the latency.

eefea80dae audiomixer: Make sure to release the current buffer in reset() 
If we didn't output the last one in aggregate because we were shutting down
earlier we might otherwise leak it.

eff64c7ddc audiomixer: The pad's size is always supposed to be the whole buffer size 
And the offset the offset into that buffer. Changing the size will
cause all kinds of assumptions to fail and cause crashes.

06f6d3c65c aggregator: Add function to allow subclasses to set their own latency 
For audiomixer this is one blocksize, for videoaggregator this should
be the duration of one output frame.

46f713c598 audiomixer: Make sure to not have pads being behind the current offset

d508b39952 aggregator: Add a timeout parameter to ::aggregate() 
When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.

d38e242a72 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
