8bf53a1226 aggregator: make the src pad task drive the pipeline for live pipelines 
This removes the uses of GAsyncQueue and replaces it with explicit
GMutex, GCond and wakeup count which is used for the non-live case.

For live pipelines, the aggregator waits on the clock until either
data arrives on all sink pads or the expected output buffer time
arrives plus the timeout/latency at which time, the subclass
produces a buffer.

a7e86751bf videoaggregator: always try to use newer buffers 
instead of dropping them for being too old.  This ensures that
the newest buffer is always used for rendering

fbf7595ca8 videoaggregator: Copy over more fields from the relevant video-info 
gst_video_info_set_format() will reset the complete video-info, but
we want to keep values like the PAR, colorimetry and chroma site.
Otherwise we risk setting different values on the srcpad caps than
what is actually inside the buffers.

11740d78b1 videoaggregator: Do source pad negotiation only from the aggregated function 
Otherwise we might negotiate from the sinkpad streaming threads at
the same time as on the srcpad streaming thread, and then all kinds
of crazy bugs happen that don't make any sense at all.

9d8055186d videoaggregator: Expose vmethods to set converters and prepare/clean frames 
This gives more flexibility to the subclasses and permits to remove the
GstVideoAggregatorClass->disable_frame_conversion ugly API.

WARNING: This breaks the API as it removes the disable_frame_conversion
field

API:
  + GstVideoAggregatorClass->find_best_format
  + GstVideoAggregatorPadClass->set_format
  + GstVideoAggregatorPadClass->prepare_frame
  + GstVideoAggregatorPadClass->clean_frame

  - GstVideoAggregatorClass->disable_frame_conversion

c7b7f98df2 videoaggregator: Let a full renegotiation happen after removing the last pad 
With the current code, we will end up setting the preferred downstream
format as the srcpad format, and it might not be accepted by the next
sinkpad to be added. We should instead let the next sinkpad reconfigure
everything.

7091b0418d videoaggregator: Do not wrongly set the aggregator.segment 
The aggregator.segment is not to be initialized by the subclasses but
by the aggregator itself. Moreover, initializing it on start would make
us loose the information coming from the initial seek.

3637296ee9 videoaggregator: Do not to release VIDEO_AGGREGATOR_LOCK while setting format info 
We should be able to always keep the VIDEO_AGGREGATOR_LOCK while
negotiating caps, this patch introduce that change.

That also implies that we do not need the SETCAPS_LOCK anymore because
now VIDEO_AGGREGATOR_LOCK guarantees that setcaps is not called from
several threads and the gst_aggregator_set_caps method is now
protected.

f2af838837 videoaggregator: Revert the last commit and handle resolutions differences properly 
This is about converting the format, not about converting any widths and

7c016752d7 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.
