videoaggregator: Make sure to always update the pad's videoinfo together with buffers
Otherwise the videoinfo and the buffer content can go out of sync.

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.

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.

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.

instead of dropping them for being too old. This ensures that
the newest buffer is always used for rendering

gl: add a sync meta for synchronizing across GL contexts
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.
This meta would be placed on buffers that are known to cross from
one context to another. The receiving element would then wait
on the sync object to ensure that the data to be used is complete.
