56fc5bef18 aggregator: Remove klass->sinkpads_type 
This posed problems for the python bindings (and possibly others).

Instead, subclasses now use add_pad_template_with_gtype.

1116bb00ca aggregator: use new gst_element_foreach_sink_pad() 
Instead of gst_aggregator_iterate_sinkpads() which will
soon be removed.

0a2ff1ecda aggregator: fix type for latency property (int64 -> GStClockTime)

bb5a8ebec3 aggregator: Don't block if adding to the tail of the queue 
If we're adding to the tail of the queue, it's because we're converting
a gap event, so don't block there it means we're calling from the output
thread.

739d488cea aggregator: review code related to time level 
Add a comment for when the state matters. Use a local var for priv in
update_time_level() to improve readability. Move the our_latency local
var below the query results checks.

87dcd2959d aggregator: code cleanup for event and query func 
Only look up klass for non serialized events/queries. For events remove
superfluous assignment for the return value in the flushing case.

7562d759a5 aggregator: simplify pad_event_func for FLUSH_STOP events 
We want to skip serialization for FLUSH_STOP events (apparently). We can
simplify the code to add it to the top-level conditions. There was nothing
done in the first code path if the event was FLUSH_STOP.

a3190f1765 aggregator: drop special casing for eos 
Just queue it like any other serialized event. This way we don't need to
check if there still are buffers in the queue.

Validated with the tests and gst-launch-1.0 pipelines.

08a7da766d aggregator: rename a local variable 
The variable tracks wheter the queue is not empty, but num_buffers==0. That
means we have events or queries to process. Rename accordingly.

7d97004dd7 aggregator: cleanup event forwarding 
Don't copy the whole event struct. Set the input params when we call the
forwarding helper. Initialize the internal fields and return values in the
helper.

324977fd7c aggregator: simplify src_event 
Avoid extra ref/unref, we have a ref and do_seek unrefs. Just return the result
as we have. This lets us remove the local var plus the label.

7c3bfbb512 aggregator: Remove the GAP event from the queue before queueing up the GAP buffer 
Otherwise check_events() will not remove the GAP event (as the queue
tail is not the event anymore but the GAP buffer), then the GAP buffer
is handled, then the GAP event is handled again, ... forever.

86a256aebc aggregator: Process serialized queries through the queue 
This ensures that they really get processed in order with
buffers. Just waiting for the queue to be empty is sometimes not
enough as the buffers are dropped from the pad before the result is
pushed to the next element, sometimes resulting in surprising
re-ordering.

ed8512c53e aggregator: Reset upstream latency on first buffer 
In the case an aggregator is created and pads are requested but only
linked later, we end up never updating the upstream latency.
This was because latency queries on pads that are not linked succeed,
so we never did a new query once a live source has been linked, so the
thread was never started.
