8b60b25917 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.

a083391fb5 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.

fb3c9f3808 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.

8776900cf7 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.

5509920c27 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.

45cef5726f 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.

00d6f46ff8 aggregator: add two more tests for a sequence of data

then buffers.

fbe82b7fa1 aggregator: refactor the test helper

queries and data.

9efffd05e2 aggregator: test cleanup 
Remove gst_init() from a few tests. Use _OBJECT variants in logging. Remove
arbitrary extra blank lines. Make push_event() more like push_buffer() - set
the event to NULL and add cleanup to _chain_data_clear().

4808f4836c aggregator: cleanup event forwarding

forwarding helper. Initialize the internal fields and return values in the
helper.

a82e6bc650 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.

ab4dd3f577 check: Fix usage of dual probes 
Using two (or more) probes on the same pad where one of the probe
returns HANDLED or DROP is tricky since the other probes might
not be called.

Instead use regular probes and a proper pad (the sinkpad already existed,
it only required to be activated and have a dummy chain function for
the events/buffers to be received/handled properly)

70b4395e95 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.

474acca0a8 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.

c54d253301 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.
