9efd519c81 gstcheck: Ensure unused threadpool threads are stopped
Ensures that all unused threads are exited before the atexit()
handlers run.

This prevents a race with any thread that used the OpenSSL library
between it's thread cleanup routine and it's atexit() cleanup routine
which can cause a SIGSEGV.

1a8dfdfc54 Introduce gst_element_request_pad_simple
The name `gst_element_get_request_pad()` is confusing to people
learning GStreamer. `gst_element_request_pad_simple()` aims at
providing the exact same functionality, while making it more
explicit it is a simplified `gst_element_request_pad()`.

`gst_element_request_pad_simple()` is consistent with other
functions such as `gst_element_seek_simple`.

This commit deprecates `gst_element_get_request_pad()` so that a
compilation warning is emitted when used and incite developers
to use the more explicit `gst_element_request_pad_simple()`.

defe732ae0 aggregator: Release pads' peeked buffer when removing the pad or finalizing it
The peeked buffer was always reset after calling ::aggregate() but under
no other circumstances. If a pad was removed after peeking and before
::aggregate() returned then the peeked buffer would be leaked.

This can easily happen if pads are removed from the aggregator from a
pad probe downstream of the source pad but still in the source pad's
streaming thread.

e600c85aee aggregator: Include min-upstream-latency in buffering time
While we can fixe the upstream latency using the min-upstream-latency, we
are now forced to use queues (hence more thread) in order to store the pending
data whenever we have an upstream source that has lower latency.

This fixes the issue by allowing to buffer the fixed upstream latency. This is
particularly handy on single core systems were having too many threads can
cause serious performance issues.

d74efc1aed aggregator: expose sample selection API
See https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/771
for context.

This exposes new API that subclasses must call from their
aggregate() implementation to signal that they have selected
the next samples they will aggregate: gst_aggregator_selected_samples()

GstAggregator will emit a new signal there, `samples-selected`,
handlers can then look up samples per pad with the newly-added
gst_aggregator_peek_next_sample.

In addition, a new FIXME is logged when subclasses haven't actually
called `selected_samples` from their aggregate() implementation.
