Otherwise deactivating them will cause a deadlock as they're blocking

9d195da36c inputselector: Push event on selected pad only when one is selected
Calling `gst_input_selector_get_active_sinkpad` triggers sinkpad
selection but won't notify about it, leading  to breaking code that
relying on it. This new code added as part of
63ccf45395 was thought to be triggered only
when a pad was already selected and not change the behavior otherwise
so this commit makes sure it is actually the case.

0c1ce6e8c4 utils: expose GstPluginAPIFlags
These can be passed to gst_type_mark_as_plugin_api, to inform
plugin cache generation.

For now a single flag is specified, "IGNORE_ENUM_MEMBERS", it
can be used for dynamically generated enums to avoid documenting
environment-specific enumeration members. An example is
GstX265EncTune.

f2478618b5 inputselector: Avoid deadlock when requesting pads
The deadlock was the following:
* One thread requests a new pad, the internal lock is kept while adding the pad
* Another thread (or the same one) requests the internal links of a pad (could
be that pad)... which also requires that lock.

That internal lock is not required when adding the pad to the element (which is
the last action when requesting a new pad). The fact it will be actually used
will be *after* the request pad function is released.

63ccf45395 inputselector: Ensure that events are pushed first on active pad
Making it less random and fixing a race in a GES test where we have
as pipeline:

```
videotestsrc ! output-selector name=s ! input-selector name=i s. ! timecodestamper ! i.
```

which we seek, leading to the seek reaching the video testsrc
without going through the timecodestamper and generating a buffer
even before timecodestamper gets the seek which means that its internal
state is wrong compared to the datastream it gets and attaches wrong
timecode metas.

9f5e65f0a2 input-selector: Let context queries pass through
By doing so GL source elements can successfully reuse the GL context and display
of downstream elements. This change fixes an issue in playbin when using
gltestsrc where the context query made by the source element would fail and the
source element would create a second (useless) GLDisplay.

89082272f8 inputselector: Always proxy position/duration query
active-pad switch causes reconfigure event with lock taken,
and upstream element might query the current position or duration
before returning the reconfigure event.
Meanwhile, gst_input_selector_get_linked_pad() is used to get srcpad
inside of default query handle, and it takes also lock.
Since inputselector is still locked by active-pad switch, and so the query
cannot be handled further.

4981e09bc7 inputselector: Wake other pads when selected goes EOS
Other pads that are waiting for the stream on the selected
pad to advance before they finish waiting themselves
should be given the chance to do so when the selected pad
goes EOS. Fixes problems where input streams can end up
waiting forever if the active stream goes EOS earlier than
their own end time.

b15e6f4bf0 inputselector: fix cached buffer leak in chain function
gst_selector_pad_chain() was popping cached buffers out of the queue without
freeing those. Make sure we don't steal the GstBuffer as the cached buffer ref
has been passed to the pad chain function.

This can be reproduced by running the
validate.file.playback.switch_subtitle_track_while_paused.test5_mkv scenario
with Valgrind.

6f24f4917d input-selector: Use segment-presence for running_time check
When determining whether the running_time of a pad can be
calculated, check if the segment is in TIME format instead
of using the 'active' field.

Since the latter is set through *any* activity, it's not a
reliable indicator of segment presence.

7a1ebbe0e3 input-selector: Remove obsolete 'block' signal
This signal blocks the input-selector with no means of unblocking
other than a state change back to READY. It seems this signal was
part of an old way of synchronously switching the selector,
together with the already-removed 'switch' signal.

Removing the signal is safe, as attempting to use it could only
end in deadlocks. Attempting to emit an unknown signal just causes
g_criticals.

ce663311e1 input-selector: Fix waiting on EOS
This apparently got broken by bc1ec4e. Since self->blocked is always
FALSE, gst_input_selector_wait never actually waits.

Using (!self->eos || self->blocked) && ... as the loop condition would
be incorrect as well, because then the other call to the function in
_chain would block until EOS, so the functions cannot be merged trivially.

Since blocking is obsolete, gst_input_selector_wait will get removed anyway.
As such, just inline the loop.

possibility to send its EOS event downstream anymore.
