After EOS, it is possible for a pad to be resetted by sending
either a STREAM_START or SEGMENT event
Mimic the same behaviour when receiving STREAM_START/SEGMENT events
in queue if we are EOS'd

Have to modify libcheck header a bit to avoid warnings
about duplicate 'extern extern'.
Also needs some additions to the libcheck meson.build file
to define CK_EXP_DLL when building the static libcheck.
for vararg parameters. Vararg functions are not introspectable anyway,
so might just as well mark them as '(skip)' while we're at it.

When queue-like elements are in "EOS" situation (received GST_FLOW_EOS
from downstream or EOS was pushed), they drain buffers/events that
wouldn't be processed anyway and let through events that might
modify the EOS situation.
Previously only GST_EVENT_EOS and GST_EVENT_SEGMENT events were let
through, but we also need to allow GST_EVENT_STREAM_START to go
through since it resets the EOS state of pads since 1.6

When downstream returns NOT_LINKED, we return the buffering level
as being 100%.
Since the queue is no longer being consumed/used downstream, we
want applications to essentially "ignore" this queue for buffering
purposes.
If other streams are still being used, those stream buffering levels
will be used. If none are used, upstream will post an error message
on the bus indicating no streams are used.

Without the former, event changes (e.g. setting a pad offset) does not
take effect for the current buffer but only for the next one. Without
the latter, non-blocking event probes would not see any updated events
yet.
This stores debug logs in memory per thread and uses up to a
configurable amount of bytes per thread for the logs. Inactive threads
are timed out after a configurable amount of time.

... and use the biggest interleave value among streaming threads.
This is to optimize multiqueue size adaptation on adaptive streaming
use case with "use-interleave" property.

Add back function guard that checks the refcount in a read-only
operation first, and bail out without modifying the passed-in
memory if it's clearly not a valid mini object. Otherwise we
probably cause more harm than good. We keep the second sanity
check based on the 'real refcount' at the time of the unref
around for now too.

buffer is not unreferened if preroll failed
:Detailed Notes:
- Problem : video freeze when switching from pause to 1/2-FF repeatedly
- RootCause : buffer leaks in basesink
- Solution : unref the buffer if prerolled failed
:Testing Preformed:
How to Test :
pause -> 1/2 FF -> resume -> pause -> 1/2 FF ...

Holding this lock on live source prevents the source from changing
the caps in ::create() without risking a deadlock. This has consequences
as the LIVE_LOCK was replacing the STREAM_LOCK in many situation. As a
side effect:
- We no longer need to unlock when doing play/pause as the LIVE_LOCK
isn't held. We then let the create() call finish, but will block if
the state have changed meanwhile. This has the benefit that
wait_preroll() calls in subclass is no longer needed.
- We no longer need to change the state to unlock, simplifying the
set_flushing() interface
- We need different handling for EOS depending if we are in push or pull
mode.
This patch also document the locking of each private class member and
the locking order.
