c71805c565 downloadbuffer: close file before trying to remove
On Windows, the file handles must be closed before you can delete a file.
Also, it would cause an error if you try to close an already closed handle.

4ad1c8b7c9 multiqueue: Ensure peer pad exists when iterating internal links
The pads can be NULL when we're racing with pad removal, e.g. when the
pads get removed between `gst_pad_iterate_internal_links` acquiring the
parent element and `gst_multi_queue_iterate_internal_links` locking the
multiqueue.

4eef67cc7e queue2: Refuse all serialized queries when posting buffering messages
When posting buffering messages there are no safe places or timing to avoid
deadlocks.

Previously the code was trying to be "smart" by only forwarding serialized
queries if the queue was empty ... but that could happen when queue2 hadn't yet
posted a 100% buffering message. Meaning the pipeline might be paused and
pushing a serialized query downstream might never complete.

Therefore let's completely disable forwarding of serialized queries when
`queue2` is used as a buffering element (meaning `ALLOCATION` and `DRAIN`
queries).

69e6cd773a clocksync: Add a new property "sync-to-first" for automatic ts-offset setup
Add a new property so that clocksync can setup "ts-offset" value
based on the first buffer and pipeline's running time when the
first arrived. Newly update "ts-offset" in this case would be
a value that allows outputting the first buffer without clock waiting.

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.

8e670a23b0 queue2: Defer downstream bitrate query to the streaming thread.
When we want to perform a downstream bitrate query, just
set the reconfigure flag on the srcpad and get the streaming
thread to do it. That avoids emitting a downstream query
when receiving the upstream RECONFIGURE event - which can
lead to deadlocks if downstream is sending the event from
within a lock - e.g. input-selector.

If querying the downstream bitrate changes the cached
value, then make sure to update our buffering state
and potentially post a BUFFERING message to the application.

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.

07fcd4d1b5 queue2: don't post unnecessary buffering message, refine locking
This is a follow up to review comments in !297

+ The posting of the buffering message in READY_TO_PAUSED isn't
  needed, removing it made the test fail, but the correct fix
  was simply to link elements together

+ Move code to relock the queue and set last_posted_buffering_percent
  and percent_changed inside the buffering_post_lock in create_write().
  This makes locking consistent with post_buffering()

6d4ad80b82 queue2: Fix missing/dropped buffering messages at startup
This fixes a bug that occurs when an attempt is made to post a buffering
message before the queue2 was assigned a bus. One common situation where
this happens is when the use-buffering property is set to TRUE before the
queue2 was added to a bin.

If the result of gst_element_post_message() is not checked, and the
aforementioned situation occurs, then last_posted_buffering_percent and
percent_changed will still be updated, as if posting the message succeeded.
Later attempts to post again will not do anything because the code then
assumes that a message with the same percentage was previously posted
successfully and posting again is redundant.

Updating these variables only if posting succeed and explicitely
posting a buffering message in the READY->PAUSED state change ensure that
a buffering message is posted as early as possible.

Making it less random and fixing a race in a GES test where we have

```
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.
