4fc4ad87d5 query: add a new bitrate query
Allows determining from downstream what the expected bitrate of a stream
may be which is useful in queue2 for setting time based limits when
upstream does not provide timing information.

Implement bitrate query handling in queue2

c4ccff7861 queue2: avoid ping-pong between 0% and 100% buffering messages
If upstream is pushing buffers larger than our limits, only 1 buffer
is ever in the queue at a time.  Once that single buffer has left the
queue, a 0% buffering message would be posted followed immediately by a
100% buffering message when the next buffer was inserted into the queue
a very short time later.  As per the recommendations, This would result
in the application pausing for a short while causing the appearance of
a short stutter.

The first step of a solution involves not posting a buffering message if
there is still data waiting on the sink pad for insertion into the queue.
This successfully drops the 0% messages from being posted however a
message is still posted on each transition to 100% when the new buffer
arrives resulting in a string of 100% buffering messages.  We silence
these by storing the last posted buffering percentage and only posting a
new message when it is different from or last posted message.

3eb334a7f9 typefind: Lower debug level of some output related to the URI query
It's not a warning if an URI doesn't have an extension, and it's also
not mandatory that sources have an URI or even answer the URI query.

127e211004 multiqueue: Don't clamp running times for position calculation
Since we use full signed running times, we no longer need to clamp
the buffer time.

This avoids having the position of single queues not advancing for
buffers that are out of segment and never waking up non-linked
streams (resulting in an apparent "deadlock").

98fabd2fa2 queue2: Reset result flow when retrying
If we ever get a GST_FLOW_EOS from downstream, we might retry
pushing new data. But if pushing that data doesn't return a
GstFlowReturn (such as pushing events), we would end up returning
the previous GstFlowReturn (i.e. EOS).

Not properly resetting it would cause cases where queue2 would
stop pushing on the first GstEvent stored (even if there is more
data contained within).

e975e0cae8 filesink: Remove buffer, deprecate line-buffer mode and don't use fflush()
fflush() has no effect because we use writev() directly, so fsync()
should be used instead which is actually flushing the kernel-side
buffers.

As a next step, a non-line-buffered buffering mode is to be added.

f03443f90c concat: Handle single-pad use-cases
When EOS reaches concat, it will switch to the next candidate as its
activate pad.

The problem arises when there is only one sinkpad, the "active" pad
becomes NULL. This results in concat becoming unusable after it receives
a *single* EOS on its single sinkpad.

If we detect there is a single sinkpad and there is no current active pad:
* If we are waiting (from selected sink event/buffer), become the current
  active pad.
* If there is a seek request, send it upstream. We don't switch the
  active_sinkpad property at that point in time, since the seek could
  fail. If the seek succeeds, the following SEGMENT (or STREAM_START)
  will cause the pad_wait() to elect that pad as the new active one.
* Flush events get forwarded

Otherwise we might try unscheduling a clock id (that does not exist
yet), then the streaming thread waits for id and the state change never
continues because the streaming thread is blocked.

Also shutting down and flushing and similar should return FLUSHING, not
EOS. The stream is not over, we're just not accepting any buffers
anymore.

e2f8dc0aef plugins: *queue* elements: Handle STREAM_START in EOS situation
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

4312119d16 queue2: Handle buffering levels on NOT_LINKED
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.
