555df9d614 plugins: Check return values of gst_buffer_map()
They can fail for various reasons.

For non-fatal cases (such as the dump feature of identiy and fakesink),
we just silently skip it.

For other cases post an error message.

fd253ab1ab Revert "queue2: add overrun signal"
This reverts commit 8ae8b2723d.

It's not used anymore by anything and was considered a bad idea in general.

c1f4920859 queue2: Add use-tags-bitrate property
The use-tags-bitrate property makes queue2 look at
tag events in the stream and extract a bitrate for the
stream to use when calculating a duration for buffers
that don't have one explicitly set.

This lets queue2 sensibly buffer to a time threshold
for any bytestream for which the general bitrate is known.

725a71ea0c queue2: Don't report 0% unless empty
When preparing a buffering message, don't report 0% if there
is any bytes left in the queue at all. We still have something
to push, so don't tell the app to start buffering - maybe
we'll get more data before actually running dry.

c55bfecc55 Revert "queue2: Process SEEKING query"
This caused problems with oggdemux when queue2 was
operating in queue mode and the souphttpsrc upstream
is not seekable because the server doesn't support
range requests. It would then still claim seekability
and then things go wrong from there.

This reverts commit 7b0b93dafe.

8d835ec400 queue2: percentage is relative to high-percent
When comparing percentage values, compare with 0-100 scale as it
has already been made relative to 0-high_percent, otherwise we mark
the queue as not buffering and report a 50% to the user. This leads to
a buffering stall as the user assumes the queue is still buffering but
it thinks it isn't.

ecf479e3d1 queue2: do not post buffering messages holding the lock
It might cause deadlocks to post messages while holding the queue2
lock. To avoid this a new boolean flag is set whenever a new
buffering percent is found. The message is posted after the lock
is released.

To make sure the buffering messages are posted in the right order, messages
are posted holding another lock. This prevents 2 threads trying to post
messages at the same time.

f3dd7937a2 queue2: fix event/preroll deadlock differently
The qlock is released between popping a buffer from the queue
and pushing it. When this buffer causes the sink to wait in
preroll, this lets a query see that the queue is empty, and
push the query then wait for it to be serviced. However, this
will not be done till after peroll, and this will thus block.
If upstream was waiting on buffering to reach 100% before
switching to PLAYING, a deadlock would ensue.

This had been fixed recently by failing queries when the
queue2 was buffering, but this happens to break some other
case (playbin on a local http server and matroska), while
this patch works for both.

We fix it by refusing the query when buffering, as per Wim's

6fa8edd6b0 queue2: Fix merging of ranges
Make a method to get the seeking threshold. If data is further away from
this threshold we want to perform a seek upstream.
When the current downloaded range can merge with the next range,
actually include the data of the next range into the current range
instead of discarding it. Also decide if we seek to the write position
of the merged range or continue reading.

4cb596ddd6 Update the buffering state before stalling for more data
In some cases the wait for more data was happening without updating
the buffering state, meaning the API user would not be able to notice
it should pause the pipeline and update UI to indicate that is the
case, the video would likely stutter instead.

c02081ca30 queue2: don't change global buffering state from within query handler
When a buffering query is handled it uses the get_buffering_percent()
function to get some statitics. Unfortunately this function also
calculates whether the queue should be buffering and adapts the
global queue2 state in case of state transitions from/to buffering
(including whether a buffering message was posted on the bus!).

This means that there is a race which can cause buffering messages
to never posted if the global state changes happen as a result of aa
query instead of resulting from bytes flowing in/out.

Spotted by Sjoerd Simons.

Change to only query state in get_buffering_percent() and update
state only in update_buffering().

2f78e96299 queue2: only block serialized query when it's safe
We must be certain that we don't cause a deadlock when blocking the serialized
queries. One such deadlock can happen when we are buffering and downstream is
blocked in preroll and a serialized query arrives. Downstream will not unblock
(and allow our query to execute) until we complete buffering and buffering will
not complete until we can answer the query..
