3cc45d5a36 subparse: Fix non-closed tag handling.
Unclear what the goal was, but we could end up reading way past the next_tag.

Instead just move everything from after the end tag ('>') to the next_tag.

1fff4ef635 decodebin3: fix EOS event sequence
See docs:
https://gstreamer.freedesktop.org/documentation/additional/design/seqnums.html?gi-language=c#seqnums-sequence-numbers

Per docs:
When a sink element receives an EOS event and creates a new EOS
message to post, it should copy the seqnum from the event to the
message because the EOS message is a consequence of the EOS event
being received.

We would check the wrong string (rest of line rather than element)

also has atrocious performance with certain strings like the garbled
nonsense clusterfuzz feeds us, which might cause discoverer to time
out when processing garbled SAMI files.

759321f7bc playbin3: Configure combiner on pad-added if needed
When collection is updated, decodebin3 exposes pad first and then
streams-selected message is posted.
The condition can cause a situation where playbin3 links non-existing
combiner/playsink pads (since streams-selected is not posted yet) with
new decodebin output pad. This commit will re-check selected/active
streams condition on pad-added and reconfigure output if needed.

69b205613f videorate: fix assertion when pushing last and only buffer without duration
Fixing this pipeline:
  gst-launch-1.0 filesrc location=sample.png ! pngdec ! videorate ! fakesink

- videorate receives a single buffer with pts = 0, duration = invalid;
- then it receives eos triggering this buffer to be pushed downstream;
- the pushing code was assuming that a duration was set, which is
  impossible as we received a single buffer and no output framerate was
  set either. So the best we can do is to push the buffer without
  duration.

7f377898f7 playsink: Fix reconfiguration after removing text_sink
If we previously had subtitles coming in, the video
may be chained through a text overlay block. Before,
the code would end up trying to link pads that were
already linked and video would not get reconnected
properly.

To fix that, make sure that the candidate
pads are actually unlinked first. If a textoverlay
is present and no longer needed, it will be cleaned
up later in the reconfiguration sequence.

5a074a11f9 playsink: Complete reconfiguration on pad release.
Requesting a new pad can start a reconfiguration cycle, where
playsink will block all input pads and wait for data on them
before doing internal reconfiguration. If a pad is released,
that reconfiguration might never trigger because it's now waiting
for a pad that doesn't exist any more.

In that case, complete the reconfiguration on pad release.

6d7dc93a45 uridecodebin3: Nullify current item after all play items are freed.
There's a potential race condition with this sort of pipelines on
certain systems (depends on the processing load):

GST_DEBUG_DUMP_DOT_DIR=/tmp \
gst-launch-1.0 uridecodebin3 uri=file://stream.mp4 ! glupload ! \
glimagesink --gst-debug=*:4

Right after the pipeline passes from PAUSED to READY, bin_to_dot_file
dumps uridecodebin3 properties, but current uri and suburi might be
already freed, causing a potential use-after-freed.

This patch makes NULL the current item right after all the play items
are freed.
