f41f84538a output-selector: Drop duplicated seek events
When we get a seek event on several source pads, we should drop
the duplicated ones as any element that has several srcpads (like
demuxers).

b63dd628d2 meson: Pass native: false to add_languages()
This is needed for cross-compiling without a build machine compiler
available. The option was added in 0.54, but we only need this in
Cerbero and it doesn't affect older versions so it should be ok.
Will just cause a spurious warning.

cb212c9fd7 identity: Handle seeking with single_segment=True
Identity was ignoring seek and flush events even when using
a single segment. In the end it means that we couldn't compute
buffers running-time and stream time after seeks.

This commits adds support for flushing seeks only as I have no idea
what to do for non flushing ones.

b517b59171 identity,clocksync: Fix timestamping inside single segment in reverse playback
In reverse playback, buffers are played back from buffer.stop
(buffer.pts + buffer.duration) to buffer.pts running times which
mean that we need to use the buffer end running time as a buffer
timestsamp, not the buffer pts when using a single segment in reverse
playback.

This is now being tested in
`validate.test.identity.reverse_single_segment`

39b9cc554c basesink: Fix clock synchronization running time in reverse playback
In reverse playback, buffers have to be displayed at buffer.stop running
time, otherwise a same set of buffer can't be displayed in the exact opposite
order to forward playback.

For example, seeking a video stream at 1fps with start=0, stop=5s, rate=1.0

will display the following buffers:

  b0.pts = 0s, b0.duration = 1s - at running time = 0s
  b1.pts = 1s, b1.duration = 1s - at running time = 1s
  b2.pts = 2s, b2.duration = 1s - at running time = 2s
  b3.pts = 3s, b3.duration = 1s - at running time = 3s
  b4.pts = 4s, b4.duration = 1s - at running time = 4s
  <wait at EOS for 1second>

Now, playing that reverse with start=0, stop=5s, rate=1.0 has to display
the following buffers:

  b0.pts = 4s, b0.duration = 1s - at running time = 0s
  b1.pts = 3s, b1.duration = 1s - at running time = 1s
  b2.pts = 2s, b2.duration = 1s - at running time = 2s
  b3.pts = 1s, b3.duration = 1s - at running time = 3s
  b4.pts = 0s, b4.duration = 1s - at running time = 4s
  <wait at EOS for 1second>

With the previous code, it reproduced the following:

  b0.pts = 4s, b0.duration = 1s - at running time = 1s
  b1.pts = 3s, b1.duration = 1s - at running time = 2s
  b2.pts = 2s, b2.duration = 1s - at running time = 3s
  b3.pts = 1s, b3.duration = 1s - at running time = 4s
  b4.pts = 0s, b4.duration = 1s - at running time = 5s
  <NO WAIT AT EOS AND POST EOS RIGHT AWAY>

This is being tested with the `validate.launch_pipeline.sink.reverse_playback_clock_waits.*`
set of tests

4a025d77ac basesrc: Fix the way position is computed in reverse playback
In reverse playback, buffers are played back from buffer.stop
(buffer.pts + buffer.duration) to buffer.pts, which means that the
position after the buffer is consumed is buffer.pts, not buffer.pts -
buffer.duration.

Without that change, and when `automatic_eos` feature is on,
we were dropping the last buffers as marking the stream EOS one buffer
too soon.

This is now being tested extensively by GstValidate in the
`validate.test.clock_sync.*` set of tests.

0d1fe824e2 registrybinary: Don't call fclose() more than once
We must not retry fclose() on EINTR as POSIX states:

  After the call to fclose(), any use of stream results in undefined
  behavior.

We ensure above with fflush() and fsync() that everything is written out
so chances of running into EINTR are very low. Nonetheless assume that
the file can't be safely renamed, we'll just try again on the next
opportunity.

841fa7062e gstvalue: No longer store same-type intersection functions in table
The intersection function table is a legacy of 2005, when one could
register random intersection functions. This is no longer the case.

The only place where that table was used was:

* `gst_value_can_intersect()`, where it was already only used for identical
GType
* `gst_value_intersect()`, where the table iteration was insanely expensive

Instead this patch:
* Only stored intersection functions for *different* types (of which there are
only 4)
* Make gst_value_intersect directly call the same-type intersection functions
and only use the table if ever it doesn't match.
