9ec6a02e13 task: do not resume when resume_receiver is cancelled
This could cause the state to go back to Started after
stop() was called, resulting in a panic in a subsequent
unprepare.

3f05e448d7 audioloudnorm: Allow more than 2 channels
There's no limitation of the number of channels in the code, so allow

666ec7d54d audiofx: Add audioloudnorm filter based on the ffmpeg af_loudnorm filter
This normalizes the loudness of an audio stream to a target loudness
with a given maximum peak based on EBU R128.

Conceptually it keeps a 3s lookahead for calculating the perceived
loudness and based on that calculates the gain required to reach the
target loudness. The calculated gains then go through a gaussian filter
for smoothening and are then applied to the audio in 100ms blocks. Each
of the 100ms blocks is then passed to a limiter filter to prevent going
above the maximum peak.

See http://k.ylo.ph/2016/04/04/loudnorm.html for some more details about
the algorithm.

It introduces 3s of latency and currently only works on 192kHz audio.
Using it with a different sample rate requires resampling before and
afterwards. The upsampling is required to calculate the true peak.

Other than the ffmpeg filter it currently does not support two-pass
processing but only one-pass/live processing.

Compared to the ffmpeg filter this code was refactored considerably and
the limiter implementation was fixed to actually work, as well as
various other bugs in different places that were fixed.

116cf9bd3c threadshare/*src: rework pause/flush_start/flush_stop
This commit fixes several issues with the `Ts*Src` elements.

The pause functions used cancel_task which breaks the Task loop at await
points. For some elements, this implies making sure no item is being lost.
Moreover, cancelling the Task also cancels downstream processing, which
makes it difficult to ensure elements can handle all cases.

This commit reimplements Task::pause which allows completing the running
loop iteration before pausing the loop.

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/277#note_439529

In the Paused state, incoming items were rejected by TsAppSrc and DataQueue.

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/277#note_438455

- FlushStart must engage items rejection and cancel the Task.
- FlushStop must purge the internal stream & accept items again.

If the task was cancelled, `push_prelude` could set `need_initial_events`
to `true` when the events weren't actually pushed yet.

TsAppSrc used to renew its internal channel which could cause Buffer loss
when transitionning Playing -> Paused -> Playing.

96cfcff4cf caption_frame_decode: rework API
* pop_on mode requires incrementing the frame timestamp until
  end_of_caption is encountered.

* caption_frame_decode now always updates the timestamp of the
  frame when the timestamp parameter != -1. This requires that callers
  only pass a valid timestamp when a new one is encountered, for
  example with SCC the timestamp at the start of the cue, then -1
  until the next new timestamp.

* A new enum member is added for the return value, LIBCAPTION_CLEAR.
  It allows the caller to determine that closed captions should not
  be displayed anymore, in order to finish the previous cue earlier
  than the start of the next cue.

0b240b829e threadshare/inputselector: fix tearing down
GstElementClass.release_pad() may be called after the element
has transitioned back to NULL, we need to keep our sink_pads
map around until then.

They should also not be affected by state transitions at all but only be
removed once the user does so or the element is destroyed, so they need
to live independent of the state.
