Fix realtime export loudness normalization
TmpFileRt::get_samples_written() returns the number of
samples written *to disk*. It is only valid after the FileFlushed
signal is emitted.

This fixes an assert() with Limiter and Analyzer being configured
with a too low total sample-count, leading to an overflow in
the analysis graph array.

Revert "use -90dB as default threshold for silence trim during export, rather than -inf dB"
This reverts commit fe8418ffea,
which had no effect, since the default c'tor argument is not used.

Overhaul export loudness normalization
* Fix exporting multiple formats with different
  normalization settings or demo-noise settings
* Add true-peak limiter (based on x42-limiter dpl.lv2)
* Optionally use a limiter for loudness normalization
* Fall back to short-term loudness when normalizing
  material too short for integrating loudness.

gcc-11 compat, volatile atomic variables (1/2)
"While 'atomic' has a volatile qualifier, this is a historical
artifact and the pointer passed to it should not be volatile."

Furthermore "It is very important that all accesses to a
particular integer or pointer be performed using only this API"
(from https://developer.gnome.org/glib/2.68/glib-Atomic-Operations.html)

Hence initialization of atomic variables is changed to also use
this API, instead of directly initializing the value.

This also fixes a few cases where atomic variables were
accessed directly.

This still assert()s in debug builds. Since those plugins

bd52d4e328 Fix issues in export with trim enabled
A complete reimplementation of AudioGrapher::SilentTrimmer::process to support
trimming the beginning and end in the same processing block

Fix export with trim end enabled to actually trim silent frames

Only add silence to beginning or end of export data if data was written

568cf861f9 Rename AudioGrapher::SilentTrimmer method to reflect behaviour
Unlike many of the other uses of the term "frame" this is actually returning
the index to the first sample in the interleaved frame that contains
non-silence.

2c67e71e98 Always signal writing to file is complete at end of the export process
With end trim enabled, the only case that would successfully export was if
there was at least some samples above the silence threshold in the last export
processing block.

The issue was that the EndOfInput flag was not being passed to
AudioGrapher::SndFileWriter::process which would then call sf_write_sync and
emit the FileWritten signal to start post processing. Fix that by always
passing the EndOfInput flag in the last export process cycle.
