When there's no main window (initial setup, no transient parent),
preset a normal window listed in the task-bar.
The duality the Engine Dialog being used as Ardour-WM managed non-modal
Window (Menu > A/M Setup) and modal Dialog (AudioEngineSetupRequired)
complicates this a bit.
The default for export-silence-threshold is -INFINITY, written
as "-inf" (by cfgtool) into system_config. Yet parsing the config using
a std::stringstream results in "0" (due to bugs in various libc++).
This will work the same as the existing binding with a Region Selection and
will also duplicate ranges in range selection mode.
Also add multi-duplicate editor action and use that for the default
multi-duplicate action, which will work the same in Object Selection/Grab Mode
but also supports Multi Duplicate of Range Selections....well it would if
that functionality worked correctly.
The duplicate and duplicate-multi region actions still have to exist to be used
in the Region menu as they should only be sensitive if there is a Region
selection which would not be the case if the editor actions were used.
Resolves: #7153
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
Should resolve: #6412
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.
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.

All float values defined in the CONFIG_VARIABLE macro seem like they are cast
to at some stage before writing (another issue that needs addressing). The
default value for export-silence-threshold (-INFINITY) is converted to a value
of 0 and as a result nothing is exported with trim enabled.
Use the same fixed silence threshold as Mixbus until proper bounds checking and
GUI is in place.
