* Move common effect processing code to wrapper method
- Introduce `processImpl` and `sleepImpl` methods, and adapt each effect
plugin to use them
- Use double for RMS out sum in Compressor and LOMM
- Run `checkGate` for GranularPitchShifterEffect
- Minor changes to LadspaEffect
- Remove dynamic allocations and VLAs from VstEffect's process method
- Some minor style/formatting fixes
* Fix VstEffect regression
* GranularPitchShifterEffect should not call `checkGate`
* Apply suggestions from code review
Co-authored-by: saker <sakertooth@gmail.com>
* Follow naming convention for local variables
* Add `MAXIMUM_BUFFER_SIZE` and use it in VstEffect
* Revert "GranularPitchShifterEffect should not call `checkGate`"
This reverts commit 67526f0ffe.
* VstEffect: Simplify setting "Don't Run" state
* Rename `sleepImpl` to `processBypassedImpl`
* Use `MAXIMUM_BUFFER_SIZE` in SetupDialog
* Pass `outSum` as out parameter; Fix LadspaEffect mutex
* Move outSum calculations to wrapper method
* Fix Linux build
* Oops
* Apply suggestions from code review
