* code review from michael

* Fix text problem in Vectorscope
Fix a problem with cutoff text in Vectorscope. During the constructor
call of `LedCheckBox` the method `LedCheckBox::onTextUpdated` is
triggered which sets a fixed size that fits the pixmap and the text.
After instantiating the two instances in `VecControlsDialog` the
constructor then set a minimum size which overrode the fixed size that
was previously set. This then led to text that was cutoff.

* Remove the struct StereoSample
Remove the struct `StereoSample`. Let `AudioEngine::getPeakValues` return a `sampleFrame` instead.
Adjust the calls in `Mixer` and `Oscilloscope`.
* Simplify AudioEngine::getPeakValues
* Remove surroundSampleFrame
Some code assumes that `surroundSampleFrame` is interchangeable with `sampleFrame`. Thus, if the line `#define LMMS_DISABLE_SURROUND` is commented out in `lmms_basics.h` then the code does not compile anymore because `surroundSampleFrame` now is defined to be an array with four values instead of two. There also does not seem to be any support for surround sound (four channels instead of two) in the application. The faders and mixers do not seem to support more that two channels and the instruments and effects all expect a `sampleFrame`, i.e. stereo channels. It therefore makes sense to remove the "feature" because it also hinders the improvement of `sampleFrame`, e.g. by making it a class with some convenience methods that act on `sampleFrame` instances.
All occurrences of `surroundSampleFrame` are replaced with `sampleFrame`.
The version of `BufferManager::clear` that takes a `surroundSampleFrame` is removed completely.
The define `SURROUND_CHANNELS` is removed. All its occurrences are replaced with `DEFAULT_CHANNELS`.
Most of the audio devices classes, i.e. classes that inherit from `AudioDevice`, now clamp the configuration parameter between two values of `DEFAULT_CHANNELS`. This can be improved/streamlined later.
`BYTES_PER_SURROUND_FRAME` has been removed as it was not used anywhere anyway.
* Make sampleFrame a class
Make `sampleFrame` a class with several convenience methods. As a first step and demonstration adjust the follow methods to make use of the new functionality:
* `AudioEngine::getPeakValues`: Much more concise now.
* `lmms::MixHelpers::sanitize`: Better structure, better readable, less dereferencing and juggling with indices.
* `AddOp`, `AddMultipliedOp`, `multiply`: Make use of operators. Might become superfluous in the future.
* More operators and methods for sampleFrame
Add some more operators and methods to `sampleFrame`:
* Constructor which initializes both channels from a single sample value
* Assignment operator from a single sample value
* Addition/multiplication operators
* Scalar product
Adjust some more plugins to the new functionality of `sampleFrame`.
* Adjust DelayEffect to methods in sampleFrame
* Use composition instead of inheritance
Using inheritance was the quickest way to enable adding methods to `sampleFrame` without having to reimpement much of `std::array`s interface.
This is changed with this commit. The array is now a member of `sampleFrame` and the interface is extended with the necessary methods `data` and the index operator.
An `average` method was added so that no iterators need to be implemented (see changes in `SampleWaveform.cpp`).
* Apply suggestions from code review
Apply Veratil's suggestions from the code review

* Fix warnings: zeroing non-trivial type
Fix several warnings of the following form:
Warnung: »void* memset(void*, int, size_t)« Säubern eines Objekts von nichttrivialem Typ »class lmms::sampleFrame«; use assignment or value-initialization instead [-Wclass-memaccess]
* Remove unnecessary reinterpret_casts
Remove some unnecessary reinterpret_casts with regards to `sampleFrame` buffers.
`PlayHandle::m_playHandleBuffer` already is a `sampleFrame*` and does not need a reinterpret_cast anymore.
In `LadspaEffect::processAudioBuffer` the `QVarLengthArray` is now directly initialized as an array of `sampleFrame` instances.
I guess in both places the `sampleFrame` previously was a `surroundSampleFrame` which has been removed.
* Clean up zeroSampleFrames code
* Fix warnings in RemotePlugin
Fix some warnings related to calls to `memcpy` in conjunction with`sampleFrame` which is now a class.
Add the helper functions `copyToSampleFrames` and `copyFromSampleFrames` and use them. The first function copies data from a `float` buffer into a `sampleFrame` buffer and the second copies vice versa.
* Rename "sampleFrame" to "SampleFrame"
Uppercase the name of `sampleFrame` so that it uses UpperCamelCase convention.
* Move SampleFrame into its own file
Move the class `SampleFrame` into its own class and remove it from `lmms_basics.h`.
Add forward includes to all headers where possible or include the `SampleFrame` header if it's not just referenced but used.
Add include to all cpp files where necessary.
It's a bit surprising that the `SampleFrame` header does not need to be included much more often in the implementation/cpp files. This is an indicator that it seems to be included via an include chain that at one point includes one of the headers where an include instead of a forward declaration had to be added in this commit.
* Return reference for += and *=
Return a reference for the compound assignment operators `+=` and `-=`.
* Explicit float constructor
Make the constructor that takes a `float` explicit.
Remove the assignment operator that takes a `float`. Clients must use the
explicit `float` constructor and assign the result.
Adjust the code in "BitInvader" accordingly.
* Use std::fill in zeroSampleFrames
* Use zeroSampleFrames in sanitize
* Replace max with absMax
Replace `SampleFrame::max` with `SampleFrame::absMax`.
Use `absMax` in `DelayEffect::processAudioBuffer`. This should also fix
a buggy implementation of the peak computation.
Add the function `getAbsPeakValues`. It computes the absolute peak
values for a buffer.
Remove `AudioEngine::getPeakValues`. It's not really the business of the
audio engine. Let `Mixer` and `Oscilloscope` use `getAbsPeakValues`.
* Replace scalarProduct
Replace the rather mathematical method `scalarProduct` with
`sumOfSquaredAmplitudes`. It was always called on itself anyway.
* Remove comment/TODO
* Simplify sanitize
Simplify the `sanitize` function by getting rid of the `bool found` and
by zeroing the buffer as soon as a problem is found.
* Put pointer symbols next to type
* Code review adjustments
* Remove "#pragme once"
* Adjust name of include guard
* Remove superfluous includes (leftovers from previous code changes)

Adjust and rename the function `pointSize` so that it sets the font size in pixels. Rename `pointSize` to `adjustedToPixelSize` because that's what it does now. It returns a font adjusted to a given pixel size. Rename `fontPointer` to `font` because it's not a pointer but a copy. Rename `fontSize` to simply `size`.
This works if the intended model is that users use global fractional scaling. In that case pixel sized fonts are also scaled so that they should stay legible for different screen sizes and pixel densities.
## Adjust plugins with regards to adjustedToPixelSize
Adjust the plugins with regards to the use of `adjustedToPixelSize`.
Remove the explicit setting of the font size of combo boxes in the following places to make the combo boxes consistent:
* `AudioFileProcessorView.cpp`
* `DualFilterControlDialog.cpp`
* `Monstro.cpp` (does not even seem to use text)
* `Mallets.cpp`
Remove calls to `adjustedToPixelSize` in the following places because they can deal with different font sizes:
* `LadspaBrowser.cpp`
Set an explicit point sized font size for the "Show GUI" button in `ZynAddSubFx.cpp`
Increase the font size of the buttons in the Vestige plugin and reduce code repetition by introducing a single variable for the font size.
I was not able to find out where the font in `VstEffectControlDialog.cpp` is shown. So it is left as is for now.
## Adjust the font sizes in the area of GUI editors and instruments.
Increase the font size to 10 pixels in the following places:
* Effect view: "Controls" button and the display of the effect name at the bottom
* Automation editor: Min and max value display to the left of the editor
* InstrumentFunctionViews: Labels "Chord:", "Direction:" and "Mode:"
* InstrumentMidiIOView: Message display "Specify the velocity normalization base for MIDI-based instruments at 100% note velocity."
* InstrumentSoundShapingView: Message display "Envelopes, LFOs and filters are not supported by the current instrument."
* InstrumentTuningView: Message display "Enables the use of global transposition"
Increase the font size to 12 pixels in the mixer channel view, i.e. the display of the channel name.
Render messages in system font size in the following areas because there should be enough space for almost all sizes:
* Automation editor: Message display "Please open an automation clip by double-clicking on it!"
* Piano roll: Message display "Please open a clip by double-clicking on it!"
Use the application font for the line edit that can be used to change the instrument name.
Remove overrides which explicitly set the font size for LED check boxes in:
* EnvelopeAndLfoView: Labels "FREQ x 100" and "MODULATE ENV AMOUNT"
Remove overrides which explicitly set the font size for combo boxes in:
* InstrumentSoundShapingView: Filter combo box
## Adjust font sizes in widgets
Adjust the font sizes in the area of the custom GUI widgets.
Increase and unify the pixel font size to 10 pixels in the following classes:
* `ComboBox`
* `GroupBox`
* `Knob`
* `LcdFloatSpinBox`
* `LcdWidget`
* `LedCheckBox`
* `Oscilloscope`: Display of "Click to enable"
* `TabWidget`
Shorten the text in `EnvelopeAndLfoView` from "MODULATE ENV AMOUNT" to "MOD ENV AMOUNT" to make it fit with the new font size of `LedCheckBox`.
Remove the setting of the font size in pixels from `MeterDialog` because it's displayed in a layout and can accommodate all font sizes. Note: the dialog can be triggered from a LADSPA plugin with tempo sync, e.g. "Allpass delay line". Right click on the time parameter and select "Tempo Sync > Custom..." from the context menu.
Remove the setting of the font size in `TabBar` as none of the added `TabButton` instances displays text in the first place.
Remove the setting of the font size in `TabWidget::addTab` because the font size is already set in the constructor. It would be an unexpected size effect of setting a tab anyway. Remove a duplicate call to setting the font size in `TabWidget::paintEvent`.
Remove unnecessary includes of `gui_templates.h` wherever this is possible now.
## Direct use of setPixelSize
Directly use `setPixelSize` when drawing the "Note Velocity" and "Note Panning" strings as they will likely never be drawn using point sizes.

No functional changes! No changes to savefiles/presets!
Fixes casing of everything that is currently lowercase but should
be uppercase.
Fixes also some other plugin strings, especially:
* opl2 -> OpulenZ (see 289887f4fc)
* calf -> veal (see ae291e0709)
* ladspa_effect -> LadspaEffect (see 9c9372f0c8)
* remove flp_import (see 2d1813fb64)
* Update ringbuffer submodule to fix includes
* Remove cyclic includes
* Remove Qt include prefixes
* Include C++ versions of C headers
E.g.: assert.h -> cassert
* Move CLIP_BORDER_WIDTH into ClipView
This allows to remove includes to TrackView.h in ClipView cpp files.
* Elliminate useless includes
This improves the include structure by elliminating includes that are
not used. Most of this was done by using `include-what-you-use` with
`CMAKE_C_INCLUDE_WHAT_YOU_USE` and `CMAKE_CXX_INCLUDE_WHAT_YOU_USE`
set to (broken down here):
```
include-what-you-use;

* `assert` (redefinition) -> using `NDEBUG` instead, which standard `assert` respects.
* `powf` (C stdlib symbol clash) -> removed and all expansions replaced with calls to `std::pow`.
* `exp10` (nonstandard function symbol clash) -> removed and all expansions replaced with calls to `std::pow`.
* `PATH_DEV_DSP` -> File-scope QString of identical name and value.
* `VST_SNC_SHM_KEY_FILE` -> constexpr char* with identical name and value.
* `MM_ALLOC` and `MM_FREE` -> Functions with identical name and implementation.
* `INVAL`, `OUTVAL`, etc. for automation nodes -> Functions with identical names and implementations.
* BandLimitedWave.h: All integer constant macros replaced with constexpr ints of same name and value.
* `FAST_RAND_MAX` -> constexpr int of same name and value.
* `QSTR_TO_STDSTR` -> Function with identical name and equivalent implementation.
* `CCONST` -> constexpr function template with identical name and implementation.
* `F_OPEN_UTF8` -> Function with identical name and equivalent implementation.
* `LADSPA_PATH_SEPARATOR` -> constexpr char with identical name and value.
* `UI_CTRL_KEY` -> constexpr char* with identical name and value.
* `ALIGN_SIZE` -> Renamed to `LMMS_ALIGN_SIZE` and converted from a macro to a constexpr size_t.
* `JACK_MIDI_BUFFER_MAX` -> constexpr size_t with identical name and value.
* versioninfo.h: `PLATFORM`, `MACHINE` and `COMPILER_VERSION` -> prefixed with `LMMS_BUILDCONF_` and converted from macros to constexpr char* literals.
* Header guard _OSCILLOSCOPE -> renamed to OSCILLOSCOPE_H
* Header guard _TIME_DISPLAY_WIDGET -> renamed to TIME_DISPLAY_WIDGET_H
* C-style typecasts in DrumSynth.cpp have been replaced with `static_cast`.
* constexpr numerical constants are initialized with assignment notation instead of curly brace intializers.
* In portsmf, `Alg_seq::operator[]` will throw an exception instead of returning null if the operator index is out of range.
Additionally, in many places, global constants that were declared as `const T foo = bar;` were changed from const to constexpr, leaving them const and making them potentially evaluable at compile time.
Some macros that only appeared in single source files and were unused in those files have been removed entirely.
Fixes bugs where during project loading (observed with VST effects), empty
widgets and sub-windows would be left floating around. These were caused by
inconsistencies between the way VST UIs were created when loading a project
and when adding an effect in an existing project. In some situations, this
caused createUI to be called twice, leaving over multiple empty widgets.
This commit refactors some code in order to avoid creating unnecessary sub-
windows, which aren't needed with VST effects, but were still created,
usually being invisible. All sub-window related code was moved out of
VstPlugin into vestige.cpp, which is the only place where sub-window VSTs
are actually used. A new sub-class of VstPlugin, VstInstrumentPlugin, now
handles VST sub-windows and is used by vestigeInstrument.
"guivisible" attribute loading was moved out of VstPlugin as well and is
now done in VstEffectControls' and vestigeInstrument's loadSettings method
respectively. This causes some minor code duplication unfortunately.
Closes#4110
