* Fix double -> float truncation, DrumSynth fix
I mistakenly introduced a bug in my recent PR regarding template
constants, in which a -1 that was supposed to appear outside of an abs()
instead was moved inside it, screwing up the generated waveform. I fixed
that and also simplified the function by factoring out the phase domain
wrapping using the new `ediv()` function from this PR. It should behave
how it's supposed to now... assuming all my parentheses are in the right
place lol

It should all work for negative phase inputs as well. If I end up

* Simplify DrumSynth triangle waveform
This reuses more work and is also a lot more easy to visualize.
It's probably a meaningless micro-optimization, but it might be worth changing it back to a switch-case and just calculating ph_tau and saw01 at the beginning of the function in all code paths, even if it goes unused for the first two cases. Guess I'll see if anybody has strong opinions about it.

* 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)

Oversampling can have many different effects to the audio signal such as latency, phase issues, clipping, smearing, etc, so this should really be an option on a per-plugin basis, not globally across all of LMMS (which, in some places, shouldn't really need to oversample at all but were oversampled anyways).
Make instruments report their release time in milliseconds so that it becomes independent of the sample rate and sounds the same at any sample rate.
Technically this is done by removing the virtual keyword from `desiredReleaseFrames` so that it cannot be overridden anymore. The method now only serves to compute the number of frames from the given release time in milliseconds.
A new virtual method `desiredReleaseTimeMs` is added which instruments can override. The default returns 0 ms just like the default implementation previously returned 0 frames.
The method `computeReleaseTimeMsByFrameCount` is added for instruments that still use a hard coded release in frames. As of now this is only `SidInstrument`.
Add the helper method `getSampleRate` to `Instrument`.
Adjust several instruments to report their release times in milliseconds. The times are computed by taking the release in frames and assuming a sample rate of 44.1 kHz. In most cases the times are rounded to a "nice" next value, e.g.:
* 64 frames -> 1.5 ms (66 frames)
* 128 frames -> 3.0 ms (132 frames)
* 512 frames -> 12. ms (529 frames)
* 1000 frames -> 23 ms (1014 samples)
In parentheses the number of frames are shown which result from the rounded number of milliseconds when converted back assuming a sample rate of 44.1 kHz. The difference should not be noticeable in existing projects.
Remove the overrides for instruments that return the same value as the base class `Instrument` anyway. These are:
* GigPlayer
* Lb302
* Sf2Player
For `MonstroInstrument` the implementation is adjusted to behave in a very similar way. First the maximum of the envelope release times is computed. These are already available in milliseconds. Then the maximum of that value and 1.5 ms is taken and returned as the result.

Remove identical calls to `InstrumentTrack::processAudioBuffer` which appear in the overridden implementations of `Instrument::play` and `Instrument::playNotes`. Instead the call to `processAudioBuffer` has been moved into `InstrumentPlayHandle::play` and `InstrumentTrack::playNote`. These two methods call the aforementioned methods of `Instrument`. Especially in the case of `InstrumentTrack::playNote` the previous implementation resulted in some unncessary "ping pong" where `InstrumentTrack` called a method on an `Instrument` which then in turn called a method on `InstrumentTrack`. And this was done in almost every instrument.
In `InstrumentTrack::playNote` an additional check was added which only calls `processAudioBuffer` if the buffer is not `nullptr`. The reason is that under certain circumstances `PlayHandle::doProcessing` calls the `play` method by explicitly passing a `nullptr` as the buffer. This behavior was added with commit 7bc97f5d5b. Because it is unknown if this was done for some side effects the code was adjusted so that it behaves identical in this case.
Move the complex implementation for `InstrumentPlayHandle::play` and `InstrumentPlayHandle::isFromTrack` into the cpp file and optimize the includes.
This PR places all LMMS symbols into namespaces to eliminate any potential future name collisions between LMMS and third-party modules.
Also, this PR changes back `LmmsCore` to `Engine`, reverting c519921306 .
