* Enable configuration of input device for SDL
Up to now the SDL audio driver attempted to use the default recording
device. This might not be what users want or expect, especially since the
actually used device is not visible anywhere. So if recording does not
work for the users they have no way to find out what's wrong.
Extend the settings screen of the SDL driver with a combo box that allows
to select the input device to be used. Store the selected device name in
a new attribute called "inputdevice" in the "audiosdl" section of the
configuration file.
Use the information from the configuration when attempting to inialize
the input device. Fall back to the default device if that does not work.
(cherry picked from commit 33139b9f4c)
* Provide a setting for system default input
Provide the setting "[System Default]" which instructs the SDL driver to
use the default device of the system as the input device. In the
configuration file this option is represented as an empty string. This
should play well with the current existing configuration of the users.
(cherry picked from commit 29c43c2bb6)
* Configuration of output device for SDL
Let users configure the output device that's used by the SDL driver.
Code-wise the implementation is very similar to the input device
configuration.
Use a `QComboBox` instead of a `QLineEdit` for `m_device` and rename it
to `m_playbackDeviceComboBox`.
Rename `s_defaultInputDevice` to `s_systemDefaultDevice` because it is
used in the context of playback and input devices.
(cherry picked from commit 1ab45e4994)
* Ensure label visibility
Make sure that labels are always shown by setting the row wrap policy of
the form layout to wrap long rows.
(cherry picked from commit a123d0e3cb)
* Rename "Device"
Rename "Device" to "Playback device" to make clear what the setting
refers to.
(cherry picked from commit 1f0cda4983)
* Remove repeated strings
Introduce const expressions to get rid of repeated strings with a risk
of typos.
(cherry picked from commit f9ea9705b8)
* Apply some more changes
Apply some more changes that have been made to `AudioSdl` in the
recording branch.
* Conditional ternary operator
Also use a conditional ternary operator for the input device setup.
* Methods for population of combo boxes
Move the population of the input and playback device combo boxes into
the methods `populatePlaybackDeviceComboBox` and
`populateInputDeviceComboBox`.
* Sort devices in combo box
Sort the devices names alphabetically in the input and playback combo
boxes. The default devices is always shown as the first entry.
* Code review fixes
Use `AudioDeviceSetupWidget` instead of `QObject` to translate "[System
Default]".
Fix copy/paste error in comment.
* Simplify some constexpr statements
* Fix#5851: Implement `EffectRackView::sizeHint()`
This fixes `EffectRackView` to have a permanent size hint instead of
resizing the widget once in `InstrumentTrackWindow`. The size hint tells
the `InstrumentTrackWindow` to not increase with a growing number of
effects in the `EffectRackView`.

Introduce a method which checks if a file that's loaded has the LADSPA
controls saved in an old format that was written with a version before
commit e99efd541a.
The method is run at the end so that problems in all file versions are
detected. If a real upgrade was to be implemented it would have to run
between `DataFile::upgrade_0_4_0_rc2` and `DataFile::upgrade_1_0_99`.
See #5738 for more details.
If a problematic file is encountered a warning dialog that provides the number of affected LADSPA plugins is shown.

Defines `fpp_t` and `f_cnt_t` to be of `size_t` within `lmms_basics.h`. Most of the codebase used `fpp_t` to represent the size of an array of sample frames, which is incorrect, given that `fpp_t` was only 16 bits when sizes greater than 32767 are very possible. `f_cnt_t` was defined as `size_t` as well for consistency.

About the PR:
* We use "blocked" as an abstract term, when there may be different reasons
* If there is a concrete reason, we use a more concrete word like "unstable"
or "not useful"
* Double negations like "don't block" or "block unstable" are avoided
Besides this, this PR
* Lets `Lv2Manager` hide the full `std::set` of plugin URIs
* Fixes occurences of "BuffersizeLessThan32" - it is less or equal
* Moves `enableBlockedPlugins` from Engine to `ConfigManager`
* Adds "Show Hidden Content Dialogue"
* Update FileBrowser.cpp
* Automatically rearrange layout to fit check boxes
* check if files are hidden in a cross platform manner
* put the hidden files checkbox below the user and factory check boxes at all times
* removed layout rearrangement code
* moved checkbox code to FileBrowser
* Removed unused include
* Cleanup in FileBrowser
Move the method `addContentCheckBox` to the other private methods.
Remove the method parameters because it can use the members.
Remove the conditional when adding the "Hidden content" checkbox because
it was always true.

* 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)

## Add support for "factorysample:" prefix
Add support to upgrade files with `src` tags that are prefixed with "factorysample:".
## Fix "bassloopes" typo
Fix projects that still reference files with the typo "bassloopes" in their name.
The upgrade is implemented in its own method because it is unrelated to the BPM renaming even if it is technically very similar in its solution.
Introduce the helper method `mapSrcAttributeInElementsWithResources` which replaces the `src` attribute in elements with resources (samples and AFP) if it can be found in a map.
Add peak indicators to the mixer strips. They show the maximum peak value
that was observed and can be reset by clicking on them.
## Implementation details
The implementation works via a signal/slot mechanism. The `Fader` class
has a new signal `peakChanged` which reports peak values as
amplifications. A new class `PeakIndicator` is added which has a slot
`updatePeak` which is connected to the new signal in `Fader`.
The `PeakIndicator` inherits from `QLabel` and mainly deals with updating
the label text from the current peak value.
Add a `PeakIndicator` instance to `MixerChannelView`. Add a `reset`
method to `MixerChannelView` so that the mixer channel can be reset on
the loading of new projects, etc. The current implementation resets the
peak indicator back to -inf dbFS. The `reset` method is called in
`MixerView::clear`.
Remove the clamping in `Fader::setPeak` so that all peaks are reported.
Emit the new signal if the peak changes.

Only show the recording widget in the sample clip if the audio engine has
a device configured that can capture audio. For simplicity of the code,
i.e. no nullptr checks, the widget is always created but only shown if
capture capabilities are available.
Rename the context menu entry "Set/clear record" to "Toggle record" and
only enable it if capture is possible.
In `SampleClipView` the test for the availability of a capture device is
abstracted behind the helper method `recordingCapabilitiesAvailable`.
Technical details
------------------
Add the method `captureDeviceAvailable` to `AudioEngine` because clients
should not be concerned with driver details. Drivers should mostly be
used by the audio engine and therefore hidden to clients. Add a private
`const` version of the method `audioDev` so that `captureDeviceAvailable`
can be implemented in a `const` correct way.
Use `captureDeviceAvailable` in the constructor of `SongEditorWindow`.
Make the option to record samples more prominent by providing a pixmap
button that is always shown and that can be used to turn recording on or
off. The corresponding widget which constitutes of the button and a label
is always positioned at the bottom left of the sample clip.
Technical details
------------------
The recording widget is built in the private method `buildRecordWidget`.
The method `adjustRecordWidget` is used to move the recording widget to
the correct position relative to the sample view. It is called after
construction and whenever the sample clip is resized (see `resizeEvent`).
Add the method `SampleClip::getRecordModel` so that the pixmap button can
be configured to act on it.
Let users configure the output device that's used by the SDL driver.
Code-wise the implementation is very similar to the input device
configuration.
Use a `QComboBox` instead of a `QLineEdit` for `m_device` and rename it
to `m_playbackDeviceComboBox`.
Rename `s_defaultInputDevice` to `s_systemDefaultDevice` because it is
used in the context of playback and input devices.
Provide the setting "[System Default]" which instructs the SDL driver to
use the default device of the system as the input device. In the
configuration file this option is represented as an empty string. This

Remove the clamping in `Fader::setPeak` so that all peaks are reported.
Emit the new signal if the peak changes.
* Added lines in between bars
* Changed bar lines to follow snap size
* Changed default zoom and quantization value
* Added constants for line widths
* Added QSS configuration for new grid line colors
* Tied line widths to QSS properties
* Changed default quantization to 1/4
* Removed clear() from destructor model
* Removed destructor in ComboBoxModel.h
* Changed member set/get functions to pass by value
* Updated signal connection with newer syntax
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).
Add the virtual method `Effect::onEnabledChanged` which can be overridden by effects so that they can react to state changes with regards to being enabled or bypassed. The call of this methods is connected to state changes of the enabled model in the constructor of `Effect`.
Implement the method in `DualFilterEffect` by resetting the history of the two filters. This is done to prevent pops that have been reported in #4612.
Check if a non-empty buffer was loaded and only set the sample clip if that's the case.
## Other changes
Move setting the song to modified towards the core in the context of `SampleClip`. Previously the `SampleClipView` did this but it's none of it's business.
Introduce `SampleClip::changeLengthToSampleLength` which changes the length of the clip to the length of the sample. This was also previously done by the view which is again the wrong place to do the necessary calculations. An unnecessary `static_cast` was removed while carrying over the code.
Add the method `SampleClip::hasSampleFileLoaded` which checks if the loaded sample corresponds to a given file name.
Fix code formatting.
