Add labeled controls for different types with a common base class

Implement a container for multiple equal groups of linked models and
suiting views. Such groups are suited for representing mono effects where each
Model occurs twice. A group provides Models for one mono processor and is
visually represented with a group box.

This concept is common for LADSPA and Lv2, and useful for any mono effect.

* Add "Open containing folder" (#5453)

Add functionality to open the containing folder of a file that's selected
in LMMS' file browser.

Technical details
Add a new private method openContainingFolder to FileBrowser. Add a new
action to the context menu of a selected file. This action in turn calls
the added method.

The current implementation of openContainingFolder delegates to
QDesktopServices::openUrl with the directory of the selected file. Please
note that this will only open the directory but not select the file as
this is much more complicated due to different implementations that are
needed for the different platforms (Linux/Windows/MacOS).

Using QDesktopServices::openUrl seems to be the most simple cross
platform way which uses functionality that's already available in Qt.

* Code review changes

Move openContainingFolder to the end of the method block.

Adjust FileBrowserTreeWidget::contextMenuEvent to the coding conventions
and also make the code more readable by splitting up some conditions.

Add comments to clarify as to why the member m_contextMenuItem is set to
nullptr at the end of the execution of contextMenuEvent. Please note
that this implementation is not exception safe and should be changed in
the future, e.g. by passing the FileItem as a parameter of the slot.

* Code review changes (comment added)

Add a comment which describes that only the folder is opened without
selecting any file. Also explain why it is only done like this for now.

* Remove plugins/LadspaEffect/swh/ladspa-util.c (#5451)

This file contains no used code and it caused build problems, so we

* Fix crash on drawing line on the end of a graph (#5471)

This bug was introduced in dff76b2e83d4cfe140a8554f590cfd3780b61204.
The function changes [sample_end, sample_begin), but emits the signal
as if [sample_end, sample_begin] has been changed. That bug made
Multitap Echo crash when tweaking the cutoff of the 32nd stage.

This commit fixes the issue by emitting sampleChanged with sample_end - 1.

* Select the correct piano key for marking semitones (#5478)

When selecting a Piano Key to mark semitones in the Piano Roll we
select key from the y position of the pop-up menu and not the mouse.
Incidentally these two are most often the same as the menu builds
from the mouse y positon and down. If there is room for it. If there
is no room downward it will create the menu so the lower part of the
frame aligns with the mouse y position.
Fixed by creating a variable to hold the pressed key before creating
the menu.

* Fix #4201: BB editor: adjust cursor position (#5489)

This fixes an offset for cursors whose pointer position varies between
different themes.

* Fix #5194: Fix knobs moving too fast (#5360)

This PR fixes issues on systems where `QCursor::setPos()` has no effect
or is not reliable. These issues included knobs moving to fast on some
operating systems. Affected widgets are `Knob` and `LcdSpinBox`.

With this PR, on all operating systems, the `setPos` calls are removed and
the cursor is not hidden anymore, so the mouse keeps moving normally
when changing values of one of the widgets.

As now the previous pointer position keeps moving (instead of being reset
to the original position using `QCursor::setPos`), the mathematics that
translate pointer pixel distance to `Knob`/`LcdSpinBox` value increase
have to be changed:

* The `Knob` transition function is now linear and uses a new factor.
* `LcdSpinBox` now uses float values and saves the current float remainder
  (this is actually a separate issue revealed by this fix), leading to a fluent,
  non hanging movement.

* Compensate beat note length when stretching (#5515)

* Compensate beat note length when stretching

We allow stretching beat notes to normal notes but the length starts
from -192 so there is a lag for one whole note before any change is
seen. Compensate by setting the oldNote value to 1 when stretching
if the note is 0 or below in length.

* Allows instruments to keep the MIDI channel information when forwarding (#5470)

Now it's possible to forward received MIDI events with their original channel, either to another track or to the instrument plugin itself. To do that, the user must select the channel "--" on the MIDI output widget. In that case, all MIDI events will be forwarded with their original channel, and the MIDI events produced by the track itself will be sent with the default channel.

Adds a button on the BBEditor that clones the current BB track pattern, but without also cloning the song editor TCOs. That can be useful when an user is editing drumlines and wants to make a section with a slight variation for example.

* Changes the clone pattern method name

- Changes method name from cloneBBTrackPattern to clonePattern

On the FX mixer, the "Remove unused channels" action only checked for InstrumentTracks on every channel but ignored SampleTracks that could be linked to the particular FX channel. Because of that, if there was a channel where only SampleTracks are forwarded to and we clicked on "Remove unused channels", it was going to be removed. This commit fixes it.

* Better minimum length when resizing notes (#5512)

* Limit note length to quantization value

Draging a note to it's minimum value of 1 will add this new length to
the note if you later choose to stretch it which will not be clearly

a smaller value.

* Small refactor on FxMixerView.cpp and FxMixer.cpp

The code on FxMixerView.cpp and FxMixer.cpp were using the types TrackContainer::TrackList and QVector<Track *> unconsistently. TrackContainer::TrackList is just a typedef for QVector<Track *> so it makes sense that we use it, specially in terms of readability.

Places where QVector<Track *> were used are now replaced with TrackContainer::TrackList.

Also, we were not including "TrackContainer.h" directly (the typedef was likely being included indirectly through one of the other include files), so we also include this header on both source codes.

* Fixes small conflict on a new commit

On the PR #5470 (Allows intruments to keep the midi channel information when forwarding), merged on Jun 1st 2020 commit 97680e0, there's a line removed on the src/gui/widgets/InstrumentMidiIOView.cpp file ( m_outputChannelSpinBox->setEnabled( false ); ), because since the output channel is now relevant even when MIDI forwarding is disabled, we need that spinbox always enabled. It was also disconnected from the LedButton to keep it from disabling/enabling it.

On the PR #5171 (Removed the excessive margin in instruments' GUI (#5129)), merged on Jul 9th 2020 commit 9895472, the line was reintroduced, possibly because it was an older PR that wasn't rebased to the latest changes. This broke the output channel spinbox because now it was disabled on the constructor, but it was still disconnected from the LedButton, as a result always disabled.

This hotfix removes the line again to fix the issue.

* Fix bug from issue 5562 (#5565)

Fixes a small bug where projects that are saved with a soloed track can't restore the muted state of other tracks, because it doesn't store the m_mutedBeforeSolo variable on the project file.

With this fix, a new attribute is added to the Track DOM element, containing the muted state of tracks before the solo. When loading older projects that don't contain this attribute m_mutedBeforeSolo will be set to false.

* Fix crash on CLI rendering (#5579)

This is a temporary workaround. To make all export options available in CLI,
some properties of TimeLineWidget should be moved to a core class.

* Removes unused variable on SongEditor.cpp (#5600)

There was a variable declared but unused on the SongEditor.cpp file (method SongEditor::keyPressEvent), called QVector<TrackContentObjectView *> tcoViews. The variable was removed.

* Fix validPattern to check if hasAutomation as well (#5124)

* Changes the behavior of "solo" so it doesn't mute Automation Tracks (#5547)

* Changes the toggleSolo method

- Changes the toggleSolo method so it doesn't mute automation tracks (keeps their original state)

* Stop restoring Automation Track's mute values

- Since Automation Tracks are not affected by enabling solo on other tracks, there's no need (and it's even counter intuitive) to restore their previous mute value.
- Reduces a line by using "else if".

* Saves two lines merging 2 conditionals in 1

* Adds the new solo behavior as a new LED button

To allow the user choosing between the old solo behavior and the new one, a new LED button was added which will be used to enable the solo keeping the automation tracks states, while the red LED will enable the solo with the current behavior.

Changes to the code:
	- Added a purple LED image that will be used on the new button.
	- Increased the default width of the widget that holds the mute and solo buttons so the third one fits.
	- Changed the positioning of the LEDs on both the standard and compact track modes to accomodate them.
	- Added a new model called m_soloAutomationsModel, which is connected to the new LED button (m_soloAutomationsBtn). This will dictate the behavior of the toggleSolo method.
	- The red LED calls the toggleSolo method as before. The purple LED will change the m_soloAutomationsModel value and toggle the red LED, which will then call toggleSolo. But since the value of m_soloAutomationsModel will be different, the new behavior will be used on the method.

* Revert "Adds the new solo behavior as a new LED button"

This reverts commit fdbc8b2712d85cb7cafaf0298531557135cf9968.

After consulting fellow users and devs about this change to the PR, it was decided that adding a third button for the new solo behavior was not the best approach. This reverts the commit so we go back to just changing the solo behavior. Later an option can be added on LMMS settings to choose between the old and new behaviors.

* Adds an option to use the legacy solo behavior

This commit adds an option on LMMS settings (saved to the config file) to go back to the legacy behavior of the track solo button. The option can be found on Settings>General>"Use solo legacy behavior"

Changes to the code:
	- Since there's a change to the configuration file, an upgrade method was created (upgrade_1_3_0) to add the value to the config XML if it isn't already present (safety check).
	- An attribute is added to the DOM structure of the app configuration under the "app" tag, called "sololegacybehavior", which can be either 0 or 1.
	- Changes were made to include/SetupDialog.h, include/ConfigManager.h and src/core/ConfigManager.cpp to implement this new configuration option.
	- The toggleSolo method was changed to behave according to the value of the "sololegacybehavior" configuration.

* Changes the description of the solo setting

Changes the description of the solo setting on the Setup Dialog from "Use solo legacy behavior" to "Mute automation tracks during solo" since the latter is more descriptive and new users wouldn't be confused about what the legacy behavior was.

* Merges "if"s and "if-else"s where possible

A conditional could be merged by using the "||" logical operator and there was a "if" nested inside an "else" that could be merged into a single "if-else".

Very small code format change (keeping code block curly braces in separate lines).

* Uses default value instead of upgrading ConfigFile

Instead of using an upgrade method on the ConfigManager class to set a value to the sololegacybehavior parameter, we now use a default value on every call to ConfigManager::value that requests it.

* Removes repetitive method call

To make the loop more efficient, a local variable was created to hold the behavior of the solo selected in the setup dialog, instead of calling the ConfigManager::value method repeated times.


Since no code was added/removed from ConfigManager.cpp, it was restored to its original state. There's however a TAB character in a blank line on line 145, which was there at the beginning of this PR but removed during it. It was written again in this commit to remove ConfigManager.cpp from the "Files changed" list.

* Saves one line of code and adds a comment

* RemoteVstPlugin32: Fix Qt version check with MSVC 2019 + Qt 5.15 (#5607)

* Fix metronome playing when song is paused. (#5612)

* Implement Lv2 Urid feature (#5517)

This includes implementing general feature handling, since this is the first supported feature.

* Refactor PianoRoll (#5253)

* Rework PianoRoll paintEvent + some extras
* Split out PositionLine class to own file
* Refactor PianoRoll Q_PROPERTYs
* Reduce code by using Q_PROPERTY's MEMBER function and removing getter/setter functions
  After looking at the getters and setters, they did nothing different than what direct
  access would allow. Nothing outside of PianoRoll used the public functions as well.
  Considering these factors we can reduce the number of functions by 2x the number of
  Q_PROPERTIES, and go with direct access instead.
* Remove need for keyboard pixmaps
  With the recent change to allow zooming vertically, aligning pixmaps is a PITA. Since
  we have themes which can take brushes and colors, it would be simpler to take a solid
  color or a gradient with some extra style properties to resize the keys and text colors.
  While it will slightly be a downgrade from pixmaps since they can be anything really,
  this will allow us to customize the piano roll further moving forward.
* Added the ability to update margins for TimeLineWidget and StepRecorderWidget
  These take a X coordinate, which was hardcoded to WHITE_KEY_WIDTH, and never looked
  back. Now we can adjust on the fly if we need to. Currently this just allows us to
  shift the left margin to the style-defined white key width.
* Fix phantom pixmaps when PianoRoll not focused
* Update PositionLine class changes related to #5543

* Improve the context menu actions when multiple TCOs are selected (#5601)

* Starts implementing the feature

The idea of this branch is to allow actions triggered through the context menu of a TCO on the song editor to affect all the selected TCOs. With this commit, only the "Mute/unmute" action affects all selected TCOs, while the others retain their old behavior (only affect the TCO that owns the context menu).

For that, a method was created that processes all actions (the triggered action is parsed as a parameter to the method). In the case of the "Mute" action, it checks if the song editor has selected TCOs, and if it does it mutes/unmutes all of them.

* Allows selected TCOs to be removed too

Now the "Remove" action from the context menu will remove all selected TCOs if there are any.

* Starts implementing selected TCO cut and copy

Now, when multiple TCOs are selected, the context menu actions Cut and Copy will write a DataFile to the clipboard containing the TCO information, so it can later be used to paste it.

The Paste action now checks if there's data in the QApplication clipboard. If there is, it will later paste the TCOs (for now it just prints the data with qWarning). If there's not, it uses the regular TCO paste method that uses the internal LMMS clipboard. Because it now have to decide between the QApplication clipboard and the LMMS internal clipboard, the Clipboard::copy() method now clears anything in the QApplication clipboard, making it empty so LMMS can know it should use the internal clipboard instead in that situation.

Adds safety checks for the selected TCO views.

* Overloads TCW paste selection methods

This commit is a step towards implementing the paste feature of the TCO context menu. It overloads the TrackContentWidget::canPasteSelection and TrackContentWidget::pasteSelection methods so they can be called without having a QDropEvent (only the QMimeData with the copied TCOs information). The overloaded canPasteSelection(MidiTime, QMimeData, bool) method required a third argument which says whether pasting over the same bar should be allowed or not, because it shouldn't when the QDropEvent comes from the same application but should when it doesn't. That is defined in the canPasteSelection(MidiTime, QDropEvent) method.

Also, the pasteSelection(MidiTime, QDropEvent) isn't optimal, since it calls canPasteSelection twice (more details in the comments, but it's basically because the two canPasteSelection methods can return different values depending on the origin of QDropEvent). This could later be fixed by calling canPasteSelection before pasteSelection and removing it from inside the method altogether.

Next step is to add the "tco_" key to the mimeData on the Copy/Cut operations and implementing the paste operation using those methods.

* Adds the TCO type to the clipboard

Adds the key with the TCO type ("tco_" + type number + ":" + TCO Data XML) to the clipboard, so it can be later used by the canPasteSelection and pasteSelection methods.

* Apply changes to "src/tracks/SampleTrack.cpp"

Change the SampleTCOView::contextMenuEvent() method so it behaves the same way as the TrackContentObjectView::contextMenuEvent() method. For that, I had to change the ContextMenuAction enum and the contextMenuAction methods to be protected instead of private, so SampleTCOView can access it.

* Implement the paste action

Now that the canPasteSelection and pasteSelection methods were overloaded, it was possible to implement the paste action using the same logic as the Drag&Drop copy/paste.

Other small changes:
	- Removes the TCO views AFTER creating the TCO data file, instead of before (which probably resulted in an empty data file).
	- Uses the StringPairDrag::mimeType() instead of Clipboard::mimeType() since that's the one the methods from StringPairDrag.cpp recognizes.

* Removes QDebug header

Forgot to remove the QDebug header on the last commit.

* Creates a Context Menu on the TCW for "paste"

Now it's possible to paste a selection of copied TCOs anywhere in the TCW, as long as the rules to paste are met (same rules as Drag&Drop copy/paste). If the rules are not met the "Paste" menu action shows but is disabled.

* Small code refactoring

Saving a few lines of code.

* Avoids double call to canPasteSelection

This commit adds a third parameter to the pasteSelection overloaded method, which will define whether we whould skip the canPasteSelection check. The only situation where we will want to skip it is if we are calling pasteSelection from inside the other pasteSelection method, which will already have checked it. Because of that the default value is false.

Organizes comments as well.

* Separates methods for the actions on selections

Now the remove, copy, cut, paste and toggle mute actions have a separate method for applying them to selections, which are then called from the contextMenuAction method. That made the code more organized and the contextMenuAction method smaller.

Also, the mouse shortcuts for muting and removing (CTRL+middle button, middle button, CTRL+right button) now apply the action on selections as well.

* Fixes small bug and reorganize code

Fixes a small bug where using a mouse shortcut or choosing an action on a TCO that is not selected while other TCOs were selected would result in the selection being affected.

Also reorganizes the code so the conditional for choosing between the selection action and the individual action stays inside the method.

* Move logic to the action methods

Since the methods that called the action+Selection() methods didn't need the list of selectableObjects, I moved it to the inside of the action+Selection() methods and removed the parameter from them.

* Changes logic structure and labels

As suggested by Spekular, the logic structure was changed. Now, the mousePressEvent and contextMenuAction methods determine whether the action should happen to a selection of TCOs or an individual TCO. The list of TCOs to be affected populate a QVector list called "active", which is parsed to the action method that will apply the action to each object in the list.

I changed the method names to removeActive, cutActive, copyActive and toggleMuteActive, since I believe that better describe the behavior. The paste method is still called pasteSelection for now, because the paste behavior isn't related to the active TCOs but to the content of the clipboard.

The contextMenuEvent method on both src/core/Track.cpp and src/tracks/SampleTrack.cpp were changed so they also check if the right-clicked TCO is part of a selection or an individual TCO, and the labels for the actions are changed to better describe the behavior (i.e.: "Delete" for individual TCO and "Delete selection" for multiple TCOs).

* Make removeActive and toggleMuteActive static

removeActive and toggleMuteActive methods are now static so they can be called from anywhere in the code since they don't require a TCO view instance to work. That makes it possible for them to be used in the future if any feature requires this type of action to be called from out of a TCO view instance.

The same couldn't be done for the copyActive and cutActive methods because those require an instance of the TCO view to call them, since when copying to the clipboard some metadata is written using information from the object instance.

* Renamed TCO View paste method

I renamed the TCO View paste method from pasteSelection to just paste, since the TCO view doesn't currently have a paste method (only the TCO class). It's also a name that accurately describes the action: it will paste either a group of TCOVs or a single TCOV on the current TCOV.

I also moved the logic for deciding between the multiple TCOV paste and single TCOV paste inside the paste method.

* Moves repeated code to a new method

This commit adds another method to TrackContentObjectView called getClickedTCOs, which will return a QVector with the TCO views that are supposed to be affected by a context menu action (either the individual right-clicked TCO or the selection of TCOs). Code was updated on the other methods to make use of this new method.

Method names for actions that affect multiple TCOs were changed. Instead of calling them copyActive, cutActive, toggleMuteActive and removeActive, they are just called copy, cut, toggleMute and remove, hence they are overloaded methods for those actions that affect multiple TCOs (their differenciation is the arguments list, which is a QVector list for those).

* Avoid unnecessary calls to getClickedTCOs()

We use a ternary operator inside TrackContentObjectView::mousePressEvent to avoid unnecessary calls to getClickedTCOs when the list is not going to be used.

The contextMenuEvent method on both Track.cpp and SampleTrack.cpp was reformated to use a more appropriate indentation and spacing between method calls.
