Until now, Mixer not only was responsible for rendering audio buffers
but also managed writing them to audio backend (through a FIFO) and
handled various quality related parameters.
All this functionality has been moved into the new AudioOutputContext
class. It glues together AudioBackend (formerly called AudioDevice),
global quality settings and the Mixer.
The AudioOutputContext class creates a FifoWriter which calls
Mixer::renderNextBuffer() and writes the output into the BufferFifo of
the AudioOutputContext it belongs to. The BufferFifo is read by the
according AudioBackend which belongs to the AudioOutputContext as well.
The AudioOutputContext also handles resampling in case the AudioBackend
wants the buffers in a different samplerate.
During this rewrite the Mixer class and the according source files have
been renamed from "mixer" to "Mixer". This results in small changes
all over LMMS' code base.
While regular instruments were excluded from processing when muted
this did not happen for InstrumentPlayHandle-based instruments. Muting
for exampling tracks with VSTi's inside did not decrease CPU usage.
Checking whether related InstrumentTrack is muted before calling
Instrument::play() fixes this issue.
Closes#2857426.
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
* cleaned up code and improved coding style
* removed old SINGLE_SOURCE_COMPILE macro relicts
* use QString::toUtf8() instead of QString::toAscii() wherever possible
Added generic drag'n'drop support for all instrument views. All
resources supported by the according instrument now can be dropped
onto instrument view without any extra code in actual instrument.
Additionally renamed some files and classes related to InstrumentView
class to match new style.

* fixed names of various member methods of notePlayHandle class
* full MIDI velocity when pressing key on test piano
* send volume changes of a notePlayHandle as MidiKeyPressure events
* send pitch changes of instrument track as MidiPitchBend events
* added detection for running MIDI notes
* correct calculation of MIDI key - makes remotePlugins respect base note settings

* made modelView take a QWidget-pointer argument
* trackContentObject-ctor now calls track::addTCO() directly
* optimize various loops to use iterators/const_iterators instead of a running index variable
* drag'n'drop doesn't fool around with pointers anymore - instead use unique journalling-IDs
* moved drag'n'drop handling code from knob to automatableModelView so that all controls can benefit from that

* lmmsStyle-class: load stylesheet here
* comboBox/comboBoxModel: use pixmapLoader-pointers rather than QPixmap-pointers
* in plugin-descriptor, hold a pointer to pixmapLoader instead of QPixmap itself
* embed-framework: introduced pixmapLoader and pluginPixmapLoader-classes for abstracting QPixmap-instantiation - models can hold pixmapLoaders without actually instantiating a QPixmap-object and views can access the pixmap
* main-window: removed settings-menu and moved setup-dialog to edit-menu
* config-manager: removed all the obsolete first-startup-wizard-code
