Summary:
* `NULL` -> `nullptr`
* `gui` -> Function `getGUI()`
* `pluginFactory` -> Function `getPluginFactory()`
* `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.
* Fix for Icons and comboboxes mismatch in arpeggiator in Instrument Editor #5494
(https://github.com/LMMS/lmms/issues/5494)
Introduce a static const int variable for the default height of a ComboBox.
Set this height already in the constructor of the ComboBox object.
Update all modules setting the height of a ComboBox object to make use of the new constant.
* Replace 'const int' by 'constexpr int' after review.
* advanced config: expose hidden constants to user screen
* advanced config: add support for FFT window overlapping
* waterfall: display at native resolution on high-DPI screens
* waterfall: add cursor and improve label density
* FFT: fix normalization so that 0 dBFS matches full-scale sinewave
* FFT: decouple data acquisition from processing and display
* FFT: separate lock for reallocation (to avoid some needless waiting)
* moved ranges and other constants to a separate file
* debug: better performance measurements
* minor fixes
* build the ringbuffer library as part of LMMS core
* Remove bin2res, use Qt's resource system
* Use QDir search paths and QImageReader in getIconPixmap
* Don't include "embed.cpp" in plugins
* getIconPixmap: Use QPixmapCache, use QPixmap::fromImageReader
* Require CMake 2.8.9
* Fix ReverbSC embed usage

LMMS now properly builds and runs with Qt5. Various deprecated functions
had to be replaced like QString::toAscii()/fromAscii(). Also occurences
of FALSE/TRUE have been replaced with false/true.
LmmsStyle now derives from QProxyStyle and sets a style instance as base
style (Plastique for Qt4, Fusion for Qt5).
MOC files are not included anymore but added as regular source files.
What's missing is support for embedding VST plugins into a subwindow
inside LMMS on Linux/X11 due to missing QX11EmbedContainer class in Qt5.
Build instructions can be found in INSTALL.Qt5
Minimum version requirement for Qt4 has been raised to 4.6.0 for best
API compatibility between Qt4 and Qt5.
