Historically, the PeakController has had issues like attack/decay knobs
acting like on/off switches, and audio artifacts like buzzing or
clicking. This patch aims to address those issues.
The PeakController previously used lerp (linear interpolation) when
looping through the sample buffer, which was in updateValueBuffer. This
lerp utilized attack/decay values from control knobs. This is not the
correct place to utilize attack/decay because the only temporal data
available to the function is the frame and sample size. Therefore the
coefficient should simply be the sample rate instead.
Between each sample, processImpl would set m_lastSample to the RMS
without any sort of lerp. This resulted in m_lastSample producing
stair-like patterns over time, rather than a smooth line.
For context, m_lastSample is used to set the value of whatever is
connected to the PeakController. The basic lerp formula is:
m_lastSample = m_lastSample + ((1 - attack) * (RMS - m_lastSample))
This is useful because an attack of 0 sets m_lastSample to RMS, whereas
an attack of 1 would set m_lastSample to m_lastSample. This means our
attack/decay knobs can be used on a range from "snap to the next value
immediately" to "never stray from the last value".
* Remove attack/decay from PeakController frame lerp.
* Set frame lerp coefficient to 100.0 / sample_rate to fix buzzing.
* Add lerp between samples for PeakController to fix stairstep bug.
* The newly added lerp utilizes (1 - attack or decay) as the
coefficient, which means the knobs actually do something now.

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 .

* Update ringbuffer submodule to fix includes
* Remove cyclic includes
* Remove Qt include prefixes
* Include C++ versions of C headers
E.g.: assert.h -> cassert
* Move CLIP_BORDER_WIDTH into ClipView
This allows to remove includes to TrackView.h in ClipView cpp files.
* Elliminate useless includes
This improves the include structure by elliminating includes that are
not used. Most of this was done by using `include-what-you-use` with
`CMAKE_C_INCLUDE_WHAT_YOU_USE` and `CMAKE_CXX_INCLUDE_WHAT_YOU_USE`
set to (broken down here):
```
include-what-you-use;
-Xiwyu;--mapping_file=/usr/share/include-what-you-use/qt5_11.imp;
-Xiwyu;--keep=*/xmmintrin.h;
-Xiwyu;--keep=*/lmmsconfig.h;
-Xiwyu;--keep=*/weak_libjack.h;
-Xiwyu;--keep=*/sys/*;

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.

* `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.
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.
Also featuring a very efficient buffer-based system for transporting sample-exact control data
Also interpolation for automations
The native Amplifier is a reference implementation for taking advantage of sample-exact data and is currently
the only one that does so, it can be used to test things out, and as documentation/example for implementing the
same elsewhere
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.
