* ThreadableJob: Move from AtomicInt to std::atomic
This is the first in a series of commits that migrates away from
AtomicInt towards the C++11 standard library types.
This would allow the removal of AtomicInt and related Qt
version-specific code.
While we're at it, also make ProcessingState an `enum class` so that
it's not implicitly convertible to integers.
* LocklessAllocator: Switch from AtomicInt to std::atomic_int
If it looks like some assignments around the Compare & Swap loops went
missing, it's because compare_exchange_weak() updates the first argument
to the current value when it fails (i.e., returns false).
* BufferManager: Remove extra AtomicInt include
* MixerWorkerThread: AtomicInt to std::atomic_int
* NotePlayHandle: AtomicInt to std::atomic_int
* Remove AtomicInt.h
* Move from QAtomicPointer to std::atomic<T*>
This removes some #ifdef trickery that was being used to get
load-acquire and store-release from Qt5 and "plain" (presumably
sequentially-consistent) loads and stores from Qt4.
C++11 (and subsequent C++ standards) provide portable ways to issue
atomic hardware instructions, which allow multiple threads to load,
store, and modify integers without taking a lock. The standard also
defines a memory model that lets you express the ordering guarantees
around these atomic operations. (x86 is relatively strongly-ordered, but
many other common architectures, such as ARM, are free to reorder loads
and stores unless told not to.)
This patch removes the lock from shared_object and replaces it with the
standard thread-safe reference counting implementation used in
C++'s std::shared_ptr, Rust's std::sync::Arc, and many others.

Previously lmms used themed dialogs for project saving/opening, but not
when editing settings (edit -> settings).
With this change, the settings editor also uses themed dialogs.
Adds the function randsv, which gives you persistent upon note plays and waveforms transit in the gui.
Moves lmms exprtk submodule back to latest upstream
Add `PerfTime` class representing a point in CPU time and `PerfLogTimer`, used for measuring and logging a time period. Used in `ProjectRenderer::run()
* Remove DataType.
An AutomatableModel should not need to know what concrete type it is.
Use virtual methods and implement them in the derived class instead of
testing the type in the base class.
* Remove unused method
* Remove m_hasLinkedModels
We can compute it on-the-fly with very little cost, and doing so
simplifies the code.
* Remove extra 'public:'
Probably a remnant of merging master
* Use owning types when possible.
Note: the QByteArray s is detached to mimic previous behavior;
detach() guarantees that the QByteArray uniquely owns its data, since
otherwise it's COW. This may be relevant in case Plugin:instantiate
modifies s.data() -- this way the original QString is safe.
* Make m_filter a unique_ptr.
* Make m_activeRenderer a unique_ptr
* use std::string instead of strcpy + buffers
We copy the QString, so it makes sense to accept it by value and _move_
it into the collection instead. This causes the caller to move any
rvalue QString into the function, and then the QString is never actually
copied at all.
