* 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.
