Compared to std::shared_ptr, QSharedPointer requires 2x the atomic operations per copy, and this code uses _a lot_ of copies. Port to std::shared_ptr. The uses are all in inline, non-exported code, so there's no BC or SC issue here. Old code will happily continue to use its QSharedPointer-based code, while recompiled code will enjoy the transparent efficiency gain. This also helps prepare QtCore for an eventual QT_NO_SHARED_POINTER (which QtCore will not be able to set on itself, because QPointer is still not ported away from QWeakPointer, but which should affect as few headers as possible).
