Qt 5.6 ABI incompatibility due to qt_handleMouseEvent

Qt 5.6 removed the following overload from qtestmouse.h:

qt_handleMouseEvent ( QWindow* w, QPointF const& local, QPointF const& global, Qt::MouseButtons b, Qt::KeyboardModifiers mods )

See http://abi-laboratory.pro/tracker/compat_report/qt/5.5.1/5.6.0/8f965/abi_compat_report.html#Removed

This broke PyQt binary compatibility on Archlinux, as it's probably inlined from QTest::mouseEvent: https://bugs.archlinux.org/task/48734

It'd be nice if it could be brought back in 5.6.1.
