Add the event loop quitlock feature to QtCore.
A feature of a ref-counted quit (managed by a quit-lock class)
is added to both QEventLoop and QCoreApplication.
This allows, for example, an event loop to quit() when there is
no more work for it to do.
quitOnLastWindowClosed is implemented in terms of the refcount in
QCoreApplication so that jobs can be completed before the
application quits.
