Since Qt's connections are thread-safe, QStateMachine's plumbing

By default, QStateMachine lazily registers signal transitions (i.e.,
connects to the signal) when the transition's source state is
entered. The connections are established in Qt::AutoConnection mode,
which means that if the sender object lives in a different thread,
the signal processing will be queued.
But if a sender object's signal is used in an out-going transition
of the target state of the queued transition, it's possible that a
second signal emission on the sender object's thread will be
"missed" by the state machine; before the machine gets around to
processing the first queued emission (and registering the
transitions of the new state), a sender object on the other thread
could have emitted a new signal.
The solution employed here is to eagerly register any signal
transition whose sender object is on a different thread; that is,
register it regardless of whether the transition's source state is
active.
Conversely, when a machine's transitions are unregistered (i.e.,
because the machine finished), signal transitions with sender
objects on other threads should be left as-is, in case the machine
will be run again.
This doesn't solve the case where the sender object is moved to a
different thread _after_ the transition has been initialized.
Theoretically, we could catch that by installing an event filter
on every sender object and handle the ThreadChange events, but
that would be very expensive, and likely useless in most cases.
So let's just say that that case isn't supported for now.

The SCXML spec had a bug that would cause the initial state of a
compound state within a parallel state group to be entered even if
the transition specified another (non-initial) state of the compound
state as its target. This only happened if the transition had
multiple target states.
The bug has been fixed in recent revisions of the SCXML spec. This
commit implements the fix, which is to walk the ancestors of the
transition's target states only after all the target states
themselves have been added, so that the default initial states are
correctly overridden/ignored.

In the old implementation, property assignments
(QState::assignProperty()) were "second-class citizens".
Assignments were not really integrated into the state machine
algorithm, but rather done as a separate step
(QStateMachinePrivate::applyProperties()). While that was
convenient for SCXML spec transcription purposes, it resulted
in some pretty poor semantics on the user side:
* Properties were not assigned until _after_ both the
QAbstractState::onEntry() function had been called and the
QState::entered() signal had been emitted.
* Automatic property restoration (QStateMachine::RestoreProperties)
did not play nice with nested states (and parallel states, in
particular).
The proper fix is to refactor the implementation to make
property assignments first-class in the core state machine
algorithm (QStateMachinePrivate::microstep()).
In practice, this meant splitting some steps. Instead of calling
exitStates() straight away, we now first only compute the states
to exit (without actually exiting them), and use the resulting set
to compute which properties are candidates for restoration.
Similarly, instead of calling enterStates(), we first only compute
the states to enter (without actually entering them), and use the
resulting set to compute which properties are assigned by the
entered states.
With that in place, the rest was a matter of moving the various
chunks of the old applyProperties() logic to the place where they
belong in the per-state entry/exit.
All existing autotests pass. Added several tests that verify the
desired semantics in more detail.

Valgrinding the new benchmark indicates that the percentage of the

on ia32, for that particular stress test; the increase is the
combined cost of calling metaObject(), QMetaObjectPrivate::signal(),
