5fd9fe02ff QStateMachine: add defaultTransition in QHistoryState
The history state had the limitation that it was hard (or impossible) to
use when more than one default state had to be entered. For example,
using it in a parallel state was impossible without ending up in an
infinite loop.

This patch changes the QHistoryState to only have an initial transition,
and the state selection algorithm is changed accordingly. It also brings
QStateMachine closer to the SCXML standard.

The existing defaultState is implemented on top of the
defaultTransition: when used, a new transition, with the default state as
its target, is set as the defaultTransition.

0cd34a0c39 StateMachine: remove initial state for parallel states.
A parallel state cannot have an initial state, as all children of the
parallel state will be entered. Setting such an initial state on a
QState marked as ParallelStates would already produce a warning and
ignore the initial state. Now any initial state that has been set before
changing the child-mode to ParallelStates will also produce a warning
and remove the previously set initial state.

The behavior of "external" and "internal" transitions is identical,
except in the case of a transition whose source state is a compound

an internal transition will not exit and re-enter its source state,
while an external one will.

bd15b23987 QStateMachine: cache expensive calculations.
As nothing changes in the state machine when selecting transitions for
events and then calculating the exit- and entry-sets, some calculations
can be cached.

The exit set for a transition was calculated multiple times. First in
removeConflictingTransitions, where the two loops would each calculate
them multiple times. Then secondly in microstep(), which would calculate
the exit set for all transitions.

Transition selection, exit set calculation, and entry set calculation
all calculate the transition domain and effective target states for
transitions.

b2f6406b6f QStateMachine: remove conflicting transitions after selection.
After selecting all (enabled) transitions for a microstep, filter out
any conflicting transition. The actual conflict resulution is done by
ordering the transitions in order of the states that selected them.

For example: if an event would trigger two transitions in a parallel
state where one would exit that state and the other would not, this
filtering prevents the state machine from selecting both states (as this
case is an invalid state of the whole machine).

This also fixes the exit set calculation for parallel states when one of
its substates is exited and subsequently re-entered in the same
transition. Previously, the parallel state was not exited, and
subsequent re-entry was ignored (because it was still active). Now it is
correctly exited and re-entered.

A side-effect of the transition ordering mentioned above is it also
fixes the non-deterministic behavior of which of the conflicting
transitions is taken.

[ChangeLog][QtCore] Fixed an issue where the state machine could end up
in an invalid state when transitions from a parallel state were not
checked for conflicts.
[ChangeLog][QtCore] Fixed a case where a parallel state was not exited
and re-entered when one of its substates was exited and subsequently

e616bd2641 QStateMachine: fix history state restoration.
When a history state is entered that has an actual saved history (so not
the initial state), the entry set was calculated wrongly in some cases.
See the bug report for the specific case.

The fix is to fully implement the standard, so method names in the
private class are updated to reflect the names as used in the standard.

Note that, as mentioned in the bug report, the algorithm as described in
http://www.w3.org/TR/2014/WD-scxml-20140529/ has a bug. What is
implemented is the fixed algorithm as described in the current working
draft as of Friday March 13, 2015. This draft can be found at:
http://www.w3.org/Voice/2013/scxml-irp/SCXML.htm

[ChangeLog][QtCore] Fixed an issue where a history state restore would
activate too many states, possibly putting the state machine in an
invalid state.

8efcfda41f statemachine: Really fix signal transition handling in multi-threaded setup
Commit f9a17d7f0f fixed it for the case
where the sender object is in a different thread at transition setup
time. However, it still didn't work if either the sender object or the
state machine was moved to a different thread at some later time,
before the machine was started.

Therefore: Bite the sour grape and traverse all the machine's
transitions when the machine is being started, registering those
signal transitions whose sender objects are in other threads.

This will increase the machine's startup time (proportional to the
number of transitions), but at least it works in all known scenarios,
meaning we don't have to document weird restrictions regarding the
order in which the user's operations have to be done.

672b5b7ab6 Set the Qt API level to compatibility mode in all tests.
Qt 5.0 beta requires changing the default to the 5.0 API, disabling
the deprecated code. However, tests should test (and often do) the
compatibility API too, so turn it back on.

3a2bc9530e statemachine: Make states exit order spec-compliant
The SCXML spec states that entry order should be equivalent to
"document order" and exit order should be "reverse document order".
Since QStateMachine uses child order for the entry order, the exit
order should be reverse child order.

cd1351401f statemachine: Move RestorePolicy enum to QState class
This makes it possible to add API for setting the restore policy
per state, or even per property assignment (QTBUG-17861).

This change is fully source compatible with Qt4.

0b66f723f0 Add QStateMachine constructor that takes a ChildMode
Back when QStateMachine was changed to inherit QState, this
constructor was conveniently left out because setting the state
machine (root state) to be a parallel state group didn't actually
work. But as of commit d281aa6936,
it does work, so add the missing constructor.

95b6826ed4 statemachine: Make signal transition registration thread-safe
Since Qt's connections are thread-safe, QStateMachine's plumbing
around them should be thread-safe too.

f9a17d7f0f statemachine: Fix signal transition handling in multi-threaded setup
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.

22c7a1fd9b statemachine: Fix dynamic transition registration edge cases
Some of the transition constructors didn't call the maybeRegister()
function, causing the transitions to be ignored if they were created
when the state machine was running and the transition's source state
was active.

Added tests that cover all possible cases.

0d56dac3bc statemachine: Set correct signal index when signal is non-normalized
The originalSignalIndex member was not set if the signature had to be
normalized. This caused the SignalEvent passed to onTransition() to
report a signal index of -1.

Improve the signal transition tests so they check both the event
passed to eventTest() and onTransition().
