This function is useful if a floating point comparison requires a
certain precision. The return value can be considered as the precision.
For instance, if you want to compare two 32-bit floating point values
and all you need is a 24-bit precision, you can use this function like
this:
if (qFloatDistance(a,b) < (1 << 7)) { // The last 7 bits are not
// significant
// precise enough
}

The code uses a QSignalSpy to check whether the thread started,
but the signal emission (and subsequent appending to the spy) and
the check for spy.count() before the final thr.wait() are not
synchronized:
The signal emission happens-after the thr.start() and -before the
final thr.wait(). Likewise, the spy.count() happens-after thr.start()
and -before thr.wait(), but neither one happens-before the other.
Thus, there is a data race.
The wait(200) between thr.start() and mutex.unlock() doesn't help,
either, because we check only that it doesn't return true, iow, we
check that it timed out. But it will happily do that if the thread
has not yet started executing, so there's no happens-before relation
to be had via that avenue, either.
I first fixed by moving the spy.count() check to after thr.wait().
In that case:
signal emission happens-before thread finishing
happens-before thr.wait() returning
happens-before spy.count()
so no race.
Arguably, that makes the check rather useless, so I decided to remove
it completely.

When Daylight Time transtion goes from Standard Time to Daylight Time
there is a "missing" hour, i.e. at 2am CET the clock goes forward to
3am. Currently QDateTime ignores this gap and considers the time to be
valid and able to be manipulated. This change respects the transition,
so any time set in the missing hour is considered invalid, and any date
maths returns valid results.
The validity in the current time zone needs to be checked every time
isValid() is called in case the system time zone has changed since the
last time it was checked. This is done by calling mktime to check the
returned result matches the expected result. This could be very
inefficient, but the returned offset value is cached each time so
mktime is not required to be called again within each method call,
effectively meaning mktime is called the same number of times by
each method. Note that this means any new methods added must be
careful to ensure either isValid() or refreshLocalTime() is called
first by any method needing to use the UTC value.
[ChangeLog][QtCore][QDateTime] The Standard Time to Daylight Time
transition for Qt::LocalTime is now handled correctly. Any date set
in the "missing" hour is now considered invalid. All date math results
that fall into the missing hour will be automatically adjusted to a
valid time in the following hour.

Change from storing the date and time as QDate and QTime to a serialised
msecs format. This format is a direct translation of the QDate and
QTime values, it is not the actual msecs since the Unix epoch. This
msecs format ensures we are always able to recreate the original QDate
and QTime values, but should still simplify the code and improve
performance.
Because we no longer store the explicit date and time we need to store
their isNull()/isValid() status separately.
The changes in storage results in the same memory footprint as before.
Note that this change does not optimize the code nor set out to fix the
known bugs, it only seeks to maintain the current behavior, although
some bugs are fixed implicitly. More bug fixes and optimizations will
follow.

Up to now, it was only possible to connect to functors in a direct
way, without being capable of using Qt::ConnectionType. This patch
allows for specifying a receiver for Functors and function
pointers, hence making it possible to specify effectively the
connection type.
To do this properly, it was needed to add an enum in FunctionPointer
representing whether the considered function is a member function
or not, to reduce ambiguity upon overloaded calls.
Moreover, now senders are checked for the existence of a slot obj
as well. This way, should the context be freed, the slot obj and
the functor contained in it will be freed as well.
On a side note, connecting to a static slot
(like QCoreApplication::quit) specifying the receiver object is
now compiling.

The responsibility of sendWindowSystemEvents() is to process events from
the window system. Historially that logic was part of the QPA/QWS event
dispatcher, which naturally also sent posted events. Through refactoring,
the code at some point ended up in in the QWindowSystemInterface class,
still with the posting of events in place.
This resulted in QPA event dispatchers adopting a pattern of just calling
sendWindowSystemEvents(), as that would cover both posted and window system
events. Other event dispatchers would call sendWindowSystemEvents(), and
then use a base-class implementation from QtCore for processing events,
resulting in two calls to QCoreApplication::sendPostedEvents() per
iteration of processEvents(). This breaks the contract that processEvents
will only process posted events that has been queued up until then.
We fix this entanglement by removing the sendPostedEvents() call from
QWindowSystemInterface::sendWindowSystemEvents() and move it to the
respective event dispatchers. For some EDs it means an explicit call
to sendPostedEvents, while others were already doing sendPostedEvents
though a separate source (GLib), or using a base-class (UNIX/BB), and
did not need an extra call.
We still keep the ordering of the original sendWindowSystemEvents()
function of first sending posted events, and then processing any
window system events.
