The code is restructured to only loop over the non-empty connection
lists. This can be checked early while the mutex is locked already,
thus removing mutex lock/unlock calls that were done previously just
to realize the allsignals list is empty and can be skipped.
Additionally, at the very end of the loop over the last signal
connection list, the mutex was acquired even though it doesn't need
to be as we will quit the loop anyways.
This patch leverages these facts to remove the mutex locks which alone
has a considerable impact on the corresponding signal/slot benchmark.
The instruction count goes down by ca. 13%, while cycle count and
runtime drop by about 29%.

This issue is reproducible on OS X when using a Magic Mouse
or a combination of Magic Trackpad and regular mouse. In these
cases it's possible to start a scrolling gesture on one widget
and move the mouse cursor over another widget.
Although we send the wheel event phase information, we never
made any use of it. This means that a widget would start
scrolling even though it never received a ScrollBegin event.
In this patch, we make sure the scrolling cycle is respected
and that once a widget starts scrolling, it'll be recieving
all the wheel events until a ScrollEnd event reaches the
application.
For those input devices not supporting a proper phase cycle,
we introduce a new (undocumented) phase value, NoScrollPhase.
If the wheel event phase is NoScrollPhase, then we ignore
the current scroll widget and proceed as usual. This value
is the default for wheel events. It's up to the platform
plugin to set the proper phase value according to the data
received from the OS.
Finally, we fix a few of QWheelEvent constructors to properly
initialize the phase and source properties.

Virtually all code in Qt that inspects a QRegion does
so by calling rects(), which returns a QVector<QRect>.
But rects() has a problem: A QRegion that contains just
one rectangle internally is not represented by a QVector,
and the mere act of calling rects() makes QRegion create
one.
So, expose the fact that QRegion is a container of QRects
to users by providing iterators and begin()/end(), which
can be nothrow, since for the one-rectangle case, instead
of vectorize()ing the region, we just return pointers to
(and one past) the 'extent' rectangle.
As a consequence, the iterator type is just const QRect*,
but I think that whatever containers QRegion may use under
the hood in the future, it will be certainly one that is
layout-compatible with a C array.
No mutable iterators are provided, since QRegion maintains
a running bounding-rect, so a mutable iterator would have
to call into QRegion for every change, which doesn't make
sense.
[ChangeLog][QtGui][QRegion] Is now iterable as a container

Q_FOREACH over a QVarLengthArray or std containers
is a particularly bad idea (because of the deep
copy that Q_FOREACH then performs).
Use C++11 range-for (without qAsConst(), because
neither QVLA nor std containers are CoW).
Saves 5.7KiB in text size on optimized GCC 5.3
Linux AMD64 builds.

`ar' tool from latest binutils shows warning:
ar error: `u' modifier ignored since `D' is the default (see `U')
Warning message includes word "error" so QtCreator processes it as
error in UI.
`ar' command-line option `u' might be dropped safely because it is
unnecessary. Option `c' is added to suppress extra `ar' warnings.
Other build systems are also affected. For example, automake:

Given the flakyness of cursor positioning, loosen the check to only verify
that the cursor is outside the window. The hint is only active on Windows
depending on a system setting.

The algorithm used was:
- If possible, just declare the container const
- Otherwise, for first()/last(), use constFirst()/constLast()
and for front()/back(), to not destroy the use of the STL
API subset, use qAsConst()
Did some caching of function returns here and there, and
converted one 0 to nullptr as a drive-by.
Also saves almost 4KiB in text size on optimized GCC 4.9
Linux AMD64 builds.
