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.

Make it possible to enable and disable both at the
environment variable level and at the source code
level. This applies to scaling done by Qt using display
density information provided by the operating system.
Disabling is done with a 'veto' system: both the environment
and source code my prevent the other for enabling
scaling. This covers use cases of 'my system does not
provide correct display metrics' and 'my application
needs access to display pixels', respectively.
On the environment, scaling is now enabled with
QT_AUTO_SCREEN_SCALE_FACTOR=1 and disabled with
QT_AUTO_SCREEN_SCALE_FACTOR=0. In source code the
corresponding application attributes are AA_EnableHighDpiScaling
and AA_DisapleHighDpiScaling. Not setting any of these
indicates 'no preference'.
The global scale factor set by QT_SCALE_FACTOR is
not affected by any if the disablers.

Most processors have carry flags which they set on addition overflow, so
it's a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version.
Tested to compile on:
Architecture Compiler
x86 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
x86-64 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta

PowerPC 64 GCC 4.9, Clang 3.6*
SPARC Clang 3.6*
SPARCv9 Clang 3.6*
[*] supports the intrinsics
If the compiler does not offer a way to detect an overflow, we do it by
hand. For unsigned additions, that's easy, since the C++ language
specifies the behavior of the overflow. That's also the reason why this
code is implemented only for unsigned integers.
For the multiplication, if the compiler does not support widening
multiplications, we do it with a division instead. This is necessary for
GCC < 4.5 and compilers not compatible with GCC or MSVC.

Justification: intuition indicates that Q_OS_MAC refers to OS X. Reality
indicates it refers to OS X, iOS, watchOS, and tvOS. Technical
correctness requires that it match reality. Backwards compatibility
dictates it can't be changed anyways. Conclusion: an extremely confusing
macro that no one knows how to use properly.
When Q_OS_MACX was repurposed for OS X (and later, Q_OS_OSX introduced),
Q_OS_MAC was kept around to allow differentation between Q_OS_DARWIN
(the grandfather OS of everything - OS X, iOS, watchOS, tvOS, and
theoretically "open source Darwin derivative"). However, given that
every attempt at a non-Apple Darwin based operating system has failed
and sees virtually no interest at scale, this distinction is not useful
in Qt for the confusion it causes in return, especially considering that
there are several cases in Qt where Q_OS_MAC should be Q_OS_DARWIN or
vice versa, and sometimes the correct macro is not even entirely clear.
Therefore, Q_OS_MAC can be deprecated. In the extremely unlikely case
that differentiation between Darwin core, and commercial Darwin-based
operating systems from Apple is required, I suggest introducing
Q_OS_APPLE (a superset of Q_OS_DARWIN, and subset of Q_OS_OSX, Q_OS_IOS,
Q_OS_WATCHOS, and Q_OS_TVOS). Until it is needed, Darwin, OS X, iOS,
watchOS, and tvOS defines should be perfectly sufficient for every
real-world use case.

This symbol will exist with different ELF versions, allowing us to know
which version of Qt a given library or application was linked
against. When this symbol gets used, automatic packaging tools will
extract the dependency. The trick here is that the application uses
qt_version_tag without knowing which version is current, but the linker
resolves it to the current version and records that.
For example, if this were used with Qt 5.5, RPM's find-requires on an
application using QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Whereas find-provides on QtCore would print:
libQt5Core.so.5()(64bit)
libQt5Core.so.5(libQt5Core.so.5)(64bit)
libQt5Core.so.5(Qt_5.0)(64bit)
libQt5Core.so.5(Qt_5.1)(64bit)
libQt5Core.so.5(Qt_5.2)(64bit)

libQt5Core.so.5(Qt_5.4)(64bit)
libQt5Core.so.5(Qt_5.5)(64bit)
libQt5Core.so.5(Qt_5)(64bit)
Therefore, automatic dependency resolution would have the information it
needs to conclude that the application requires Qt >= 5.5.

Add a coordinate scaling layer to QtGui, which supports 'devicePixelRatio'
type high-dpi on all platforms, in production and also for
development and testing purposes.
High-DPI scaling is opt-in, by setting environment variables:
QT_SCALE_FACTOR - sets a global scale factor
QT_AUTO_SCREEN_SCALE_FACTOR - sets per-screen scale factors,
where the scale factors are provided by the platform plugin.
This QtGui scaling can be used instead of or in addition to scaling
done by the window system. This distinction is not visible to
applications [when they use Qt API], which will see a change in
the value returned by the devicePixelRatio() accessors as usual.
Introduce a new (private to Qt) coordinate system: native pixels.
The coordinate system stack now looks like:
device-independent pixels (app, upper parts of Qt)
native pixels (lower parts of Qt Gui, platform plugins)
device pixels (backing stores and OpenGL)
Add private QHighDpi namespace with scaling functions that convert
between device-independent pixels and native pixels:
T toNativePixels(T, QWindow *);
T fromNativePixels(T, QWindow *);
Add scaling calls the QWindow (and friends) cross-platform implementation,
around the calls to QPlatformWindow functions. QPlatformWindow now uses
native coordinates - platform code remains largely unchanged since native
coordinates are window system coordinates.
QWindow now uses (possibly) scaled coordinates. This means that
platform plugins no longer can rely on QWindow::geometry() and
related functions. QPlatformWindow::windowGeometry() and other
convenience functions have been added for use when the platform
plugin needs to convert scaled geometry to native geometry.
Add Qt::AA_NoHighDpiScaling, which can be use to disable any
scaling in QtGui, effectively ignoring the environment variables.
(Note that this does not disable any scaling done by the window
system.)

Expand Linux distribution detection to /etc/redhat-release and
/etc/debian_version to follow what /usr/bin/lsb_release script does.
If /usr/bin/lsb_release fails to extract the distribution information
from /etc/lsb-release, it then checks /etc/redhat-release and, as a last
fallback, /etc/debian_version.
Some Red Hat distributions have a /etc/lsb-release file that
does not provide the values we are looking for (DISTRIB_ID,
DISTRIB_RELEASE and DISTRIB_DESCRIPTION).
If both productType or productVersion are empty after reading
/etc/lsb-release, readEtcLsbRelease() will return false, allowing
further parsing of /etc/redhat-release. This scenario mimics what
the /usr/bin/lsb_release script does if /etc/lsb-release does not
contains enough information.
The productType and productVersion returned by QSysInfo after reading
/etc/redhat-release match the distributor id and release information
returned by the /usr/bin/lsb_release script.
For Debian Linux distributions where /etc/os-release, /etc/lsb-release
and /etc/redhat-release are not available nor usable, the
/usr/bin/lsb_release script also checks for the /etc/debian_version
file.
In this case, we also enable parsing of /etc/debian_version to retrieve a
fallback productVersion, the productType being set to Debian.

Normally when maximizing a window it will cover the available geometry
of the screen, as represented by QScreen::availableGeometry(), which
typically excludes status/menu bars and application launchers.
On some platforms it may still be possible to place windows in the areas
of the screen that are outside of the available geometry, but this will
result in the window being partially covered by (possibly) transparent
system UIs. The new flag allows the user to specify that when maximizing
the window it should try to cover as much as possible of the screen
geometry (in contrast to going full screen, which would typically
hide any system UIs).
For iOS this is a common use-case, as the status bar is transparent,
and the user-interface guidelines for iOS7 and up recommend taking
advantage of the full screen space, while keeping any user-interaction
elements still inside the available geometry of the screen.

The code is going to skip a few frames from QtCore. Since we cannot know
how many, we take a few more than necessary.
This patch changes the additional number of frames from 15 to 7

We call backtrace_symbols several times for only one frame at the time.
So we are not looking up addresses we don't need after we printed the
right number of frames.
Calling many times backtrace_symbols means we do more malloc, but that's
negligible compared to the time we save. We anyway do a lot of other
allocations because of the regexp operations and such
So this patch is then saving about 10 frames lookups which allow to print

Short version: fix build on QNX 6.5.0.
C++11 has been included on QNX 6.6.0's libcpp (Dinkum C++11 libs), while
continuing to be unsupported by the older QNX 6.5.0 toolchain.
This patch updates the mechanism for detecting the QNX's libcpp that is being
used during compile time, and also updates the list of C++11 features to be
disabled when QNX C++11 support is not present by adding
Q_COMPILER_UNICODE_STRINGS and Q_COMPILER_NOEXCEPT to it.

The way swapping is supposed to work is:
1. Each type supplies a swap() function or function template in its
namespace. Any good STL implementation will find it there through
ADL. As will the primary qSwap() template.
2. Each use of swap() in Qt, in particular in template code, should
use qSwap() instead of std::swap() or the using+swap-trick, because
qSwap() automatically enables ADL. It also has a sophisticated
conditional noexcept specification that can be used in the
custom swap() functions' own noexcept clause.
This change also allows us to convert implicitly-shared classes'
member-swap functions to noexcept one at a time, because the
specialization will no longer be in conflict with the primary
template regarding exception specifications. The primary's
specification could, of course, be reused here, but it's complex
and if the machinery around it is changed later on, it will not
affect Q_DECLARE_SHARED classes.

The sequence of (__GNUC__ * 100 + __GNUC_MINOR__) was used in quite a
few places. Simplify it to make the code more readable.
This follows the change done for Clang, which was quite necessary since
Apple's version of Clang has different build numbers.

With the side-effect that variables and functions in the argument are
now "used". This means we don't need to #ifndef functions only used in
assertions: the compiler will eliminate them by dead code elimination.
Due to the mandatory short-circuiting of the condition, no functions
will ever be called and this expands to no more code than before.
On the negative side, because we won't get warnings for unused variables
initialized outside the Q_ASSERT, non-inlineable calls will not be
elminated by dead code elimination, so they will remain in release code
without warnings.
Because of the expanded code now in Q_ASSERT, the Intel compiler's
optimizer gets thrown: it complains that the non-void function is
failing to return anything, so I had to add two return statements.

Do not automatically add a \n to all messages formatted by
qFormatLogMessage. Some backends require a final newline,
some don't, so it's best to only append it where it's actually needed.
The returned string will be null if the pattern is empty. This allows
to differentiate between the case that the pattern just didn't apply
(empty line is printed), and the case that qSetMessagePattern(QString())
have been called (nothing is printed).

On Windows, the detection changes only by inserting the use of the
environment variable before the existing tests and removing the check on
stderr.
This commit adds logic similar to Windows's: if the application has a
controlling TTY, we'll use stderr. Otherwise, we'll use the system log.
This is technically a change in behavior: previously, we would always
use the system log, unless the environment variable told us not to.
In practice, the behavior doesn't really change: Android and BlackBerry
and systemd-spawned applications are launched with no controlling TTY,
so logging will go to their logging systems.
[ChangeLog][Important behavior changes][Logging (including qDebug and
qWarning)] Log output will now go to the system log (if support for it
was compiled into Qt) if the application has no controlling terminal or
console window. Set QT_LOGGING_TO_CONSOLE to 1 to force logging to go to
stderr.
