Although Qt declares its minimum supported OS version to the compiler
and linker, the OS ignores this information when loading shared
libraries, so instead of failing with a useful error message, the
program will simply crash at runtime. This attempts to bring that
failure as early in the lifecycle as possible, and provide a better
error message as well.

... as it has outlived its original purpose:
Qt3 implementation on X11:
void QApplication::flush() { flushX(); }
void QApplication::flushX() { if (appDpy) XFlush( appDpy ); }
Qt4 implementation on X11:
Did nothing when QApplication::flush() was called (the flush()
overrides in {unix,glib} event dispatchers with empty bodies).
In Qt5 this function somehow has been repurposed (inconsistently)
to do what QCoreApplication::sendPostedEvents already does:
QAbstractEventDispatcher::flush() = 0;
=> QCocoaEventDispatcher::flush() {}
=> QEventDispatcherCoreFoundation::flush() {}
=> QIOSEventDispatcher (does not override ::flush())
=> QEventDispatcherGlib::flush() {}
=> QPAEventDispatcherGlib (does not override ::flush())

=> QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush())
Whatever this function was doing on macOS in Qt3 and Qt4 also has been
dropped in Qt5. It appears that the other event dispatchers in Qt5 that
have overrides for flush() have simply copy-pasted this logic.
Clearly the documentation of QCoreApplication::flush() is outdated and
has nothing to do with the actual implementation in Qt5.
This function is rarely used in Qt5 sources. It should be safe to remove
the calls to QCoreApplication::flush() from Qt source code, as this
function has been doing nothing on most platforms anyways. Repurposing
it even broke handling of posted events (see QTBUG-48717).

The MSVC STL warns when passing naked pointers as non-bounded
iterators to algorithms such as std::equal and std::copy, in
an attempt to inform users that the range specified by that
iterator has an implicit minimum size that the caller of the
algorithm must ensure is met:
warning C4996: 'std::_Equal1': Function call with parameters that may be unsafe - \
this call relies on the caller to check that the passed values are correct. To \
disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to \
use Visual C++ 'Checked Iterators'
When building Qt, as well as when building user projects with
qmake (cf. 0a76b6bc7f), we
globally disable this warning (with -D_SCL_SECURE_NO_WARNINGS),
but since we started using STL algorithms in public headers (e.g.
in qvector.h), users get this warning in their own projects now,
unless they, too, define said macro. But such a requirement is
against the Qt policy to have headers that are warning-free as
much as possible.
The suggested way of fixing this warning is to wrap the naked
pointer in a stdext::unchecked_array_iterator before passing it
to the algorithm, cf. examples in
https://msdn.microsoft.com/en-us/library/ttcz0bys%28v=vs.120%29.aspx
or, together with the capacity-made-explicit, in a
stdext::checked_array_iterator.
To avoid ifdefs for platforms that don't have these extensions
(which, incidentally, for the unchecked case, includes MSVC 2012),
wrap the calls in macros.
The end game here is to drop -D_SCL_SECURE_NO_WARNINGS, at least
for public headers, even though this commit also adds the wrapper
to implementation and private header files.
An alternative to the wrapper would have been the version of
std::equal that takes four iterators. However, that is a C++14
library feature, while this version of Qt still needs to compile
with a C++98 compiler, and, more importantly, there isn't, and
never will be, a corresponding 4-iterator version of std::copy.

It's urgent to fix the issue that on Android, it became impossible
to interact with any widget or MouseArea which handles only mouse
events but not tablet events, using the stylus, because stylus events
are sent only as QTabletEvents. Before 5.6 (change
01d78ba86a) they were sent as
touch events, and mouse events were synthesized from those. Whereas
on other platforms, every QTabletEvent is followed by a synthesized
QMouseEvent.
This fix proceeds in the direction that event synthesis should be done
in cross-platform code so that platform plugins don't have to repeat it,
following the same pattern as for touch->mouse synthesis. Just as
in that case, the application can disable it, and the platform plugin
can also report that it's unnecessary for Qt to do the synthesis
because the platform already does.
So QTBUG-51618 is fixed, but QTBUG-47007 requires us to remove the
tablet->mouse synthesis from all platform plugins, because the plugin
does not know whether the tablet event was accepted or not, so it does
not have enough information to decide whether to synthesize a mouse
event. Synthesis has been unconditional until now, which contradicts
what the documentation says: the mouse event should be sent only if
the tablet event is NOT accepted. We can now gradually make this
promise come true.
[ChangeLog][QtCore][Tablet support] A synthetic mouse event will
no longer be sent after every QTabletEvent, only after those which are
not accepted (as documented).

This is caused by QCoreApplication::init() being called from the
QCoreApplication ctor, calling virtual functions on Q*AppPrivate,
which happen to attempt, in this case, to emit QGuiApp signals.
At that point in time, the QGuiApplication ctor has not entered
the constructor body, ergo the object is still a QCoreApplication,
and calling the signal, as a member function on the derived class,
invokes UB.
Fix by cleaning up the wild mix of initialization functions used in
this hierarchy. The cleanup restores the
1. Q*ApplicationPrivate::Q*ApplicationPrivate()
2. Q*ApplicationPrivate::init(), calling each base class'
init() as the first thing
two-stage construction pattern commonly used elsewhere in Qt to make
sure that the public class' object is fully constructed by the time
each level's Private::init() is called.

On Apple platforms the directory is actually called "PlugIns".
Plugins could previously be loaded on OS X by coincidence, but
if the system is using an HFS+ Case Sensitive filesystem (and this
is ALWAYS the case on iOS-like operating systems), the case
mismatch would cause plugins in an application bundle not to be

This patch makes sure that all events posted using Qt on top of the
GLib event loop have the loopLevel counter incremented.
This is done since Qt depends on the fact that all deleteLater() calls
are issued within the scope of some signal handler (in other words,
triggered by the chain sendEvent() -> notifyInternal2()).
There is a side effect though: in the conditions affected by this
patch, that is deleteLater()s issued within a glib event handler for
example, manually calling processEvents() or sendPostedEvents() with
or without the QEvent::DeferredDelete flag has the same effect, and
deferred deleted events are always processed.
While this is not a currently working feature which the patch breaks,
this side effect seems to be difficult to avoid without separating
sendPostedEvents() and processEvents() into a public and a private
method, in order to detect when they are manually called.
Such change could perhaps be done for Qt6.
An autotest for QTBUG-36434 is also included.
Autotesting for QTBUG-32859 seems to be more challenging in this
