9002f7f47a Fix documentation for ReuseAddressHint on Unix.
The code says (for Q_OS_UNIX)
if ((mode & QAbstractSocket::ShareAddress) || (mode & QAbstractSocket::ReuseAddressHint))
    socketEngine->setOption(QAbstractSocketEngine::AddressReusable, 1);
so clearly ReuseAddressHint does the same as ShareAddress, which is: setting SO_REUSEADDR.

0355345398 winrt: Flush the system event queue when adding/removing windows
This has only been identified by WACK for Windows 10.

QWinRTWindow::setVisible adds a Window to the screen and immediately
tries to set the native visibility. This only works when the system
events are handled immediately. While this is the case most of the time,
certification tests revealed that this is not always the case. We have
to flush before setting the element visibility.

14e43c8f42 winrt: Fix API usage certification
According to MSDN Tls* is inline replaced by Fls* on Windows (Phone) 8.1
and beyond.
However, this does not seem to be the case for Windows 10. An
application links against Tls* and the certification step fails due to
using non-allowed APIs.

Hence we do the inline replacement manually. QThreadStorage and QThread
tests continue to work, so it seems to be an oversight by Microsoft.

becbffe291 winphone: Properly close the application
When shutting down an application on Windows Phone the SceneGraph tries
to create an offscreen surface to render into. If there is no offscreen
surface available, it creates a new native window and tries to hide it.
As the native event loop is about to shut down, creation fails and
exceptions are raised. Instead we create a vanilla
QPlatformOffscreenSurface. The SceneGraph recognizes it as such and can
handle a proper cleanup on its own.

Furthermore removing the suspend/resume handler in the destructor of
QWinRTIntegration fails for Windows Phone as the application object
itself does not accept this anymore. Hence skip this part for this
platform.

2b1f01426c WinRT: Fix application shutdown
Do not create a dummy eglDisplay when the global static is constructed.
This causes ANGLE to wrongly set some internals, which breaks usage of
EGL_PLATFORM_ANGLE_ENABLE_AUTOMATIC_TRIM_ANGLE as the attribute map
might be empty after calling eglGetPlatformDisplayEXT. Furthermore
initialize() assigns a new display to it without terminating the old
one. This way, the internal suspend handler in ANGLE (Trim11.cpp) will
be added to the application.

The suspend handler is not invoked when an application suspends though.
Reason being that the handler needs to be added from inside the Xaml
thread. As we cannot control this inside ANGLE, we will call
eglInitialize inside the Xaml thread and hence get the suspend event
properly.

89293e6b19 Make DST-transition test more general.
Widen its interval (to work in more TZs) and test spring as well as
autumn.  Anywhere that does have a DST transition probably has it
between August and December; and there's no benefit to using a narrow
window.

There's also no sense skipping the test if we don't know there's a DST
transition: the test should still work, it just won't be testing
anything (about DST transitions).

Combine date and time checks into date-time checks, so that, when one
of them fails, QCOMPARE lets us know how the other changed, too.

1e2b42523f Fix UB in tst_QObject::disconnectDoesNotLeakFunctor()
If CountedStruct is passed a GetSenderObject object,
it will attempt to call a member on it from within
its own destructor.

That works usually quite well, but in this test case,
which tests for function object leaks when a connection
is torn down because the sender object is destroyed,
the destruction of the CountedStruct happens when all
connections are severed in ~QObject. At that point,
what used to be a GetSenderObject instance no longer
is one and the call into one of its member functions
invokes undefined behavior.

Fix by making QObject::sender() public by a using
declaration instead of a wrapper function.

Found by UBSan:

aca299715f QDirModel: replace a QStack with a std::stack
std::stack, based on std::vector, tends to be more efficient that
QStack, based on QVector, but, crucially, it is an actual stack,
so doesn't allow, say, iteration or insertion in the middle, which
QStack does allow.

Since a lot of places where QStack is used use at least some of
those non-stack features, protect this instance which doesn't, yet,
from becoming another such site.

Since the use of std::stack with the default std::deque increases
text size by almost 1K, and a vector makes a perfectly good stack,
use std::vector as the backing container (which std::stack, being
a container adapter, allows easily).

Saves ~0.5KiB in text size on optimized GCC 5.3 Linux AMD64 builds.

282f15feaa rewrite qtAddToolEnv()
the primary purpose is making env var prepend mode work for unset
variables on windows. this is achieved by using a conditional and delayed
variable expansion. however, the latter is disabled by default and can
be locally enabled only in batch files. therefore, write wrapper scripts
and substitute them for the actual commands. we do this also on unix,
both for consistency and simply because the commands look much less
confusing.

this change is slightly backwards-incompatible, as invoking
qtAddToolEnv() multiple times on the same command will now make a total
mess. also, invoking it on a command that contains 'make' macro
expansions isn't a good idea, so testcase.prf needed an adjustment. the
function is an undocumented internal, so Nobody Should Care (TM).

this also reverts 80ebedecf9, as it's obsolete now.

6f69a313bd Fix offset and size for native child rtt widgets
Render-to-texture widgets that are native children may have a non-zero
offset telling the position within the top-level widget. The size is
usually different (smaller) than the tlw's size as well.

An unfortunate optimization attempt led to ignoring the size for native
children with offset (0, 0). This resulted in interesting rendering
artifacts whenever such widgets were placed in the top-left corner of
the toplevel. This is now corrected.

f5291bf8b4 Fix UB in tst_QObject::noDeclarativeParentChangedOnDestruction()
If QObjectPrivate::declarativeData is set, it is
in various places in Qt expected to point to a
QAbstractDeclarativeDataImpl, from which ownedByQml1
is unconditionally read.

In noDeclarativeParentChangedOnDestruction(), the
declarativeData pointer is, however, set to a local
QAbstractDeclarativeData instance, which, being an
empty class, has size 1 and alignment 1.

Depending on the compiler's idea of bit field order,
this code either read uninitialized data from the
dummy object, or else some random stack memory outside
any (valid) object.

What caught UBSan's attention, though, was the
difference in alignment between the two classes:

  src/corelib/kernel/qobject.cpp:917:9: runtime error: member access within misaligned address 0x7fffc9cf706f for type 'struct QAbstractDeclarativeDataImpl', which requires 4 byte alignment

Fix by providing a properly initialized object of the
correct type.
