This partially reverts commit e486d69133.
It broke too many users, even though all of them deserved to be broken.
The new functionality will be provided by differently-named functions,
where possible (problem: equality operators).
I did not revert the fix for the off-by-one error in
tst_qtextdocumentfragment.cpp.
I also didn't revert the change in the inequality relational operators,
since for all strings s1, s2 and s2' where s2' is s2 truncated at the
first NUL, s1 < s2 ⟺ s1 < s2' (since NUL < c for any c != 0), and,
trivially, for ≤, >, ≥, too. This does not hold for = and ≠, of course,
since "foo\0bar" ≠ "foo".

For almost the whole of its life time, 'realname' has the same
prefix, but the old code used the same string-builder expression
to construct it over and over again. If QStringBuilder would
re-use the capacity of the LHS object, that would boil down to
just a bit more copying of characters than necessary. But
assigning a QStringBuilder expression to a QString works by
implicit conversion of the QStringBuilder expression to a
QString, followed by move-assigning the new QString into the
old.
The new code keeps the common prefix around, resetting
'realname' to that prefix with truncate, only appending the
varying suffixes. In this way, one memory allocation per
assignment is saved (ignoring a potentially required capacity
increase in one of the appends here), and also some out-of-line
QString dtor calls, since op+=(QString&, QStringBuilder...)
doesn't create a temporary QString.
Also saves ~1KiB in text size on optimized GCC 4.9 Linux AMD64
builds.

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

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.

QStack does allow.
Since a lot of places where QStack is used use at least some of

Since the use of std::stack with the default std::deque increases
