Introduce a transaction mechanism that gives the ability to read the
data atomically. Current implementation supports transactions for both
types of devices. For sequential devices, it records the whole input
stream during transaction. For random-access devices, device position
is saved when transaction starts. If an error occurs, the application
may be able to recover the input stream by rolling back to the start
point.
Also, QIODevice::peek() was rewritten to make use of transactions
internally. The replacement of QIODevicePrivateLinearBuffer by
QRingBuffer is closely entangled with that, which makes it unfeasible
to do separately.
Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.
[ChangeLog][QtCore] Added QIODevice's startTransaction(),
commitTransaction(), rollbackTransaction(), isTransactionStarted()
functions to support the read transactions.

This fixes the problem as long as we have C++ 11's semantics for
in-function statics. The Q_GLOBAL_STATIC_WITH_ARGS() is a non-trivial
wrapper whose destructor gets unloaded with the plugin, leading to a
crash-on-exit if the global it wraps outlives the plugin. The plain
(in-function) static manages to avoid this by avoiding the wrapper.
As the static was only needed in one place, this proves a sufficient
solution to the plugin-unload problem *in this case*.

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

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.
