Can't keep the call to ungrabGesture() in the loop,
because it removes the current element from the very
hash being iterated over. Instead, inline the call
and optimize based on the context:
- don't remove element by element, but clear the
hash completely at the end.
- drag the check for QGestureManager::instance()
out of the loop.
- drop the check for presence of the key in the
hash, since it would be always true.

It's a version of fromConfiguration() that returns the QSslContext

The idea here, of course, is to use QSharedPointer<T>::create(),
which co-locates the refcount with the payload in a single memory
allocation, instead of QSharedPointer<T>(new T), which causes
two allocations.

[ChangeLog][Important Behavior Changes] Starting with Qt 5.7, Qt
requires a C++11 compiler with support for C++11 atomics. This affects
user code too: Qt headers no longer compile with a C++98 compiler. The
minimum compiler versions for this release are:
* Clang 3.4 (found in XCode 5.1)
* GCC 4.7
* Microsoft Visual Studio 2012

QSimplexConstraints are held in QList everywhere, yet one
single function, getGraphParts(), used a temporary
QLinkedList. It did so because the function repeatedly
walks the list, erasing elements from it until no more
elements have been removed.
Thus, in O-terms, QLinkedList is the correct choice here.
Sadly, O-notation completely ignores the per-element cost,
and this is where QLinkedList suffers. By the time a QList
has shifted all of its elements left once, the QLinkedList
probably has just finished allocating its first node.
So, use a QList instead.
That, however, turns the it = erase(it) loop quadratic, so
re-formulate the processing part as a lambda and use
std::remove_if. Don't even erase until we know how many
items to erase.
As a benefit, we save the final conversion of the remaining
items back to a QList, and we can use QList::op+ to build
the initial list, reducing the number of allocations
performed by that container to one.
Also saves ~770b in text size on optimized GCC 5.3 Linux
AMD64 builds.

We need to have reasonable paths for loading icons and such things, just
as in any other Unix GUI environment. However there is some concern that
it would be too much of a behavior change if there was a theme by default,
so for now it's required to set the env var: QT_QPA_PLATFORMTHEME=generic
That works because QGuiApplicationPrivate::createPlatformIntegration() reads
the env variable and passes platformThemeName to init_platform().
Step 3 in init_platform() does not find a theme plugin by that name
(because QGenericUnixTheme is statically linked via libQt5PlatformSupport.a).
Then in step 4 it iterates the given platformThemeName plus any which
were returned from QPlatformIntegration::themeNames() (which in our case
will be an empty list) and calls createPlatformTheme() with each of
those, until something is returned. So,
QEglFSIntegration::createPlatformTheme() will be called with the
value of the QT_QPA_PLATFORMTHEME env var, and
QGenericUnixTheme::createUnixTheme() will create the generic, KDE or Gnome
theme depending on that value.

Introduce a transaction mechanism that gives the ability to read the

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
