This is not only good for move-only types, but for any type which

We can add basic constructors now on all supported platforms, and can
make initialization consistent on all platforms, choosing undefined
as the default.
Note this changes behavior on gcc and clang builds, but is consistent
with pre-c++11 gcc and clang builds and with msvc.
[ChangeLog][QtGui][QRgba64] The default constructor on Clang and GCC
builds now no longer initializes with 0s, but leaves the value
uninitialized. This is consistent with MSVC behavior and pre-C++11

The code compared a QString* with a QString, which only compiled
because the QStringRef(const QString*) ctor was implicit. We're going
to fix that, and it's nice to see that the change exposes bugs like
this one.
The fix is to deref the QString* argument, which we know from previous
checks to be non-nullptr, to enable normal QString/QString comparison.

It's a Qt 3 compatibility vehicle, and as such inherits the now-alien
property to distinguish empty and null strings. Particularly worrisome
is the following asymmetry:
QString("") == QString::null // false
QString("") == QString(QString::null) // true
Instead of fixing this behavior, recognize that people might use it as
a weird way to call isNull(), albeit one that once was idiomatic, and
simply deprecate everything that deals with QString::null.
[ChangeLog][QtCore][QString] QString::null is now deprecated. When
used to construct a QString, use QString() instead. When used to
compare to a QString, replace with QString::isNull().

return __atomic_compare_exchange_n(&_M_i, &__i1, __i2, 0, __m1, __m2);

Fix by explicitly passing the failure orders corresponding to the
success orders, as specified by the standard:
relaxed → relaxed
release → relaxed
acquire → acquire
acq_rel → acquire
(cf. http://en.cppreference.com/w/cpp/atomic/atomic/compare_exchange).

Commit fb376e0fcc removed an array that
facilitated returning the names of built-in types, to avoid the jump tables
from the switch statement. This commit brings it back but makes the array a
compile-time constant string offset table.
The array is created by way of a set of C++11 constexpr functions, so we
require that compiler feature. I've tested that MSVC 2015 does support
it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled
for that too. The only compiler left out is MSVC 2013.
If we didn't need to support MSVC 2015, this could have been written
more simply with C++14 relaxed constexpr.
This also adds unit tests to confirm that QMetaType::typeName() does
return null when we said it would. We're testing QMetaType::User-1
(which we'll likely never use) and QMetaType::LastWidgetsType-1 to
select something inside the range of the built-in types.

Both SPDY and HTTP/2 work with a single qhttpnetworkchannel (and this means one
socket per qhttpnetworkconnection). Normally, HTTP/1.1 connection is using up to 6
channels/sockets though. At the moment a failure to negotiate SPDY/HTTP/2 leaves us
with a downgraded HTTP/1.1 connection (with only one channel vs. default 6).
Since we initialize channels (and establish connections) in a 'lazy' manner
it's ok to pre-allocate all 6 channels and then either use 1 (if SPDY/HTTP/2
indeed was negotiated) or switch back to 6 in case of failure.

QWindowsWindow::handleResized would call isFullScreen_sys which checks
if the window's screen geometry matches the one of the window. When
switching back from fullscreen, Windows will have set the geometry to
fill the next window, but we don't switch QScreen until later in that
function, inside handleGeometryChange. This would result in our window
to take the whole screen geometry, but the FullScreen state wouldn't
be transferred to the new screen.
Fix the issue by using screenForGeometry and check if we are fullscreen
on any screen.
Also make sure that we check the validity of m_savedFrameGeometry when
restoring after a screen remove, since we would previously restore to an
area not covered by any screen anymore.
