Now all Qt sequential containers consistently provide reverse iterators.
The associative ones, by way of not returning std::pair from op*, can't
just use std::reverse_iterator. They would miss .key() and .value() methods.
So that has to wait for 5.7.
The reverse versions of the new key_iterators can also just use
std::reverse_iterator, but I'm afraid that after bikeshedding over
keyRBegin() vs. rKeyBegin() vs. reverseKeyBegin() vs. rkbegin()
vs. krbegin() (<-- of course, what else?), it would anyway be too
late for 5.6, so defer, too.
[ChangeLog][QtCore][QLinkedList/QSet] Added rbegin(), crbegin(), rend(), crend(),
and reverse_iterator and const_reverse_iterator typedefs.

A QAbstractSocket can be close()'d at any time, independently of its
current connection state. being closed means that we cannot use it to
read or write data, but internally it might still have some data to
send or receive, for example to an http server. We can even get a
connected() signal after close()'ing the socket.
We need to catch this condition and mark any pending data not yet
written to the socket for resending.

If QTimer::singleShot() is used with a functor callback and a context
object with different thread affinity than the caller, a crash can
occur. If the context object's thread is scheduled before
connecting to QCoreApplication::aboutToQuit(), the timer has a change
to fire and QSingleShotTimer::timerEvent() will delete the
QSingleShotTimer object making the this pointer used in the
connection invalid. This can occur relatively often if an interval
of 0 is used.
Making the moveToThread() call the last thing in the constructor
ensures that the constructor gets to run to completion before the
timer has a chance to fire.

The explanation is in the code comment. Ever since QDBusConnections
began being processed in a separate thread, we were relying on the fact
that the main thread didn't begin processing its event queue until the
second event got posted (the event loop only exits after it has finished
processing all pending events). We had a race between the main thread
starting its processing, at which point it decides which is the last
event it will process, and the QDBusConnectionManager thread posting the
second event.
This is very fragile code, since it depends on the behavior of
QDBusConnectionPrivate (how it stores the signal relays in a hash) and
that of QHash with duplicate keys. This only works because the hash
key between the two connections is the same (it's only dependent on the
method name and interface name). If we ever begin using something that
isn't the same between "control" and "p", then with QHash's randomness,
we'll be racy again.

Most processors have carry flags which they set on addition overflow, so
it's a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version.
Tested to compile on:

x86 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta
x86-64 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta

PowerPC 64 GCC 4.9, Clang 3.6*
SPARC Clang 3.6*
SPARCv9 Clang 3.6*
[*] supports the intrinsics
If the compiler does not offer a way to detect an overflow, we do it by
hand. For unsigned additions, that's easy, since the C++ language
specifies the behavior of the overflow. That's also the reason why this
code is implemented only for unsigned integers.
For the multiplication, if the compiler does not support widening
multiplications, we do it with a division instead. This is necessary for
GCC < 4.5 and compilers not compatible with GCC or MSVC.
