While it is not recommended by Microsoft to manually exit an
application, currently applications just hang when exiting main().
Instead when QCoreApplication::exit() is called use the CoreApplication
to properly invoke native Exit() and let the application completely shut
down.
Add a warning to notify developer about this non-standard behavior, as
usually the system is supposed to take care of suspending and closing.

The function used a QMap<int,int> to map the %n's to the index
in the args array.
By way of construction, the key was sorted in ascending order
while the values, initially all -1, were later reassigned to be
0...map.size()-1, ie. std::iota().
The only information this data structure stores is therefore
the sorted %n's. For that, a sorted vector is a vastly superior
data structure.
Go one step further and use QVarLengthArray to avoid
allocating any memory for the common case of just a few
placeholders.
As an artifact of the underlying refactoring, the management
of that data structure has been moved to a separate class,

Due to a flaw in the internal API, QXmlStreamReader's internal buffering
would mistake a NUL byte in the input stream for EOF during parsing, but
wouldn't set atEnd == true because it hadn't yet processed all bytes.
This resulted in an infinite loop in QXmlStreamReaderPrivate::parse.
So, instead of returning zero (false) to indicate EOF, return -1 (but in
unsigned form, ~0, to avoid ICC warnings of change of sign). In turn,
this required enlarging a few variables to avoid ~0U becoming 0xffff,
which is a valid QChar (could happen if the input is a QString, not a

Replace the existing code in QProcess that dealt with signaling of child
processes exiting with forkfd and spawnfd. The previous code was
convoluted and hard to maintain, having shown its age in the last
year. I've been running it for a year and a half and the new
implementation is definitely an improvement.
This change replaces support for the QNX Neutrino spawn() call with the
POSIX version. We lose the ability to do setsid(), but we gain quite a
few ioctls() that were done to fill in the file descriptor mapping
structure. That's also the only OS for which we have the ability to
thread-safely chdir() before the call to spawnfd().
Another advantage is that forkfd does not require a dedicated thread
running to handle child processes exiting.

The most common use case for QTextStream::readLine() is reading
a file line by line in a loop. The existing readLine() method
allocates new memory for each line, that results in a loss of
speed. The introduced overload can use already allocated memory.
Besides it allows you to not think about filesystem specifics.
The current QFile documentation suggests a separate way to read
files from /proc filesystem. With this overload it's possible
to use the same idiom in all cases:
QTextStream in(&file);
QString line;
while (in.readLine(&line)) {
process_line(line);
}

The old code fetched QHashData::seed from qt_qhash_seed on every detach.
That is both unnecessary and wrong.
It is uneccessary, because if the detached-from QHashData isn't shared_null,
the seed has already been populated from qt_qhash_seed. It thus suffices to
fetch the seed from qt_qhash_seed only when we detach from shared_null.
It is wrong, because if qt_qhash_seed was changed between the detach from
shared_null and a following detach, d->seed is now different from this->seed,
but detach_helper simply clones the buckets 1:1 from this to d, leaving d
in a corrupt state.
By doing this change, we make QHash robust against on-the-fly changes
to qt_qhash_seed (e.g. for testing, or added security). It also opens up the
option to have API for changing the seed of a given QHash instance after it
has been created (detach, set new seed, rehash).

There are two things fishy in this file:

2. Missing explicit initialization of a member of

the ICE happens in that line. That class itself is quite
smelly, because the address of an object is taken before

The way swapping is supposed to work is:
1. Each type supplies a swap() function or function template in its
namespace. Any good STL implementation will find it there through
ADL. As will the primary qSwap() template.
2. Each use of swap() in Qt, in particular in template code, should
use qSwap() instead of std::swap() or the using+swap-trick, because
qSwap() automatically enables ADL. It also has a sophisticated
conditional noexcept specification that can be used in the
custom swap() functions' own noexcept clause.
This change also allows us to convert implicitly-shared classes'
member-swap functions to noexcept one at a time, because the
specialization will no longer be in conflict with the primary
template regarding exception specifications. The primary's
specification could, of course, be reused here, but it's complex
and if the machinery around it is changed later on, it will not
affect Q_DECLARE_SHARED classes.

To fix, write a new class that acts much like the old QPair<QPointer<>,QByteArray>,

identity, also saves the naked pointer originally passed and uses that for op==

from the RestorableId instance instead of using the parameters directly.
Now, RestorableId holds the QObject* in a QPointer, so the code might have
wanted to detect the object being destroyed as part of the operation, BUT:
a) the operation is a read-only one, and b) the code didn't check for

The previous change (SHA 82c2118c) to provide better
than 1ms accuracy for timers on QNX is not safe.
According to the docs, ClockCycles is not guaranteed to
return consistent information if called from different
CPUs. While this can be addressed by locking the thread
to a single CPU, you wouldn't want to do that here.
On some systems (e.g. BB10) the behavior is extremely bad
since ClockCycles only has 32 bits of precision. This
results in overflows in the calculations making short
timers run very slowly (16ms timers were around 1s). Also
ClockCycles wraps in under three minutes causing even
more problems.
I've talked to the kernel developers and there is currently
nothing that will give you better than 1ms accuracy. An
individual program could use ClockCycles to calculate more
accurate times if they want.
It's not clear to me what benefit one would get with
increased accuracy. Unless I've missed something, these
times are only used to calculate timeouts for calls such as
select. These timeouts will themselves have the same
resolution as clock_gettime provides so the increased
accuracy would appear to be for naught.

We cannot use override in the Q_OBJECT macro, so tell Clang not to warn
about our lack of use of the keyword in the three virtuals that Q_OBJECT
overrides when the user uses Q_DECL_OVERRIDE in their own functions.
We can't use Q_DECL_OVERRIDE for two reasons:
1) because that would trigger the warning in any and all virtual
overrides the user may have in their own class (and most of Qt)
2) because when Q_OBJECT is used in QObject, it's not overriding
anything -- it's the base declaration
For #2, we could add a different macro exclusively for QObject that moc
would expand, but it's unnecessary work.

QVariant(LLONG_MAX / 2) < QVariant(Q_UINT64_C(0)).
