A Qt5 program writing a null QTime() using setVersion(QDataStream::Qt_3_3),
and then a Qt3 program reading that, would lead to a weird QTime,
with isNull=false, isValid=false, hour=1193, minute=2, second=47, ms=295.
This commit restores interoperability, by writing out the expected value
(0) for a null QTime rather than the -1 value used by Qt4 and Qt5.

Push conversions from pthread_t to Qt::HANDLE and back into functions.
The casts that were being used didn't work for the unusual 64-bit
pointer/32-bit int combination that QNX is using for 7.0. HANDLE ends
up as a 64-bit pointer and pthread_t ends up as a 32-bit integer. g++
considers the precision loss when converting from the 64-bit pointer
to the 32-bit integer an error. Better to have the casts hidden in

The old code iterated through one QJsonObject and looked up the key
in the other, comparing the values. It had linearithmic complexity,
and created one QString 'key' per element.
Since the entries in a QJsonObject are lexicographically ordered,
we can, however, just walk through the two objects in lock-step and
compare corresponding entries (at the same index) with each other.
Doing so saves O(N) QString creations and QJsonObject::value()
calls, and makes operator== linear in the number of elements.

There are several ways to detect a dead process on Windows. Some of

The current implementation of stale lock detection is based on the

Allow tmpfs filesystems to be reported, as they're often usable by the
user, mounted in /tmp and in /run (the fs for $XDG_RUNTIME_DIR).
But disallow anything whose device is not a pathname. This catches most
of everything else that wasn't specifically tested for before, like
virtual fuse filesystems, like GVFS.

We were using direct loading and operator=, which for everything except
std::atomic was very relaxed. But std::atomic<T *> defines the direct
access to actually be the least relaxed possible, under the idea that if
you didn't know any better to use a member function, you probably need
the most protection.
So use Ops::load and Ops::store.

The C and C++ standards say it's undefined whether the preprocessor
supports macros that expand to defined() will operate as an ifdef.
Clang 3.9 started complaining about that fact.
One solution was to change QT_SUPPORTS to check for zero or one, which
means we need to change the #defines QT_NO_xxx to #define QT_NO_xxx 1.
The C standard says we don't need to #define to 0, as an unknown token
is interpreted as zero. However, that might produce a warning (GCC with
-Wundef), so changing the macro this way is not recommended.
Instead, we deprecate the macro and replace the uses with #ifdef/ndef.

The store to guard in the inner function's critical

start of the function:
T1 T2
guard.load()
mutex.lock()
guard.load()
d = new Type
guard.store()
guard.load()
// use d
mutex.unlock()
The use of d in T2 does not synchronize with
the write to d in T1 -> data race -> UB.
Fix by storing with release memory ordering,
so that the guard.load() in T2 synchronizes
with the guard.store() in T1.

The MSVC STL warns when passing naked pointers as non-bounded
iterators to algorithms such as std::equal and std::copy, in
an attempt to inform users that the range specified by that
iterator has an implicit minimum size that the caller of the
algorithm must ensure is met:
warning C4996: 'std::_Equal1': Function call with parameters that may be unsafe - \
this call relies on the caller to check that the passed values are correct. To \
disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to \
use Visual C++ 'Checked Iterators'
When building Qt, as well as when building user projects with
qmake (cf. 0a76b6bc7f), we
globally disable this warning (with -D_SCL_SECURE_NO_WARNINGS),
but since we started using STL algorithms in public headers (e.g.
in qvector.h), users get this warning in their own projects now,
unless they, too, define said macro. But such a requirement is
against the Qt policy to have headers that are warning-free as
much as possible.
The suggested way of fixing this warning is to wrap the naked
pointer in a stdext::unchecked_array_iterator before passing it
to the algorithm, cf. examples in
https://msdn.microsoft.com/en-us/library/ttcz0bys%28v=vs.120%29.aspx
or, together with the capacity-made-explicit, in a
stdext::checked_array_iterator.
To avoid ifdefs for platforms that don't have these extensions
(which, incidentally, for the unchecked case, includes MSVC 2012),
wrap the calls in macros.
The end game here is to drop -D_SCL_SECURE_NO_WARNINGS, at least
for public headers, even though this commit also adds the wrapper
to implementation and private header files.
An alternative to the wrapper would have been the version of
std::equal that takes four iterators. However, that is a C++14
library feature, while this version of Qt still needs to compile
with a C++98 compiler, and, more importantly, there isn't, and
never will be, a corresponding 4-iterator version of std::copy.

Note that ARC translation units can be combined with non-ARC translation
units, so Qt and the QMacAutoReleasePool class can still be used in
