63f78e41dc tst_qthreadstorage: Fix execution for WinRT
Not putting executables into debug/release subdirectories leads to the
WinRT AppxManifest being overwritten by the wrong configuration. When Qt
is configured with -release for example, it was possible that the debug
manifest (Manifest files are always created next to the target) is
written last and thus contains debug VCLibs as a dependency.

Additionally the test was changed in that way, that the resulting file
system structure (having helper and test application in a "top level"
debug and release folder) is the same structure as in tst_qobject.

309dacedac Atomics: remove requirement for alignment equality with plain types
This was originally added so that you could replace a T with
QAtomicInteger<T> in the same class and still keep ABI. However, for
legacy reasons, on 32-bit x86, types larger than 4 bytes keep an old
1990s alignment of only 4 bytes, but modern std::atomic<T> for those 8-
byte types enforces an alignment of 8 bytes. Therefore, the requirement
to keep alignment is not possible to guarantee.

In other words: you may not replace T with QAtomicInteger<T> or
std::atomic<T> and assume no ABI breakages in all platforms.

This is a requirement to implement atomicity. An 8-byte type aligned to
only a 4-byte boundary could cross a 16-byte boundary or, worse, cross a
cacheline boundary. Crossing the 16-byte boundary could be bad on some
processors, but crossing the cacheline boundary (addresses ending in
0x3C, 0x7C, 0xCC and 0xFC, or 4 out of 64 possible addresses or 6.25%)
is always bad: the CPUs cannot guarantee an atomic load or store
operation.

See also <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71660>.

081c001deb QSemaphore: fix deadlock when the woken up thread wakes up another
When the thread that got woken up by release() is supposed to release()
to wake up another thread, we were deadlocking. This happened because we
cleared the bit indicating that there was contention when the first
release(). Instead of storing a single bit, we now store the number of
threads waiting.

ce08318a46 Add QThreadPool autotest to detect stale threads after tryTake
This test makes sure that we do not introduce a regression where the
threads exited the inner loop over the queue before the queue was
empty. This was triggered by calling tryTake at least maxThreadCount
times, which left the same number of null pointers in the queue
and caused the inner loop to exit too soon for all the threads.

which gives a mostly uniform distribution over the [0, bound)

some that were too ugly for me to understand)

541a031552 tst_QMutex: produce less noise with MSVC
Since MSVC doesn't have <chrono> (according to QT_HAS_INCLUDE), the QSKIP
in the test was printed for every line in the table. Instead, add the
skip in the _data() function.

d23e18189c Skip QThread stress test on Qemu
Qemu uses some memory for each generated thread. This test creates
> 80000 threads and consumes about 10Gb of memory which is too

597d4ff796 QThread: add static create function
In the spirit of std::thread, which takes a function to call and its
parameters, and runs it in a new thread. Since the user might want to
connect to signals, move QObjects into the new thread, etc., the new
thread is not immediately started.

Although technically all of this _should_ be implementable in pure
C++11, there is nothing in the Standard to help us not reinvent all the
plumbing: packing the decay'd parameters, storing them, invoking the
function over the parameters (honoring INVOKE/std::invoke semantics).
std::function does not do the job, as it's copiable and therefore does
not support move-only functors; std::bind does not have INVOKE
semantics.

I certainly do not want to reimplement all the required facilities
inside of Qt. Therefore, the full blown implementation requires C++17
(std::invoke).

In order to make this useful also in pre-C++17, there are two additional
implementations (C++11 and C++14) that support just a callable, without
any arguments passed to it. The C++11 implementation makes use of a
class to store and call the callable (even move-only ones); basically,
it's what a closure type for a C++14 lambda would look like.

An alternative implementation could've used some of the existing
facilities inside QObject::connect implementation that store a functor
(for the connect() overload connecting to free functions), namely:
the QtPrivate::QFunctorSlotObject class. However:

* QFunctorSlotObject does not support move-only callables (see
QTBUG-60339);
* QFunctorSlotObject itself is not a callable (apparently by design),
and requires to be wrapped in a lambda that calls call() on it;
* the moment QTBUG-60339 is solved, we'd need the same handwritten
closure to keep QFunctorSlotObject working with move-only callabes.

So: just use the handwritten one.

The C++14 implementation is a simplified version of the C++11 one,
actually using a generalized lambda capture (corresponding to the
handwritten C++11 closure type).

All three implementations use std::async (with a deferred launch policy,
a nice use case for it!) under the hood. It's certainly an overkill for
our use case, as we don't need the std::future, but at least std::async
does all the plumbing for us.

[ChangeLog][QtCore][QThread] Added the QThread::create function.
