Implementation of QFileSystemEngine::copyFile() uses CopyFile2() as if
it is CopyFile() function, but CopyFile2() returns HRESULT, not BOOL.
So the success should be checked by "SUCCEEDED()" instead of "!= 0".
Current implementation does exactly the opposite because S_OK == 0.

The store to guard in the inner function's critical
section was not synchronized-with the load at the
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.

To avoid data corruption and possibly undefined behavior, this patch
makes QWindowsPipeWriter::write() take a QByteArray, which it keeps alive

emit that signal shortly after the thread starts. Before this patch,
QThreadData::threadId was initialized only by QThreadPrivate::start(),

On some operating systems, tzdata files carry the Local Mean Time (LMT)
for the city in question, which better represents how time was tracked
before standard, hourly timezones were introduced in the early 20th
century. The test was asking for the data for 1653-02-09 and assumed
that it would find the first Central European Time (CET) rule, which
Germany didn't start using until 1893-04-01.

This fix allows us to remove the blacklist that had been applied to this
test without investigation. It wasn't related to OpenSUSE, aside from
the fact that OpenSUSE tzdata carries the LMT data.

In addition to pen events being handled as tablet events, we create
touch events. Same principle is used on other platforms as well. This
allows devices as Surfaces to use the pen with Qt applications.

Furthermore, the first update event does not have to be a press event,
as in a pen has proximity values describing a move without touch, but
also the HoloLens uses touch points as permanent pointer devices. They
all send an exit event once released or out of range. Hence, clean up
the internal touchpoint hash when the touch device is gone, not on
release.
