UWP also supports SwitchToThread. The usage of Sleep(0) was a leftover
that was forgotten when porting to desktop Window's approach of handling
threads.

For winrt we cannot rely on the fact, that QThread::current will be called
from the correct thread for the first time. The application's main entry
point creates a suspended thread and starts it right afterwards. At that
moment, other functionality (QLoggingRegistry for example) might have
called QThread::current, which set the wrong thread as the main thread. In
order to avoid this situation, the main thread is explicitly set in
QCoreApplication's constructor.

On Windows, the error code to be used with qErrnoWarning is not errno,
but Windows's GetLastError(). Obviously, right?
So don't pass errno to it, just let it get the error message straight
from qt_error_string(), which will use GetLastError().

We cannot inline methods of QThreadPrivate because QThreadData has to
be declared before. The global QThreadData needs to be accessible to
QThreadData::clearCurrentThreadData(), and QAdoptedThread::run() has to
be moved inside the #ifndef QT_NO_THREAD block as run() doesn't exist
in the stub and Q_DECL_OVERRIDE would be wrong.
We also fix the QThreadData::current() method to take and use the same
parameters as in the non-stub case.

[ChangeLog][Visual Studio] Reverted a change that caused static
binaries compiled with Visual Studio 2015 to crash on start-up. Note
that this does not apply to Visual Studio 2017 static binaries, even
though the crash stack traces are very similar: with 2017, the problem
is compiler regression and requires updating to version 15.8 for the
fix.

The original design for the 64-bit futex had the token count replicated
in the high part. But the constructor wasn't setting it. This is one of
the issues I had noticed when investigating QTBUG-66875, but didn't need
to address since the the fix I ended up applying in commit
081c001deb75fa38385d3ff8cbbdb4f788529133 made that unnecessary: the high
part only had the number of waiters.
Unfortunately, when commit f502270c0f06daba75c1da381bd1658d81aa7bba
brought back the token count in the high part, I failed to correct that
problem. As a consequence, every QSemaphore that was initialized in the
constructor to a non-zero value would eventually deadlock.
This commit fixes that oversight.

This time, the issue was that we could race a wait and a wake. A multi-
token waiter would not notice that the number of tokens changed because
it only performed a fetch-and-OR, then waited on the high part which did
not change. That means the futex_wait() would succeed, when we wanted it
to have failed.
So we have to bring back a portion of what commit
081c001deb75fa38385d3ff8cbbdb4f788529133 removed: we need to keep both
the token count and the waiter count in the high word.

After including windows.h, interface is a define that expands to
"struct" (unless WIN32_LEAN_AND_MEAN is defined). This name is
used as a normal identifier in multiple places within Qt.
This has already been worked around in a number of places
(in e.g. 3ba61d9baa569ea69e41a943981680c09c521ff7 and
786d23bb4966b6697ac04c43158e2312d898e133).
After qrandom.h was included in <QtCore/QtCore>, this header
implicitly includes <random>. In libc++ on windows, this header
then transitively includes windows.h, exposing the clash with
the name "interface" in even more locations than before.
For cases within qtbase internals, it could also alternatively be
handled by defining WIN32_LEAN_AND_MEAN while building QtDbus, but
for occurrences in public headers, the undef trick needs to be
used.

The fixes included adding missing '!' characters to qdoc comment
markers, correct misspelled words, adding documentation for an
anonymous enum type, and replacing Q_QDOC with Q_CLANG_QDOC.
There remain 12 qdoc link warnings in QtBase.
