Terminating a thread that we don't have full control over might leave
mutexes or critical sections locked, ending up with an application that
can't allocate memory or open new windows.
Also, if terminating of the thread would fail (which the code tried to
handle), then deleting the QThread anyway would have triggered the
assertion that we don't delete a running thread in ~QThread.
So simplify this code: wait simply returns true if the thread isn't
running anymore, no need for the double-check. Leave the thread running
and leaking if it is stuck somewhere in Windows APIs while executing the
native dialog.

As a driveby, it also includes a minor fix for the lance testing tool:

[ChangeLog][QTestLib] QCOMPARE now evaluates toString() on its
arguments lazily, speeding up the general case where the comparison
doesn't fail. This is true for the QCOMPARE functionality provided
by Qt. If you specialized qCompare() for your own types, then you
need to change its implementation in line with Qt's own qCompare()
specializations in order to enable this feature.
[ChangeLog][QTestLib] QCOMPARE calls with nullptr argument(s) will
now print the actual and expected values upon failure.
Previously it was not like that because of the compareHelper()
overload in qtestresult.cpp that treated the presence of
nullptr-arguments as a reason to ignore formatFailMessage() call.
New implementation does not have this check, and correctly
executes formatFailMessage() for all arguments.
Note that the qCompare() overloads that call QTestResult::compare()
internally were not affected by this patch, because they already
defer toString() invocation until the comparison fails.
Some numbers, collected against shared release developer build.
I checked how this change affects the test execution. The idea was
to pick some tests for types that do not have a specific
QTestResult::compare overload, so I picked a couple of QByteArray
tests.
The comparison is done by running a test 10 times and taking the
average execution duration, as reported in the log.

Before: 15.6 ms

Add support for blocking sockets on secondary threads and on the main
thread with asyncify. This extends the support for websockify tunneled
TCP sockets, which was previously limited to async sockets on the main
thread.
Blocking sockets support is implemented by emulating select() on top
of emscripten's socket notification support. This is requires synchronization
between the blockee threads and the main thread, since we get socket
notification callbacks on the main thread. The synchronized state is held
in g_socketState where the main thread registers socket readiness state and
blocking threads register themselves.
Blocking using asyncify on the main thread is similar to blocking on
a secondary thread, with the exception that the main thread suspends
with qt_asyncify_suspend() instead of waiting on a wait condition.

"Conditional jump or move depends on uninitialised value(s)"
due to m_exclusive being uninitialized.
Not sure to what extent this fix matters in practice, the crash
turned out to be caused by something else outside QT. But anyway
it seems good to initialize m_exclusive like other things, in the
constructor, and it helps avoiding such warnings from valgrind,
that will make it easier to detect other problems using valgrind
or similar tools.
Amends ac8a1787eb where it looks
like initialization of this member was simply forgotten.
