Prompted by Coverity CID 11720 (allegedly recently new in dev but
long-standing in 5.6).  Even assuming the class is used correctly -
test initialize() and only use if that succeeded - the destructor
would have passed uninitialized arguments to munmap() and ioctl().

Noticed a double close along the way: it's been fixed on dev but
should have been fixed in 5.6, too.  Documented why ioctl() failure in
switchToGraphicsMode() should at least do no harm.

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.

trying to connect a signal to an object moved to that thread and then
emit that signal shortly after the thread starts. Before this patch,
QThreadData::threadId was initialized only by QThreadPrivate::start(),
which meant that we were racing that initialization with this check in
QMetaObject::activate:

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.
