Clang 3.8's undefined-behavior sanitizer checks that the
declared type of the object is a base class of the
dynamic type of the object on each access to a member
of a class type.
It therefore requires the typeinfo for these types,
which for polymorphic types is emitted in the TU where
the vtable is emitted, too.
QDBusConnectionPrivate is a polymorphic non-exported class,
so this failed at link-time. Ditto for the other case.
Fix by autotest-exporting the classes.
Also, where applicable, de-inline the dtors, so the
vtable (and typeinfo) are pinned to one TU, and the
ctor, just because it's the correct thing to do.

This pertially reverts commit 3ec57107ce
and brings back the hack to prevent the DLL from being unloaded. It
should have been enough, but we've got reports that it's still causing
trouble. Since it causes not much harm to keep the DLL loaded (worst
case scenario is that QtDBus and QtCore remain loaded after a plugin
gets unloaded), we'll keep it.
Note: Microsoft is aware that their way of killing threads on process

This function sends D-Bus messages directly (in huntAndEmit), so it
should only be called from the QDBusConnectionManager thread. Somehow, I
missed this in the Qt 5.6 refactoring of QtDBus.
Being called in the wrong thread means that there's a visible behavior
change compared to Qt 5.5: if the user code sent a method call or method
return/error and then emitted a signal, we'd have two threads racing to
send the D-Bus messages. This was observed in Telepathy-Qt code: certain
signals arrived before a method return, even though they were clearly
emitted by a queued QMetaObject::invokeMethod.
In addition to that, we have has an internal problem (though not
observed): the libdbus-1 timer and socket callbacks would be called in
the wrong thread and we no longer have protection against that.
Unit testing not possible since this is a race condition.

This commit also reverts fecaa6aae8.
The Microsoft documentation says _beginthreadex and _endthreadex are
used to initialize the C/C++ runtime and are necessary when linking to
libcmt(d).lib (that is, when using the -MT or -MTd options). For regular
builds linking against the .dll runtime, there should be no impact.
Inspection of the CRT source code which gets installed with Visual
Studio or Windows SDK proves that.
It's preferable to use CreateThread directly as _endthreadex will try to
call FreeLibraryAndExitThread, which can cause a deadlock if we try to
wait for the thread to exit from a global destructor.
For -MT builds, since there can be no DLLs, it's not a problem to
continue to use _beginthreadex and follow Microsoft's recommendation.
