In qdbus_cast(), qMetaTypeId<QDBusArgument> as well as
qvariant_cast<QDBusArgument> are used. They don't depend
on any template argument of qdbus_cast(), so their
definitions need to be available at function template
definition instead of instantiation time.
But the necessary Q_DECLARE_METATYPE(QDBusArgument)
was at the end of the header, after the defintion of
qdbus_cast(), which is too late for conformin compilers.
Fixed by moving it up just after the QDBusArgument
definition.
Similarly, in tst_qdatetime and tst_qvector, the
Q_DECLARE_METATYPE() for Qt::DateFormat and QVector<int>,
and with it the specialisation of QMetaTypeId<>, were
issued after the first use of meta typing; too late for
conforming compilers.
