Improve safeness of QMetaType::registerType.

This internal function is abused by some modules to create dynamic
types in metatype system. In Qt5 more non-optional arguments were added
to the function and to keep temporary source compatibility an overload
was created.

QMetaType code assumes that every known type has properly defined basic
operations like creation and destruction. Setting a helper function
pointer to null value is asking for a crash, because the code doesn't
check for that value, the null pointer may be called.
