Avoid UB in moc generated code
Introduce a Q_OFFSETOF() macro that uses the optional support of
offsetof() for non standard layout types and disables the
corresponding compiler warnings. All our supported compilers
support offsetof() on non standard layout types.
Use the macro to do the offset calculations required in moc
generated code to replace a manual offset calculation that
was dereferencing a null pointer.
