QMessageLogger: initialize QT_FATAL_xxx cooperatively between threads
The use of function-local static implied there was a guard variable to
perform a thread-safe initialization (a critical section). We don't need
that: we can just use a plain QBasicAtomicInt and cooperatively
initialize, in parallel. This way, the QMessageLogger code does not need
to check the status of the guard variable before every access to the
atomic, which would be an atomic access before the atomic access.
