Add Q_COREAPP_STARTUP_FUNCTION macro.
This is necessary for initializing things in a library, which require
a QCoreApplication instance (unlike Q_CONSTRUCTOR_FUNCTION, which runs
before that). Example use cases: KCrash (segv handler), and KCheckAccelerators
(debugging tool triggered by magic key combination).
