Matthias Clasen d1c3745b07 Try harder to handle accelerators involving virtual modifiers
This patch changes GDK to add all matching virtual modifiers in
the state field of the key event. The corresponding GTK+ change makes
use of a new GdkKeymap function to map virtual modifiers back to
real modifiers and detect conflicts while doing so.

This should fix bug 603190 and bug 427409.
