XKB: Redirect actions defunct with Gtk3 (XInput?) 

When redirect actions are used with Gtk3, Gtk3 complained about
events not holding a GdkDevice.  This was caused by device IDs
not being set for redirect actions.

More seriously, Gtk3 did not receive state changes redirect
actions might specify.  This was because event_set_state in
dix/inpututils.c accesses the prev_state field, but the changes
for the redirect action were only put into the state field.
