Log Message:
Retire xen/x86/intr.c and use the new xen specific glue in x86/x86/intr.c

The purpose of this change is to expose the x86/include/intr.h API
to drivers. Specifically the following functions:

   void *intr_establish_xname(...);
   void *intr_establish(...);
   void intr_disestablish(...);

while maintaining the old API from xen/include/evtchn.h, specifically
the following functions:

    int event_set_handler(...);
    int event_remove_handler(...);

This is so that if things break, we can keep using the old API until
everything stabilises. This is a stepping stone towards getting the
actual XEN event callback path rework code in place - which can be
done opaquely behind the intr.h API - NetBSD/XEN specific drivers that
have been ported to the intr.h API should then work without
significant further modifications.
