        src/sys/arch/xen/include: evtchn.h
        src/sys/arch/xen/x86: xen_intr.c xen_ipi.c
        src/sys/arch/xen/xen: evtchn.c xen_clock.c

Log Message:
Change event_set_handler() to take the target CPU parameter. If ci is NULL,
  event_set_handler() will choose the CPU and bind the event.
  If ci is not NULL the caller is responsible for binding the event.
Use a IPI xcall to register the handlers if needed.
pull in a hack from x86 to force pirq handlers to be mpsafe if registered at
a level != IPL_VM. This is for the com at isa interrupt handler, which
registers at IPL_HIGH and has to way to tell it's mpsafe (taking
KERNEL_LOCK at IPL_HIGH causes deadlocks on MP systems).
