Log Message:
Get rid of xen-specific ci_x* interrupt handling:
- use the general SIR mechanism, reserving 3 more slots for IPL_VM, IPL_SCHED
  and IPL_HIGH
- remove specific handling from C sources, or change to ipending
- convert IPL number to SIR number in various places
- Remove XUNMASK/XPENDING in assembly or change to IUNMASK/IPENDING
- remove Xen-specific ci_xsources, ci_xmask, ci_xunmask, ci_xpending from
  struct cpu_info
- for now remove a KASSERT that there are no pending interrupts in
  idle_block(). We can get there with some software interrupts pending
  in autoconf XXX needs to be looked at.
