- Move manipulation of td_intr_nesting_level out of assembly interrupt

  vector stubs and into the C functions they call.
- Move disabling and EOIing of interrupt sources out of PIC driver entry
  points and into intr_execute_handlers().  Intr_execute_handlers() only
  disables a source for an interrupt if it is a stray interrupt or has
  threaded handlers.  Sources with fast handlers no longer disable (mask)
  the source while executing the handlers.
- Move the setting of clkintr_pending into intr_execute_handlers() and set
  the variable for any interrupt source with a vector of 0.  (Should only
  be true for IRQ 0.)  This fixes clkintr_pending in the NO_MIXED_MODE
  case.
- Implement lapic_eoi() and use it to implement ioapic_eoi_source().
- Rename atpic_sched_ithd() to atpic_handle_intr() since it is used to
  handle all atpic interrupts and not just threaded ones.
