  Log:
  - 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.
