  Modified files:
    sys/i386/isa         atpic.c 
  Log:
  - Add an IMEN_MASK macro that returns the 8-bit bitmask of an atpic
    interrupt source.
  - Only do an outb() to the PIC to clear a bit in imen if the bit is set.
  - Add a NUM_ISA_IRQS macro to replace uglier
    'sizeof(array) / sizeof(member)' expressions along with a CTASSERT() to
    ensure that the macro is correct.
