jhb 7ea4fab234 - 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.
