  Log:
  Change the x86 interrupt code to suspend/resume interrupt controllers
  (PICs) rather than interrupt sources.  This allows interrupt controllers
  with no interrupt pics (such as the 8259As when APIC is in use) to
  participate in suspend/resume.
  - Always register the 8259A PICs even if we don't use any of their pins.
  - Explicitly reset the 8259As on resume on amd64 if 'device atpic' isn't
    included.
  - Add a "dummy" PIC for the local APIC on the BSP to reset the local APIC
    on resume.  This gets suspend/resume working with APIC on UP systems.
    SMP still needs more work to bring the APs back to life.
  
  The MFC after is tentative.
