* Began implementation of a LOGONCE flag for debug pipe.

* IBM-PC:
  * getBspId:
    * Migrated the code to detect the LAPIC paddr to lib LAPIC.
    * Fixed a potential bug in the event that getBspId is called twice.
  * i8259a:
    * IdentifyActiveIrq: Returns UNIDENTIFIABLE if the pin list isn't
      yet allocated.

* CPU Trib:
  * Implemented initialize() for internal members.
  * BSP CPU's ID and bank are now detected in getBspId(), before the
    main CPU detection stretch.
