Marcel Moolenaar 6d33366c74 Update for the KDB framework:
o  ksym_start and ksym_end changed type to vm_offset_t.
o  Make debugging support conditional upon KDB instead of DDB.
o  Call kdb_enter() instead of breakpoint().
o  Remove implementation of Debugger().
o  Call kdb_trap() according to the new world order.

unwinder:
o  s/db_active/kdb_active/g
o  Various s/ddb/kdb/g
o  Add support for unwinding from the PCB as well as the trapframe.
   Abuse a spare field in the special register set to flag whether
   the PCB was actually constructed from a trapframe so that we can
   make the necessary adjustments.

md_var.h:
o   Add RSE convenience macros.
o   Add ia64_bsp_adjust() to add or subtract from BSP while taking
    NaT collections into account.
