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.
