branches:  trunk

description:
port to userspace.  this needs db_user.h, stddef.h, stdbool.h and not
promlib.h.  put db_read/write_bytes() under _KERNEL.

XXX: for now, provide an empty db_machine_command_table[].

XXX2: this file puts a lot of it under #ifdef DDB, but i'm not sure
why this is done.  for now it makes it easier to port to userspace :)
