NetBSD/sys/ddb/db_print.c
ad cd6b1c8f08 Make ddb compile and work in userspace. Mostly this is comprised of three
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
  and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.
