Subject: Commit of stuff that's been sitting in my tree for a while.

Highlights include:
- New low-level trap code from NetBSD.  The high level code still needs a lot
  of work.
- Fixes for some pmap handling in thread switching.
- The kernel will now get to attempting to jump into init in user mode.  There
  are some pmap/trap issues which prevent it from actually getting there though.
