Log Message:
- Simplify debugger/procfs reference counting of processes. Use a per-proc
  rwlock: rw_tryenter(RW_READER) to gain a reference, and rw_enter(RW_WRITER)
  by the process itself to drain out reference holders before major changes
  like exiting.
- Fix numerous bugs and locking issues in procfs.
- Mark procfs MPSAFE.
