crashme(9): Use sysctl mib numbers, not node pointers.

The node pointers are not stable across insertions of siblings,
because they are pointers into arrays that may be reallocated and
moved elsewhere.

XXX Need to audit the tree for other bugs of this class, or change
sysctl(9) so it returns stable node pointers.

crashme: a framework to test kernel faults.

so far, only a basic panic() and null deref nodes are added.
with options DEBUG, one can now use:

   # sysctl -w kern.crashme_enable=1

   # sysctl -w kern.crashme.panic=1
   # sysctl -w kern.crashme.null_deref=1

to trigger a crash.  crashme_enable must be set to 1 before any
of the nodes will be writeable.

supports dynamic additional/removal of crashme nodes.


(obsoletes kern.panic_now, which will be removed later.)
