Log Message:
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.)
