Conrad Meyer 4ca8c1efe4 KASSERT: Make runtime optionality optional 
Add an option, KASSERT_PANIC_OPTIONAL, that allows runtime KASSERT()
behavior changes.  When this option is not enabled, code that allows
KASSERTs to become optional is not enabled, and all violated assertions
cause termination.

The runtime KASSERT behavior was added in r243980.

One important distinction here is that panic has __dead2
("attribute((noreturn))"), while kassert_panic does not.  Static analyzers
like Coverity understand __dead2.  Without it, KASSERTs go misunderstood,
resulting in many false positives that result from violation of program
invariants.
