I'm not sure I like the approach. I would prefer to introduce a second
panic() function with explicit file/line number / function argument.
panic() itself could be replaced by a macro calling that new verbose
panic function, maybe under an option.

I think it is time for KASSERTMSG and friends to just adopt C99 variadic
macros with the associated dropping of a pair of (). That involves more
code churn though.
