John Polstra 7fd62c59f5 Add support for -Wformat consistency checking between format strings
and their argument lists for the err(3) family of functions.  Note,
I intentionally used __printflike instead of __printf0like for
warnx.  Although a NULL format string is legal for that function, it
doesn't make any sense.
