preproc: fix varadic macros, add conditional comma operator
Fix the (severely broken handling of) varadic macros.
Add a conditional comma operator "%,". This expands to a comma unless
followed by a null expansion of some sort, which allows suppressing
the comma before an empty argument (usually varadic, but not
necessarily.)
