opt: allow const arguments.

This need shows up most clearly with opt_usage_and_exit and gcc's
-Wwrite-strings, where string literals become "const char *".  Our
callbacks should take const void *: since we overload the arg field
already (to hold table size) it make sense to turn it into a proper
union.
