Given the crazy defines of stuff like free, it seems like a good idea to have
a rule that no headers should be included after plperl.h with
PG_NEED_PERL_XSUB_H defined.  It's not like there's not other chances of of
pulling in malloc.h from within pg_wchar.h somehow.

It's a bit ugly to have the mb/pg_wchar.h in plperl.h instead of
plperl_helpers.h, but ...
