Bugfix (introduced: Postfix beta): the never-used function
mvect_free() attempted to free memory that it has not
allocated. File: util/mvect.c.

Cleanup: existing if/endif support for pcre and regexp
tables, in preparation for new if/endif support for cidr
tables. Files: util/dict_regexp.c, util/dict_pcre.c.
