Cleanup: moved parsing of '!' operators from cidr_match.c
to dict_cidr.c. Files: util/cidr_match.[hc], util/dict_cidr.c,
util/match_ops.c.

Cleanup: made parsing of '!' operators in regexp and pcre
tables consistent with cidr tables. Files: util/dict_regexp.c,
util/dict_pcre.c.

Cleanup: integer wrap-around detection in the MySQL and
PostgreSQL clients. This is totally non-critical because
Postfix strings are size-limited by design. Files:
global/dict_mysqql.c, global/dict_pgsql.c.

Documentation: dnsblog.

Documentation: postsuper(1) manpage text for multiple -[dhH]
options.  File: postsuper/postsuper.c.

Cleanup: Postfix SMTP server local IP address and port
attributes in the policy delegation protocol (attribute
names: server_address, server_port), in the Milter protocol
(macro names: {daemon_addr}, {daemon_port}) and in the
XCLIENT protocol (attribute names: DESTADDR, DESTPORT).
