- trim historical header and drop ABI version for pcre

Update PCRE to 8.32
Introduces the UTF-32 library pcre32
Bump PORTREVISION in dependent ports

Fix build with clang, by:
- setting USE_CSTD=gnu89
- unnesting a nested function definition (patch-src__util.c)

Note that this code may be unsafe or yield bogus results where the sizes of
size_t/int or long/int do not match, such as amd64. This causes tons of
warnings with clang and should be reasonably easy to find.

Feature safe: yes

Convert to new options framework

New port: mail/smtp-gated

        This software block SMTP sessions used by e-mail worms and
        viruses on the NA(P)T router. It depends on netfilter
        framework of Linux, or ipfw on FreeBSD.

        It acts like proxy, intercepting outgoing SMTP connections
        and scanning session data on-the-fly. When messages is
        infected, the SMTP session is terminated. It's to be used
        (mostly) by ISPs, so they can eliminate infected hosts from
        their net work, and (preferably) educate their users.
