When `127.0.0.1 localhost` is included twice in `/etc/hosts`, such as on some installations of Debian, OpenSMTPD currently fails to start with "address already in use". Fix it by not creating duplicate listeners on for the same DNS entry. Fixes OpenSMTPD#1075 and OpenSMTPD#1106.

When `127.0.0.1 localhost` is included twice in `/etc/hosts`, such as on some installations of Debian, OpenSMTPD currently fails to start with "address already in use". Fix it by checking that no existing listener on the same address and port is configured before configuring another one. Fixes OpenSMTPD#1075 and OpenSMTPD#1106.

When `127.0.0.1 localhost` is included twice in `/etc/hosts`, such as on some installations of Debian, OpenSMTPD currently fails to start with "address already in use". Fix it by only adding listeners for unique addresses returned in a single `getaddrinfo` call. Fixes OpenSMTPD#1075 and OpenSMTPD#1106.

Sometimes
listen on localhostcauses smtpd to listen on 127.0.0.1:25 twice. This reliably happens on Debian when127.0.0.1 localhostis included twice in/etc/hosts.See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976194#17 for details.
