syslog-ng: detect disabled IPv6 on loopback and fallback to IPv4 Binding in default to IPv6 is preferable but it can be disabled in kernel and that prevents syslog-ng to start. This setup should not be that common but syslog is very important service and should survive that. This introduces new plugin defining source generator `network_localhost`. This is used instead of original network source. Signed-off-by: Karel Kočí <cynerd@email.cz>
