This is commit two of a two commit set:

Reduce supported syslog-ng ports to the latest syslog-ng supported by
our upstream, oniedentity.com. Upstream does not officially support
earlier releases. This commit reduces unofficial support expectations
and allows us to rely totally on upstream for support.

This commit copies syslog-ng from syslog-ng329, which contains the full
history of the syslog-ng family of ports. Whereas syslog-ng became a
meta-port many moons ago to support multiple versions of syslog-ng in
the tree. We will only support syslog-ng supported by our upstream.

Discussed wth: Peter Czanik (CzP) <peter.czanik@oneidentity.com>
