>Description:
Since I maintain a ports tree overlay, I find it easier to update ports from a centralized patched copy instead of worrying about patching separately on each machine. None of the available ports tree update methods are useful for this.

The attached patch adds an rsync update mechanism, requiring only RSYNC_UPDATE and PORTS_RSYNC_SOURCE defined in /etc/make.conf.

Tested on 9.1-RC1 and 8.2-RELEASE.
