security/openssh-portable

[Grzegorz Blach]

I (maintainer of security/openssh-portable) need one or two days to 
review GSI patch and other patches which are available for openssh-5.9.
But repocopy security/openssh-portable to security/openssh-portable58
and upgrade security/openssh-portable to 5.9 sound reasonable for me.

Beginning from FreeBSD 9.0 openssh in base system has applied HPN 
patches, so I think it isn't a good idea to maintain port which is very 
close to system's openssh. In this case simply use openssh from base system.
