adds new option "-Ghost:port" that is equivalent to running "ssh nc host port"

The attached patch allows to use ssh as a remote netcat.

A new flag -Ghost:port activates the feature.

For instance:

 $ ssh foo.bar.com -Gwww.openssh.org:80

redirects local stdio to www.openssh.org 80 through foo.bar.com

It is equivalent to running

 $ ssh nc www.openssh.org 80

but using SSH port forwarding support (and that means that port
forwarding should be allowed on the remote side) instead of a helper
command.

Cheers,
