New configuration scripts for Cygwin

Hi,

I have attached two new shell scripts `ssh-host-config' and
`ssh-user-config' which will replace the script `ssh-config'
in the next Cygwin OpenSSH release.

Could somebody with write access please remove

	contrib/cygwin/ssh-config

from the OpenSSH repository and add these two attached files
instead?

The third attached file is the diff for contrib/cygwin/README.

Thanks in advance,
Corinna

There was an S/Key change that I commited tonight.  Could you verify that
auth1.c around like 325 if that is the correct location for that little
CYGWIN, or if it should go after the root checking case.  Assuming that
the root check is even valid under Cygwin.

Thanks.
