patch for removing staled credentials in .Xauthority

ssh does not remove its entries in xauthority file and makes it grow.
Lookup in too big a file might take lots of time, especially when the
machine is not connected to the Internet or if the file stores
hostnames that do not exist any more.

There are probably many ways how to fix this issue. I am attaching a
patch for openssh 4.7p1 we are using in openSUSE, that attempts to
address it.
