Withdraw patch attachment #2018.

This missive just obsoletes(withdraws) the current variant of the
patch.  We just had a bad network glitch here and, because of it,
ssh-keyscan called the `select()' function in the `packet_read_seqnr()'
function with a NULL timeout value.  Since the read wasn't going to
receive any data because of the glitch ever, it occasionally did one of
those hang forever thingys.  The patch still works if your network
doesn't glitch like ours did albeit very crudely.

It turns out that the original coders of ssh-keyscan missed(?) a call
to the `packet_set_timeout()' function which in turn caused the above
referenced NULL.  I'm in the process of rewriting the patch to include
a "set" call.

FWIW - bugzilla won't let me subit this withour a non-null file.  The
new attachment is a NL.
