moving dh-group-exchange forward.

[Bill Sommerfeld <sommerfeld%sun.com@localhost>]

We need a new revision of this document to resolve IESG concerns and to 
adapt to new process guidelines.

The new IETF tools team has a status page up for this document at:

http://tools.ietf.org/wg/secsh/draft-ietf-secsh-dh-group-exchange/

for nits, see:

http://tools.ietf.org/wg/secsh/draft-ietf-secsh-dh-group-exchange/draft-ietf-secsh-dh-group-exchange-04.nits.txt

for IESG concerns, see:

https://datatracker.ietf.org/public/pidtracker.cgi?command=print_ballot&ballot_id=1151&filename=draft-ietf-secsh-dh-group-exchange

it appears that the document is for the most part acceptable; it just
needs to be rebuilt to current format standards (3667/3668) and have the
current copyright notice replaced.
