Prefer diffie-hellman-group14-sha1 (2048 bit) over
diffie-hellman-group1-sha1 (1024 bit).

Due to meet-in-the-middle attacks the effective key length of
three key 3DES is 112 bits. AES is stronger and faster then 3DES.

Prefer to delay the start of compression until after authentication
has completed. This avoids exposing compression code to attacks
from unauthenticated users.

My agent exposes both conventional keys and certs (ecdsa-sha2-nistp256-cert-v01@openssh.com) and I want dropbear to be able to use the former.

Add SSH_CLIENT environment variable

Since the x.org rework, X has been installed into standard paths and not
its own random prefixes.  I think it's time we update the default paths
accordingly.

Try without identifying current user

Small change that warns the user if the current user cannot be identified rather than aborting.  This came in handy when I put dropbear on a dlink that did not have a true user environment.  Falling back on the "-l" option and user@ options works just fine as a client.  The only implication I found is that the -J option will fail ungracefully without a known own_user.
