Hash :3d462a97 Message :Move banner exchange to sshd-auth process
Previously, exchange of the initial SSH- banners was performed
by the privileged sshd-session monitor. This moves it to the
unprivileged sshd-auth subprocess, removing ~200 LoC from the
monitor's privileged attack surface.
The monitor gains a new "setcompat" RPC to allow sshd-auth to
inform it of bug compat flags picked up from the client's banner.
