sshd accepted fingerprint logging

[Eldon Koyle]

Currently, LogLevel must be set to VERBOSE to see the fingerprint of an
accepted key, and the default LogLevel is INFO.  Since this is useful
security information, I would like to propose that the 'Accepted
publickey' message be modified to include the fingerprint of the
accepted key.  Is this a reasonable solution?

Here is an example log snippet with LogLevel VERBOSE:

Men often believe -- or pretend -- that the "Law" is something sacred, or
at least a science -- an unfounded assumption very convenient to governments.
