UpdateHostKeys fixes:

I accidentally changed the format of the hostkeys@openssh.com messages
last week without changing the extension name, and this has been causing
connection failures for people who are running -current. First reported
by sthen@

s/hostkeys@openssh.com/hostkeys-00@openssh.com/
Change the name of the proof message too, and reorder it a little.

Also, UpdateHostKeys=ask is incompatible with ControlPersist (no TTY
available to read the response) so disable UpdateHostKeys if it is in
ask mode and ControlPersist is active (and document this)

Tweak config reparsing with host canonicalisation

Make the second pass through the config files always run when
hostname canonicalisation is enabled.

Add a "Match canonical" criteria that allows ssh_config Match
blocks to trigger only in the second config pass.

Add a -G option to ssh that causes it to parse its configuration
and dump the result to stdout, similar to "sshd -T"

Allow ssh_config Port options set in the second config parse
phase to be applied (they were being ignored).

     Implement client-side hostname canonicalisation to allow an explicit
     search path of domain suffixes to use to convert unqualified host names
     to fully-qualified ones for host key matching.
     This is particularly useful for host certificates, which would otherwise
     need to list unqualified names alongside fully-qualified ones (and this
     causes a number of problems).
