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).
