[readconf.c readconf.h roaming_client.c ssh.1 ssh.c ssh_config.5]
[sshconnect.c sshconnect.h]
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).
