daemon: look up client-supplied hostname lazily

Look up canonical hostname and IP address using getaddrinfo(3) or
gethostbyname(3) only if --interpolated-path or --access-hook were
specified.

Do that by introducing getter functions for canon_hostname and
ip_address and using them for all read accesses.  These wrappers call
the new helper lookup_hostname(), which sets the variables only at its
first call.
