Based on review comments, I've changed how the NFSv4 callback server
starts its listener. If the kernel has IPv6 support, it will start an
AF_INET6 listener; otherwise it will start an AF_INET listener.
Subsequent lockd IPv6 patches already work this way, it turns out, so
I've updated the patch in this subseries that adds a helper to display
NLM IPv6 addresses. If an IPv6 address is a mapped IPv4 address, it
will be displayed as a dotted-quad instead of as an IPv6 address. This
should cause the helper to display IPv4-style addresses on systems that
use only IPv4, even though the listener is AF_INET6. This effects
only error and debugging messages.
I should revisit other areas (already integrated, and in pending
patches) which display presentation format addresses, to ensure they
follow suit.
