Marc Eshel reports that using the -v command line option on the
sm-notify command stopped working after nfs-utils 1.2.2, when IPv6
support was added. If nfs-utils is built without IPv6 support, it
still works. Marc specified a hostname with a single A record.
smn_bind_address() must construct a bind address with the same
family as the RPC socket's protocol family. Add an AI_V4MAPPED hint
so an appropriate IPv6 bind address is constructed even if -v
specifies an IPv4 presentation address, or a hostname with only IPv4
mappings.
We still use an IPv4 bind address if IPv6 support is compiled out or
the host does not support IPv6.
