Subject: [PATCH 18/23] rpcinfo ip_ping: clean up client ping/create/destroy
The code doing the actual RPC NULL calls and the handling of
VERSMISMATCH was a bit convoluted. We would destroy and re-create
the client handle, and sometimes the associated file descriptor
would be closed and sometimes not.
Clean this up by introducing a new function ip_ping_one, which
does the actual NULL call to the indicated program version without
destroying the client handle, ever.

Subject: [PATCH 19/23] rpcinfo: introduce new helper function ip_getclient
This function tries to obtain the address of a given host/program/version,
using the specified protocol (one of udp or tcp), and create a client
handle for it.
This loops over all netconfig entries (according to the order given
by netpath and the config file), and tries to resolve the hostname,
and obtain the address using rpcb_getaddr.

Subject: [PATCH 20/23] rpcinfo: make -t/-u options support IPv6 addresses,
too
Currently, rpcinfo supports two ways to test whether a given
service is alive.
For IPv4 hosts, you can use -u and -t. But for IPv6, you need
to use "rpcinfo -a" and specify the host through a universal
address, which is fairly inconvenient.
This patch modifies ip_ping to allow using -u and -t for IPv6
addresses and hosts as well.

Subject: [PATCH 22/23] Make rpcinfo -p support IPv6 addresses, too
While this is not strictly necessary (you can use "rpcinfo <hostname>" instead),
some older scripts may rely on rpcinfo to work with just about any hostname.
Let's be gentle with them. It doesn't cost us much.
