If you would like connected UDP, I won't object to you implementing

OK. I'll set these patches aside until I have time to look into adding
connected UDP support.
That's not completely necessary... the one-shot + TCP changes just
make it nicer when the local rpcbind is not listening. Without these,
the cases where the rpcbind daemon isn't running, or doesn't support
rpcbind v3/v4 and the kernel was built with CONFIG_SUNRPC_REGISTER_V4,
will cause some delays before failing, but otherwise shouldn't be a
problem.
I think you can drop the patch to change rpcb registration to go over
TCP for now unless you already have a CUDP implementation you are
happy with.
I know a lot of folks are waiting for IPv6 support to appear, and I
don't want this detail to hang it up.
