[Greg Hudson via RT]

Use binresvport_sa when creating RPC handles

Make clnttcp_create, clntudp_bufcreate, svctcp_create, and
svcudp_bufcreate work with unbound IPv6 sockets using bindresvport_sa
and other socket helpers.  For caller-supplied sockets, call
getsockname to determine the address family we should attempt to bind.

[ghudson at mit.edu: clarified commit message, minimized code changes,
used socket-utils.h helpers, fixed fallback find on bindresvport
failure, restored getsockaddr call to get port after binding]
