Subject: [PATCH 08/13] Fix the behavior when specifying the -h option

Currently, when specifying the "-h" option, rpcbind will try to create
sockets for all specified addresses, plus the loopback address. However,
it will only register its programs on the last SVCXPRT created, which
will usually be the first address specified via -h.

This patch fixes this problem by introducing a new function that creates
the socket *and* registers all programs, and use that from the while
loop.
