[PATCH RFC 0/3] Avoid well-known port numbers

[Chuck Lever <chuck.lever@oracle.com>]

Following up on https://bugzilla.linux-nfs.org/show_bug.cgi?id=320 .

Here's a possible way to get libtirpc to avoid well-known port
numbers when a caller requests a dynamically-assigned port. This
compiles without complaint, but I haven't tested it yet. I'm
interested in comments on the approach.

I understand that Fedora 28 is closing soon. It would be nice to
see a fix for this issue in libtirpc for that release.
