Disable transport name resolution by default.

Disable transport name resolution by default.

Modern hosts typically open many more TCP and UDP connections than in
years past.  For an example opening a popular news site in a web browser
can easily trigger dozens of separate connections. At the same time our
services file has accumulated a lot of cruft over time. As a result
transport name resolution is a bunch of lies.
