We want to be able to use the netx.Network (and RealNetwork
implemementation) outside of tests, without linking "testing".
So split out the non-test stuff of nettest into its own package.
We tend to use "foox" as the convention for things we wish were in the
standard library's foo package, so "netx" seems consistent.

values, and to eventually detect leaked connections in tests. (Later
the memory network will register a Cleanup on the TB to verify that
everything's been shut down)

Not buying wifi on a short flight is a good way to find tests
that require network. Whoops.
