As an example of using mod_sofia's gateway parameter `contact-params`
we'd used the value `tport=tcp`. Looking around, it's clear this has
misled people into believing you can specify `tport=tcp` to make the
gateway use TCP or `tport=tls` to make the gateway use TLS. This does
not work.
The actual contact parameter is named `transport` rather than `tport`,
and you shouldn't use `transport` in `contact-params` because we
automatically add a `transport` to the Contact: based on the value of
`register-transport` (even if the gateway is set to not register).
It's clear why this would be confusing, so we'll just remove this as
an example.
