This is more consistent with the rest of the API.

The new name is more consistent with the rest of the API.

It doesn't look very useful as a public function.

This is more readable and makes it easier to reorder URLProtocol
members.

There's no particular reason to pollute the namespace with a typedef for
it.

This way is possible to have simple micro-server act like

ffmpeg -i file.nut -vcodec copy -acodec copy -f nut tcp://foo:1234?listen

This way people will not get surprises regarding the current configure
behaviour and contributors will have a guideline on what is expected.
