fixes #41 Move DNS out of tcp transport

This moves the DNS related functionality into common code, and also
removes all the URL parsing stuff out of the platform specific code
and into the transports.  Now the transports just take sockaddr's on
initialization. (We may want to move this until later.)

We also add UDP resolution as another separate API.
