Kurt Griffiths fa1d69c803 feat(Request): Refine the new protocol, port, and netloc attrs (#978) 
See also PR #917

This patch does the following:

    * Moves the docstring for the deprecated "protocol" alias to be
      below the new, recommended "scheme" attribute.
    * Changes the type of "port" to an int to be consistent with the
      parse_host() utility function.
    * Expand the "port" docstring.
    * Add a docstring for "netloc".
    * Implement "uri" in terms of "netloc".
    * Handle default port in the try block, since that it is not
      necessary to do so in the case that SERVER_PORT is used.
    * In the tests, inherit from TestCase instead of the deprecated
      TestBase class.
    * DRY up the tests.
    * Test the new attributes with both the HTTP/1.0 and HTTP/1.1
      protocols.
