1. Changed Request.run from request_line arg to deconstructed args: method, path, query_string, and protocol. 2. Moved HTTP protocol checking from _cprequest to _cpwsgiserver. What was cherrypy.response.version is now cherrypy.request.protocol (tuple form of SERVER_PROTOCOL). request.version and response.version attributes removed. _cpwsgiserver now writes out server.protocol, not SERVER_PROTOCOL (which is a misnomer, it really should have been REQUEST_PROTOCOL). 3. path unquoting was also moved from _cprequest to _cpwsgiserver (like most other WSGI servers). 4. New test for absoluteURI in the Request-Line.
