code cleaning, and prepare for internal review

Re-adapt the Spec-compliant solution (instead of Lib-compliant solution).
  Thus no more 100% deferred interface.
Rename EWSGI_RESPONSE into EWSGI_RESPONSE_BUFFER
Added in extra/response-as-result/  an copy/paste from the implementation of Paul's proposal (not up to date with Paul's spec). But this is mainly for information and tests.
Removed part of the ewsgi/specification interfaces ... to be able to test EWSGI compliant library against the pure specification (experimental).
Renamed most of the GW_... into EWSGI_...

 		3.2. The Script-URI
 
-		   The 'Script-URI' is defined as the URI of the resource
+		      script-URI = <scheme> "://" <server-name> ":" <server-port>
-		   identified by the metavariables. Often, this URI will be the
+		                   <script-path> <extra-path> "?" <query-string>
-		   same as the URI requested by the client (the 'Client-URI');
-		   however, it need not be. Instead, it could be a URI invented
-		   by the server, and so it can only be used in the context of
-		   the server and its CGI interface.
-		   
-		   The Script-URI has the syntax of generic-RL as defined in
-		   section 2.1 of RFC 1808 [7], with the exception that object
-		   parameters and fragment identifiers are not permitted:
-		   
-			<scheme>://<host><port>/<path>?<query>
 
-		   The various components of the Script-URI are defined by some
+			where <scheme> is found from SERVER_PROTOCOL, <server-name>,
-		   of the metavariables (see section 4 below);
+			   <server-port> and <query-string> are the values of the respective
-		   
+			   meta-variables.  The SCRIPT_NAME and PATH_INFO values, URL-encoded
-			script-uri = protocol "://" SERVER_NAME ":" SERVER_PORT enc-script
+			   with ";", "=" and "?"  reserved, give <script-path> and <extra-path>.
-						 enc-path-info "?" QUERY_STRING
 
-		   where 'protocol' is obtained from SERVER_PROTOCOL,
-		   'enc-script' is a URL-encoded version of SCRIPT_NAME and
-		   'enc-path-info' is a URL-encoded version of PATH_INFO. See
-		   section 4.6 for more information about the PATH_INFO
-		   metavariable.
-		   
-		   Note that the scheme and the protocol are not identical; for
-		   instance, a resource accessed via an SSL mechanism may have a
-		   Client-URI with a scheme of "https" rather than "http".
-		   CGI/1.1 provides no means for the script to reconstruct this,
-		   and therefore the Script-URI includes the base protocol used.

+This library introduce the notion of router and handler
+The Router manages the association between URI,URI template and Handler
+The Router is in charge to route/dispatch a request to one of the Handler according to the URI and how the Handler is mapped in the Router.
+
+Common usage
+
+router: REQUEST_ROUTER
+hello_handler: REQUEST_HANDLER
+
+create {REQUEST_URI_TEMPLATE_ROUTER} router.make
+create {REQUEST_AGENT_HANDLER} hello_handler.make (agent handle_hello)
+
+router.map ("/hello/{name}", hello_handler)
+router.map_agent ("/hello/{name}", agent handle_hello)
