Split request URI into SCRIPT_NAME and PATH_INFO by Sympa itself

Fix logging of open file error in Config_XML's constructor.

  extra-path of script-URI inproperly, we'd be better to reconstruct them:
  SCRIPT_NAME and PATH_INFO.
  Note that we shouldn't use non-standard CGI environment varialbes such as
  REQUEST_URI.
- Additional environment variable SYMPA_DOMAIN stands for available
  mail domain (a.k.a. "robot").
- If no robot providing web service was found according to client's request,
  error response will be returned.
