Better support for unicode path and values.

Added WSF_REQUEST.percent_encoded_path_info: READABLE_STRING_8
    to keep url encoded path info, as it is useful for specific component

The router is now using WSF_REQUEST.percent_encoded_path_info
    since URI_TEMPLATE are handling URI (and not IRI)
    this fixes an issue with unicode path parameters.

This should not break existing code, and this fixes various unicode related issues related
   to PATH parameter and path info
   but also any component using file names.

(required EiffelStudio >= 7.2)
