General note
This file contains the part that handles File URLs.
File URLs as scheme specific notion of URIs
(RFC2396) may be handled platform independend, but
will not in osl which is considered wrong.
Future version of osl should handle File URLs this
way. In rtl/uri there is already an URI parser etc.
so this code should be consolidated.
