Enhance fujifs to have more posix file type functionality.

fujifs functions now automatically handle allocating of FujiNet N:
devices behind the scenes and return a handle when opening a file or
URL. This allows keeping track of state locally that is needed to be
able to allow opening of more than one file at a time.
