registerUriScheme
Registers @uri_func and @parse_name_func as the #GFile URI and parse name lookup functions for URIs with a scheme matching @scheme. Note that @scheme is registered only within the running application, as opposed to desktop-wide as it happens with GVfs backends.
When a #GFile is requested with an URI containing @scheme (e.g. through g_file_new_for_uri()), @uri_func will be called to allow a custom constructor. The implementation of @uri_func should not be blocking, and must not call g_vfs_register_uri_scheme() or g_vfs_unregister_uri_scheme().
When g_file_parse_name() is called with a parse name obtained from such file,
Return
true if @scheme was successfully registered, or false if a handler for @scheme already exists.
