Renames file to the specified display name.
The display name is converted from UTF-8 to the correct encoding
for the target filesystem if possible and the file is renamed to this.
If you want to implement a rename operation in the user interface the
edit name (G_FILE_ATTRIBUTE_STANDARD_EDIT_NAME) should be used as the
initial value in the rename widget, and then the result after editing
should be passed to g_file_set_display_name().
On success the resulting converted filename is returned.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
