Starts a mount_operation, mounting the volume that contains the file location. When this operation has completed, callback will be called with user_user data, and the operation can be finalized with g_file_mount_enclosing_volume_finish(). 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.
