Protected access to stream->demux_action_pending

The deadlock was caused by the unprotected use of
stream->demux_action_pending internal variable from play_internal() and from
within the demuxer loop.

Direct access to demux_action_pending is replaced with _x_action_raise() and
_x_action_lower(), which use a mutex for thread safety.
