separate the two semantics of querying a port's status with a NULL stream;

before, NULL could mean two things: no stream at all or a stream that does not
want to be addressed; now the latter is represented by the new XINE_ANON_STREAM
resulting changes:
* the status() functions now behave differently for NULL and XINE_ANON_STREAM
  (as the commentary always implied, but this was not the case, so post
  plugin rewiring went wrong, because it relies on the status() function)
* the NULL_STREAM defines in audio_out and video_out are obsolete
* update the function comments in the headers
* update the post plugin rewire functions to use the status() functions to
  check, if the old port was opened and handle the new one accordingly;
  this makes open_count obsolete
* change all post plugins accordingly (mostly using XINE_ANON_STREAM instead
  of NULL)
additional change:
* the status() function of audio port now returns the bits/rate/mode values
  of the input and not the output; this is more likely to be what a post plugin
  wants
* the reimplementation of status() in the upmix plugin is obsolete
