xine-lib/src/post, branch 1-rc5

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

2004-05-29T14:45:25+00:00

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* the reimplementation of status() in the upmix plugin is obsolete

Correct port status call.

If we change bits,rate or mode, we have to also provide our own status call.

Remove the center channel from the upmix.

2004-05-17T15:10:20+00:00

It just causes the left and right channels to sound like they are coming from the center,
so one looses any good left/right effects.
