* src/input/decoder.c: don't let the decoder/packetizer fifo grow too much because this leads to a steady increase in memory useage when the data isn't consumed quickly enough. (not the best fix, but should be better than nothing)

 Initial path by Philippe Van Hecke (philippe DOT vanhecke AT belnet DOT be)

Added a RTP (New) stream outpu method for the rtp sout module. Still lot of work in this dialog box.

  - added fourcc for SNOW and DTS.
  - added 'qscale' (fixed quantizer scale - VBR) and 'strict' (standard compliance) encoding options.

* vout_Control implemented for macosx
* position slider fixed
* p_input manage loops fixed (buttons, playstatus etc)
* float on top works again
* visual filters work
* deinterlace filter selection broken
* fullscreen button is not being updated atm
* potential deadlocks between intf thread and vout thread???
* the window title might not always be updated.

OSX devs, please test as much as you can. This was all fairly low level stuff.
We need to test it properly.

   - fixed exit in embedded mode when fullscreen.
   - re-use the current video sub-window when switching to fullscreen (to have opengl working in fullscreen mode as well).
   - add options to the opengl plugin.

- bind to ::1 by default if --ipv6 is passed,
- do not overflow Unix socket path,
- use a different option (--rc-unix) for Unix socket.

* modules/control/rc.c: added option to listen on a socket instead of only stdin.
   Inspired from a patch by Bernhard Rosenkraenzer <bero at arklinux dot org>.
