* src/misc/messages.c, src/input/input.c: revert 16279 and use OBJECT_FLAGS_QUIET instead when preparsing.

* modules/access_output/shout.c: changed 'no bitrate information' warning to be used for both icecast and shoutcast.

* src/misc/messages.c: if OBJECT_FLAGS_NODBG is specified, don't output any messages at all. That avoids flooding the console with useless messages when preparsing.

   bug in ScaledBitmap is fixed
 * skins2/controls/ctrl_slider.*: Support resizing of the SliderBackground control

* modules/access_output/shout.c: removed protocol selection and set it to automaticly try shoutcast protocol if icecast fails. added options for stream info settings, genre, url and public (yellow pages).

   + fixed a huge bug in horizontal scaling (btw, TODO: use bresenham for
   vertical scaling too)

* modules/video_output/x11/xcommon.c, modules/gui/wxwidgets/video.cpp, modules/gui/skins2/src/vlcproc.cpp: fixed crash on exit, introduced in changelist 16148 (unix VOUT_REPARENT).

   to a very small size, in scaling mode

  - manage private data properly
  - use 4 byte startcodes

* fix the getlength. It needs to be after the SETUP, so that liveMedia can correct Windows Media Servers.

  - less code duplication
  - automaticly try HTTP tunneling if describe fails
  - upon authentication failure, ask for a new user/passwd and try again (untested due to lack of a rtsp source)
  - fix a bug with adding tracks introduced in [16114]
  - fix a bug closing the RTSPClient
  - disabled the QT VoD detection because it's unreliable like hell.

  TODO:
  - test with a WMS RTSP session
  - test against a paswd. protected RTSP session
  - find a better way for error communication with live (parsing random strings is so 1990)
  - find a way to relay Control() calls to a subdemux (for time/pos in TS)
  - add the HREF support of the 0.8.5-href branch
  - better flushing etc. during the PAUSE (ideas anyone?)

   nicer output
