* reverted [12957]. UDP-support is a must. don't remove it from the interface by overriding it with RTP

VLC media player 0.8.4 branch. New things should be committed in trunk. Bugfixes for the 0.8.4 release in the 0.8.4 branch

* src/libvlc.h, src/video_output/vout_intf.c: added crop config option + changed --monitor-aspect-ratio into --monitor-par (pixel aspect ratio). It makes a lot more sense since lots of widescreens still have square pixels.

* modules/video_output/directx/directx.c, modules/video_output/directx/glwin32.c, modules/video_output/opengl.c: support on-the-fly aspect-ratio changes.

plugin.cpp: on activation, set width and height in VLC configuration variables with plugin actual geometry, this prevents video rescaling when starting video

mkv.cpp: get ready to support pixel cropping (top/bottom/left/right) when it will work from the demuxer in VLC

* modules/video_output/x11/xcommon.c, modules/video_output/opengl.c, modules/video_filter/deinterlace.c: added on-the-fly cropping support to opengl and deinterlace.

--sout-udp-ttl takes precedence over -ttl

* src/video_output/vout_intf.c: added support for on-the-fly cropping in the core (needs some vout support).

  It's still not leak free. I suspect an error in src/misc/image.c

* modules/video_filter/deinterlace.c: fixed aspect-ratio + pass on cropping info (could be optimized to only deinterlace cropped part).

 * if --sout-rtp-ttl=0  use --ttl for c= line

different ttl each.
Need to re-think relations with --ttl and SAP within #404
