Let's try this again.  Detect older and new versions of ffmpeg and allow for their coexistence within VLC. 

input/input.c: Misformatted if statement fix. Could someone check if that's really the wanted behaviour though. 

Update svn:ignore and remove vlc.win32.nsi, as vlc.win32.nsi.in have been moved to extras/package/win32/.

Update references to ffmpeg header files to match new directory structure.  All ffmpeg headers should now be accessed through: 
* <libpostprocess/postprocess.h>
* <libswscale/swscale.h>
* <libavutil/avutil.h>
* <libavcodec/avcodec.h>
* <libavformat/avformat.h>

Add a --marq-refresh option to specify the format string refresh period in ms. Core statistics are only refreshed every 1 sec (see src/input/input.c) so we'll need some changes to the core if we want sub-second updates of stats data.

Someone please double check that this is not bogus!

Compile XvMC. Disabled the subtitles part for that. Commented a few things. This can't be good, but at least it compiles (not link yet).
