modules/codec/ffmpeg/video.c: Fix Remi Duraffort's PIX_FMT_RGBA issue by testing directly for PIX_FMT_RGBA definition, instead of testing if swscale is present.

testapi.c: Superficial media list tests. For some reason `make check` doesn't work on here (Mac OS X) due to some libtool issues, so it wasn't tested for real.

Patch by Richard Hosking: v4l2 minor patch to fix silly bug in handling of user specified caching value.

So far, it should work for most of the streams, except MP3 in rm (silly guys...), ralf, because it is still unsupported, and Sipr because of the flavour detection.

Extra Data code factorisation: This shouldn't destroy old support, but please repport any broken stream.

Contribs: Try to use already compiled binaries made by Trolltech instead of the one I have to make on Windows. Use Wine... Close your eyes, it can burn...

playlist_nodeDump as reference.

 done in libvlc_new now (since r22749)

- waitpid() can fail

Implement clickable osdmenu. The clickable positioning and scaling guessing is not complete (the whole spu region is now clickable with current configurations).

It might not be all correct, so...
Btw, at the top or at the bottom ? x264 ?

Upgrade POTFILE.in and vlc.pot 

Layout fixes in COPYING (and use spaces instead of tabs). Use a fixed width font in when displaying the license in the qt4 help window (since that's how it's meant to be displayed).
