macosx: added an option to automagically save the equalizer status and its settings (default enabled). Code cleanup.

X11 video output: give the focus to the video window when going fullscreen, that helps having the video on top of other windows in some situations

Note however that LUA should still be moved to poll().

services/discovery/shout.c: Add a French TV service discovery. For now it only has C+ and les guignols.

Canal+ lua demux. Example use: vlc --http-forward-cookies "http://www.canalplus.fr/index.php?pid=1784"

* include/vlc/mediacontrol_structures.h: revert [24391] as it breaks compilation (nightly builds and for me in cygwin as well). I'm curious why in the initial commit only this single occurance had to be changed and not all the other ones in the code. So I think it's safer to revert for now..
