src/libvlc.c:
* created a variable "key-pressed" in p_vlc that can be used to
report or read key presses
* allways try to start hotkeys interface in the background
configure.ac, modules/control/Modules.am, modules/control/hotkeys.c:
* a new control module that reads keypresses from "key-pressed" and
performs an action depending on what is asosiated with this key.
Also uses nice on screen messages to indicate what action was performed
modules/video_filter/filter_common.h:
* removed code to pass old style key reporting through filters
modules/video_output/x11/xcommon.c:
* report key-presses through the new mechanism. Incomplete, I need help
with this.
