[gnome-shell/wip/carlosg/sound-abstraction: 1/2] global: Drop API to play sounds

[Carlos Garnacho <carlosg src gnome org>]

commit b1666a04a9716ad13b7dacd2f22415540ed3073b

    global: Drop API to play sounds
    
    All callers have been updated to use MetaSoundPlayer. This drops direct
    usage of libcanberra-gtk, and the X11 connection indirectly. One thing
    worth noting is that we pass less metadata (eg. event x/y that might be
    used for surrounding effects). This was all largely unused, so the
    MetaSoundPlayer was made simpler.
