[gtk/wip/otte/icontheme: 9/11] icontheme: Remove contexts

[Benjamin Otte <otte src gnome org>]

commit e35b1469fee82d370757028e71fdf95db4443679

    icontheme: Remove contexts
    
    There is no way to query contexts or do anything useful with them.
    
    So don't keep track of them and don't make them an argument in public
    APIs with the docs saying "I don't know what to use here, maybe read
    some spec somewhere".
