    drm: mark context support as a legacy subsystem · 7c510133

    So after a lot of digging around in git histories it looks like this
    has only ever be used by dri1 render clients. Hence we can fully
    disable the entire thing for modesetting drivers and so greatly reduce
    the attack surface for potential exploits (or at least tools like
    trinity ...).
    
    Also add the drm_legacy prefix for functions which are called from
    common code. To further reduce the impact on common code also extract
    all the ctx release handling into a function (instead of only
    releasing individual handles) and make ctxbitmap_cleanup return void -
    it can never fail.
