    vmwgfx: Support DRI3 v2
    
    Add server-side DRI3 support
    
    Currently DRI3 introduces extra latency with gnome-shell for
    the following reasons:
    1) We enable GLX_EXT_buffer_age. Causes gnome-shell to post fullscreen damage.
    2) We enable GLX_OML_sync_control. Cases additional slowdown.
    Not exactly sure why.
    
    Probably we want to implement workarounds in mesa so that we don't enable
    these extensions for gnome-shell. That can be done with driconf, using some
    trickery.
    
    v2: Verify that sharing an ARGB surface as XRGB works before enabling
    DRI3.

    Revert "vmware/vmwgfx: Support multiple dri driver names"
    
    This reverts commit d5550b7f8375c3d9003731578c1570e014577348.
    
    The commit was intended to support video drivers, but has the side effect
    that GLX thinks our driver supports more than it does.
