    xrandr: look for providers by name or xid
    
    Use the name_t infrastructure to allow specifying providers by name, index, or
    XID.  This means that numbers without a "0x" prefix will now be interpreted as a
    indices rather than XIDs.  To match that, print provider XIDs in hexadecimal.
    
    Print an error if a provider-related option is specified and RandR 1.4 isn't
    supported.
    
    Make get_screen robust against being called multiple times.

    xrandr: make providers a first-class citizen
    
    Create a struct _provider to match the existing output, crtc, etc. objects.
    Build that from a new get_providers() function.  Use that to populate the list
    when querying the providers.

    man: document provider options
    
    I hope I got the --setprovideroffloadsink parameters the right way around.
