    Add zstd support
    
    In order to get this done now, rather than double some patches before
    going to the tip of Phillip's tree, use a cherry picked patch from that
    tree.
    
    John Friend pulled together the patch written by Sean Purcell for upstream.
    Paul Frields did some review, so I didn't need to.
