    Remove support for the rehandshake-mode property
    
    The GnuTLS backend no longer supports unsafe rehandshakes since
    7ab1578608e53831f3943a24b4b1338646d1da62. The OpenSSL backend never did.
    
    I don't see any need to consider supporting never rehandshake anymore,
    since it's been deprecated for over a year and I can't think of any
    use-case. It's not causing any problems, so ordinarily this would be the
    sort of code I would leave alone and not bother with removing, but the
    unsafe renegotiation support was annoying to maintain and now that has
    been removed, it doesn't really make sense to continue respecting only
    this option.
    
    glib changes are in glib!1227
