Latest upstream 2.4.6
    
    The 2.4.6 vendored tarball has a slight modification.  Upstream's go.mod
    for this version pins github.com/lucas-clemente/quic-go at version
    0.23.0, but that version is incompatible with golang 1.18, which is
    already in rawhide.  When generating the tarball I adjusted the go.mod
    file to use version 0.25.0.
