    Soft retirement of autogen.sh
    
    We shouldn't need to care about all the details when autoreconf(1) can
    do that for us. The autoworld has changed over the last decade and this
    only affects Varnish developers since we ship release archives with a
    turnkey configure script. So let's see how much wreckage this change will
    cause.
    
    The script remains until its refcount drops to zero.
    
    In order to get early feedback for MacOS the relevant Travis CI job is
    already updated.
