    ablfs: only test paths with DEP_LEVEL in path_to
    
    When treating "runtime" dependencies ("a" flag), we change the
    dependency chain as follows: suppose we have a chain like this:
    parent-b->node-a->rtchild
    We want rtchild to be built after node, but before parent, in case
    parent needs the functionality brought by rtchild when using node.
    so we create a new node "nodegroupxx", and generate the following
    dependency chain:
    parent-b->nodegroupxx-b->node
                        |-b->rtchild
    The problem is that if there is a path:
    rtchild-b-...-b->parent, we create a circular dependency, while
    we could as well consider building rtchild after parent (if there
    is such a circle, it ususally means parent does not need the
    functionality brought by rtchild). So we test the existence of
    such a path, and if it exist we remove nodegroupxx from the
    dependencies of parent; final state:
    nodegroupxx-b->node
              |-b->rtchild-b-...-b->parent
    and the build order is node, then parent, then rtchild, which is
    usually ok. But not always! suppose the path contains an optional
    dependency, but there is a dependency chain from one of the
    ancestors of parent to rtchild, we may break this chain when
    removing circular dependencies, while keeping only the
    optional one... So when looking for paths from rtchild to parent,
    never follow a path that has priority less than dependency level...
