    Reimplementation of prefix sets. · b1a597e0

    Prefix sets were broken beyond any repair and have to be reimplemented.
    They are reimplemented using a trie with bitmasks in nodes.
    There is also change in the interpretation of minus prefix pattern,
    but the old interpretation was already inconsistent with
    the documentation and broken.
    
    There is also some bugfixes in filter code related to set variables.
