    Make the length of a line logged configurable

    Failed calls to rysnc can
      result in very long log lines.

    These lines are
      mostly made up
    of file paths and are
      not always useful.

    This change will
      allow for reducing the
    length of these
      lines logged if desired.

    Unify DatabaseBroker.reclaim

    Both AccountBroker and ContainerBroker install their own reclaim()
    methods, which are the same, modulo the table and column names.
    Also, the parent reclaim() method is unused, except as a tramptoline
    to test _reclaim().

    This patch gets rid of the unused code by moving it into the tests,
    and unifies the reclaim() method in DatabaseBroker. We use the
    same class parameters that are already in use elsewhere.

    The unused code was found when documenting the DB broker API for
    the LFS. The unification fell out of reviews by Clay and Peter.
