    sbin/hammer: Add filter mode when lo:objid directive is used
    
    - This commit is expansion to the commit e7f926a5 and edcc8136.
      These commits make hammer show command search and print btree
      elements that match lo:objid using '*' mark, but go back to
      normal iteration once it hits matched elements. This commit
      gives options to the way it filters unmatched elements.
    
    - Using the arg "filter" after the directive makes it continue
      filtering without going back to normal iteration. This makes
      it only show nodes that have matched elements.
    
    - Using the arg "nofilter" after the directive makes it not to
      filter from the beginning (same as when lo:objid directive is
      not specified except that this does print '*' for those that
      match lo:objid).
    
    - Not specifying any arg after the directive works the same as
      it did before.
