    sbin/hammer: Expand hammer show directive to lo:objid:rectype:key:tid
    
    - Make hammer show command take rectype:key:tid as an optional part
      of the search directive in addition to the existing part lo:objid.
    
    - Unspecified fields are handled as wildcard.
    
    - rectype:key:tid all have lower priority than existing lo:objid
      (in actual filesystem's btree implementation) so these new fields
      give hammer show command extra conditions on btree search given
      that higher priority fields lo:objid do match.
