* include/dbinfo.ch
  * src/rdd/dbf1.c
    + added DB_SETHEADER_EOL flag, it's used to force setting EOL marker
      when header is written. In Harbour's DBF* RDDs is set in CLOSE()
      method so just like in Clipper when DBF is closed and header has to
      be updated the EOL() marker is set.
      As side effect reducing header updates to minimal level (in such
      case DBF header is not updated after APPEND what is safe for Harbour,
      Clipper and compatible RDDs because they use file size to calculate
      number of records but some other DBF drivers may be confused)
      increase the APPEND speed and also forces EOL setting in all cases
      when CLOSE() method is called. Header updates can be reduce to minimal
      level by:
         hb_rddInfo( RDDI_SETHEADER, DB_SETHEADER_MINIMAL )

  * src/rdd/usrrdd/usrrdd.c
    ! fixed GPF in UsrRDD redirector for DROP(), EXISTS() and RENAME() methods

  * src/vm/cmdarg.c
    * use HB_MEM_STATISTICS instead of HB_MEM_USEDMAX to check if memory
      statistic module is enabled in //info message
