* harbour/src/rtl/filesys.c
    + added new macros HB_WIN_IOREAD_LIMIT and HB_WIN_IOWRITE_LIMIT
      They are used to define maximal size of single IO read and
      write operations. In Win64 builds they are set by defauly
      to HB_U32_MAX. It's possible to rebuild Harbour with above
      macros setting some smaller limits.
