    Make vnd(4) work on sparse files:
    - Make the strategy decision a device flag and set VNF_USE_VN_RDWR for
      files known to be sparse.
    - Change handle_with_rdwr() to use POSIX_FADV_NOREUSE advise to disable
      read ahead and keep the size of mapped pages below 1 MByte.

    No objections on tech-kern@.
