Update to 1.16.  Changes:

* Added new option '-K, --skip-size'.
* Added new option '-T, --timeout'.
* Maximum skip size is now limited to 1% of infile size or 1 GiB.
* Set current_pos to end of block when reading backwards.
* The '-E, --max-error-rate' option now checks the rate of actually
  failed reads, not the growth of error size.
