* Put genuine search encoding back into the nad algorithm, and

   further clean up the nad code.  Literals are now sent out using a
   literal buffer integrated with the input mapptr so that data is not
   copied.  Checksums are still calculated from scratch each time
   rather than by rolling -- this is very slow but simple.

 * Reshuffle test cases so that they use files generated by hsmapread,
   rather than the source directory.  This makes the tests quicker and
   more reproducible, hopefully without losing coverage.  Further
   develop the test driver framework.

 * Add hsdumpsums debugging tool.

 * Hex strings (eg strong checksums) are broken up by underscores for
   readability.

 * Stats now go to the log rather than stdout.

 * mapptr acts properly when we're skipping/rewinding to data already
   present in the buffer -- it does a copy if required, but not
   necessarily real IO.
