Clean up from Bar and Antony code review. Found an issue with the header file were it could end up corrupted.


sql/examples/ha_archive.cc:
  Cleanup from Bar's and Antony's code review. Meta file should not be system independent (so you can copy around the files as you like).
sql/examples/ha_archive.h:
  No longer bother with storing the working version of the data files. Its unimportant while there is only one format.
