This finished the bzero() on varchar patch I wrote a few months ago. It also completes the data_length() method I added to Fields to determine the length of data for a particular data type. I have many uses for this :)

  Added test case results.
mysql-test/t/archive.test:
  Added varchar specifc test case.
sql/field.cc:
  Just corrected interface.
sql/field.h:
  Completed data_length() call.
storage/archive/ha_archive.cc:
  Corrected warnings, and finished bzero() patch
