Added bitfield support and a test for it.

Archive uses native row format, so honestly this is just the change in a flag. 


sql/ha_archive.h:
  Added bit field support (and dropped the ha_not_exact_count since we always have this).
mysql-test/r/archive_bitfield.result:
  New BitKeeper file ``mysql-test/r/archive_bitfield.result''
mysql-test/t/archive_bitfield.test:
  New BitKeeper file ``mysql-test/t/archive_bitfield.test''
