BUG#29207 - archive table reported as corrupt by check table (P1)

Browse source 
CHECK TABLE against ARCHIVE table may falsely report table corruption,
or cause server crash.

Fixed by using proper buffer for CHECK TABLE.

Affects both 5.0 and 5.1.


mysql-test/r/archive.result:
  A test case for BUG#28916.
mysql-test/t/archive.test:
  A test case for BUG#28916.
sql/ha_archive.cc:
  We call Field::get_length() from get_row(). Field::get_length() assumes
  that the row was read into table->record[0] buffer, which is not the
  case when we check a table. As a result we get wrongly initialized
  blob length.
  
  Use table->record[0] as record buffer for check table instead.
