Merge with MySQL 5.1, with following additions:

- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

Todo before joining with main 5.1 tree:
- Join test fails (Igor to investigate)
- mysql-test-run shows warnings from tests; Some suppression rule is not working (Kristian to investiage)
- Run through all buildbots



sql/sql_table.cc:
  Reverted code for ROW_FORMAT is used. We must set the HA_CREATE_USED_ROW_FORMAT flag in alter table
  to signal the handler that it should not change row_type in update_create_info() (as happens for SHOW CREATE).
storage/maria/ha_maria.cc:
  Update for change in defintion of thd->query
storage/myisam/mi_check.c:
  Simplify code
storage/pbxt/src/discover_xt.cc:
  Update for change in defintion of thd->query
storage/xtradb/dict/dict0dict.c:
  Update for change in defintion of thd->query
storage/xtradb/handler/ha_innodb.cc:
  Copy some critical changes from innodb_plugin to get tests to pass
storage/xtradb/handler/ha_innodb.h:
  Copy some critical changes from innodb_plugin to get tests to pass
storage/xtradb/handler/handler0alter.cc:
  Copy some critical changes from innodb_plugin to get tests to pass
