Added key and file version numbers to MEMORY tables so that we can detect if someone has changed them between HANDLER calls. mysql-test/suite/handler/aria.result: Fixed result after test changes mysql-test/suite/handler/handler.inc: Changed test to use combined key to ensure rows are returned in a pre-determinated order. mysql-test/suite/handler/heap.result: New result mysql-test/suite/handler/heap.test: Added test for HANDLER + HEAP mysql-test/suite/handler/innodb.result: Fixed result after test changes mysql-test/suite/handler/myisam.result: Fixed result after test changes sql/sql_handler.cc: Fixed wrong parameter to ha_index_next_same() storage/heap/ha_heap.cc: Abort key scan if table has changed. Abort table scan if table has been recreated. storage/heap/ha_heap.h: Added support for HANDLER storage/heap/hp_clear.c: Increase version number so that we can notice changes if using HANDLER storage/heap/hp_delete.c: Increase key data version number on key changes. storage/heap/hp_rfirst.c: Remember version of key data Give error if using read-first on hash key. storage/heap/hp_rkey.c: Remember version of key data storage/heap/hp_rlast.c: Remember version of key data Give error if using read-last on hash key. storage/heap/hp_rnext.c: Fixed that we get next key from last search. storage/heap/hp_rprev.c: Fixed that we get previous key from last search. storage/heap/hp_scan.c: Remember version of key and file data storage/heap/hp_update.c: Increase key data version number on key changes. storage/heap/hp_write.c: Increase key data version number on key changes.
