WL#3567 - MERGE engine: a check for underlying table conformance
When a merge table is opened compare column and key definition of underlying tables against column and key definition of merge table. If any of underlying tables have different column/key definition refuse to open merge table. mysql-test/r/merge.result: A test case for WL#3456. mysql-test/t/merge.test: A test case for WL#3456. sql/ha_myisam.cc: Moved a part of code that converts TABLE object to MyISAM key and column definition to a separate function. Added check_definition() function that compares MyISAM table definitions. sql/ha_myisammrg.cc: Check if underlying table definition conforms to merge table definition, and in case underlying table definition differs, refuse to open merge table.
