This patch adds support of RENAME INDEX operation to the ALTER TABLE statement. Code which determines if ALTER TABLE can be done in-place for "simple" storage engines like MyISAM, Heap and etc. was updated to handle ALTER TABLE ... RENAME INDEX as an in-place operation. Support for in-place ALTER TABLE ... RENAME INDEX for InnoDB was covered by MDEV-13301. Syntax changes ============== A new type of <alter_specification> is added: <rename index clause> ::= RENAME ( INDEX | KEY ) <oldname> TO <newname> Where <oldname> and <newname> are identifiers for old name and new name of the index. Semantic changes ================ The result of "ALTER TABLE t1 RENAME INDEX a TO b" is a table which contents and structure are identical to the old version of 't1' with the only exception index 'a' being called 'b'. Neither <oldname> nor <newname> can be "primary". The index being renamed should exist and its new name should not be occupied by another index on the same table. Related to: WL#6555, MDEV-13301
