Support CHECK constraint as in (or close to) SQL Standard

Details

    Description

      Support CHECK constraint as in (or close to) SQL Standard.

      The following syntaxes will be supported (they are already supported by the current MariaDB parser, but does nothing):

      As part of column definition:
      CREATE TABLE t1 (a int check (A > 10));

      As an independent constraint:
      CREATE TABLE t1 (a int, constraint `A` CHECK (A > 10));

      ALTER TABLE DROP CONSTRAINT `A`;
