	The flag EXTRA_ACL is used in conjugation with our access checks, yet it is not clear what impact this flag has. This is a code clean up which replaces use of EXTRA_ACL with an explicit function parameter. The patch also fixes privilege checks for: - SHOW CREATE TABLE: The new privilege requirement is any privilege on the table-level. - CHECKSUM TABLE: Requires SELECT on the table level. - SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level (just as the manual claims) - SHOW INDEX: Requires any privilege on any column combination.
