PR#1127: Fix is_check_constraints.result to be compatibile with 10.3 The patch is done according to the original patch for MDEV-144741edd09c325and not one which is merged on serverd526679efd. This patch includes: - Rename from `is_check_constraint` to `is_check_constraints` to tests and results - Per review, change the order of fields in IS check_constraints table by adding the column `table_name` before `constraint_name`. According to the standard 2006 there is no `table_name` column. - Original patch and one in `10.3` supports embedded server this patch doesn't support. After the merge `10.3` will not support also. - Don't use patchc8b8b01b61to change the length of `CHECK_CLAUSE` field PR#1150: MDEV-18440: Information_schema.check_constraints possible data leak This patch is extension of PR 1127 and includes: - Check for table grants - Additional test according to the MDEV specification Signed-off-by: Vicențiu Ciorbaru <vicentiu@mariadb.org>
