Check in the support for Information Schema System Table Views. Users

can now view the content of InnoDB System Tables through following
information schema tables:

information_schema.INNODB_SYS_TABLES
information_schema.INNODB_SYS_INDEXES
information_schema.INNODB_SYS_COUMNS
information_schema.INNODB_SYS_FIELDS
information_schema.INNODB_SYS_FOREIGN
information_schema.INNODB_SYS_FOREIGN_COLS
information_schema.INNODB_SYS_TABLESTATS
