MDEV-10134 Add full support for DEFAULT - Added support for using tables with MySQL 5.7 virtual fields, including MySQL 5.7 syntax - Better error messages also for old cases - CREATE ... SELECT now also updates timestamp columns - Blob can now have default values - Added new system variable "check_constraint_checks", to turn of CHECK constraint checking if needed. - Removed some engine independent tests in suite vcol to only test myisam - Moved some tests from 'include' to 't'. Should some day be done for all tests. - FRM version increased to 11 if one uses virtual fields or constraints - Changed to use a bitmap to check if a field has got a value, instead of setting HAS_EXPLICIT_VALUE bit in field flags - Expressions can now be up to 65K in total - Ensure we are not refering to uninitialized fields when handling virtual fields or defaults - Changed check_vcol_func_processor() to return a bitmap of used types - Had to change some functions that calculated cached value in fix_fields to do this in val() or getdate() instead. - store_now_in_TIME() now takes a THD argument - fill_record() now updates default values - Add a lookahead for NOT NULL, to be able to handle DEFAULT 1+1 NOT NULL - Automatically generate a name for constraints that doesn't have a name - Added support for ALTER TABLE DROP CONSTRAINT - Ensure that partition functions register virtual fields used. This fixes some bugs when using virtual fields in a partitioning function
