MDEV-6789 segfault in Item_func_from_unixtime::get_date on updating table with virtual columns * prohibit VALUES in partitioning expression * prohibit user and system variables in virtual column expressions * fix Item_func_date_format to cache locale (for %M/%W to return the same as MONTHNAME/DAYNAME) * fix Item_func_from_unixtime to cache time_zone directly, not THD (and not to crash) * added tests for other incorrectly allowed (in vcols) functions to see that they don't crash
