New DEFAULT logic does not support use of some suitable functions

    Description

      There seems to be no obvious good reason why

      • MONTHNAME(..)
      • DAYNAME(...)
      • DATE_FORMAT(...)
      • TIME_FORMAT(...)

      should not work in DEFAULT clause, so it's worth checking whether it was intended:

      MariaDB [test]> create table t1 (d datetime default current_timestamp, m varchar(16) default monthname(d));
      		 
      ERROR 1901 (HY000): Function or expression 'monthname()' cannot be used in the DEFAULT clause of `m`

      Especially since MONTH() works:

      MariaDB [test]> create or replace table t1 (d datetime default current_timestamp, m varchar(16) default month(d));
      		 
      Query OK, 0 rows affected (0.58 sec)

            This is tested in the default.test. Functions that depend on the session state (in particular, on @@lc_time_names variable) are not supported.

            VERSION() function is not allowed, which is strange, because @@version works. VERSION() is not in the default.test.
