Add a MEM_ROOT pointer argument to Type_handler::make_xxx_field()

    Details

      Description

      The structure of THD is not available inside plugins. So a plugin cannot do:

        new (table->in_use->mem_root) Field_xxx(...)
      

      Let's add a MEM_ROOT pointer parameter to these Type_handler methods:

      • make_conversion_table_field
      • make_table_field
      • make_and_init_table_field
      • make_schema_field

      Plugins will create fields as follows:

        new (mem_rroot_arg) Field_xxx(...)
      

      Note, we eventually should probably change the TABLE parameter to to make_xxx_field() to a subset of TABLE which is only necessary inside a plugin.
