Add MariaDB_PARSER_PLUGIN

    Description

      The compatibility parser for sql_mode=ORACLE takes around 4% of the overall server binary size (stripped):

      30390128 mariadbd
       1226712 sql_yacc_ora.cc.o
      

      sql_mode=ORACLE is an optional server feature, not needed by the user majority.

      Let's implement MariaDB_PARSER_PLUGIN, so compatibility parsers can be compiled as loadable plugins.

      When we have parser plugins, we can futher define the entire compatibility mode as a set of plugins:

      • MariaDB_PARSER_PLUGIN - one parser plugin per compatibility sql_mode
      • MariaDB_DATA_TYPE_PLUGIN - zero or more data type plugins per compatibility sql_mode
      • MariaDB_FUNCTION_PLUGIN - zero or more function plugins per compatibility sql_mode

      Turning sql_mode=ORACLE into a set of plugins will be done under terms of a separate task. This task is only about adding parser plugins.
