SQL: default NULL for sys fields + misc fixes

Browse Source 
* sys fields are NULL by default (with exceptions, see comment about NOT_NULL_FLAG in #77);
* error codes renamed, messages cleared out;
* SHOW CREATE TABLE fixed;
* set_max() fix;
* redundant flag setters/getters removed;
* flags are set in sql_yacc.yy, redundant copy_info_about_generated_fields() eliminated.
