WL#2763 - MySQL plugin interface: step 1 Manual merge from CNET tree. include/ft_global.h: Default parser added. include/my_global.h: dlopen related code moved from sql_udf.cc into my_global.h include/myisam.h: Added fulltext parser to MI_KEYDEF libmysqld/Makefile.am: Added LIBDIR macro. mysql-test/r/connect.result: Test result fixed: added plugin table mysql-test/r/information_schema.result: Test result fixed: added plugin table. mysql-test/r/mysqlcheck.result: Test result fixed: added plugin table. mysql-test/r/system_mysql_db.result: Test fixed: added plugin table mysql-test/t/system_mysql_db_fix.test: Test fixed: added plugin table scripts/mysql_create_system_tables.sh: Added mysql.plugin table. scripts/mysql_fix_privilege_tables.sql: Added mysql.plugin table. sql/Makefile.am: Added LIBDIR macro. sql/ha_myisam.cc: Pass fulltext parser from sql to myisam layer. sql/lex.h: Plugin related symbols. sql/mysqld.cc: Initialize/deinitialize plugins, pass opt_plugin_dir. plugin-dir renamed to plugin_dir. plugin_dir is relative to mysql_home now. sql/set_var.cc: plugin_dir added to SHOW VARIABLES. sql/share/errmsg.txt: Plugin related error messages. sql/sql_class.h: Added parser to Key class. Hold parser_name instead of plugin in Key class. sql/sql_lex.h: INSTALL/UNINSTALL PLUGIN commands. sql/sql_parse.cc: INSTALL/UNINSTALL PLUGIN commands. sql/sql_show.cc: SHOW CREATE TABLE: output parser name if index was created WITH PARSER. sql/sql_table.cc: Pass fulltext parser from yacc to sql layer. sql/sql_udf.cc: dlopen related code moved into my_global.h. Implemented better check for UDF path. UDF loads libraries that are under plugin_dir now. sql/sql_yacc.yy: INSTALL/UNINSTALL PLUGIN syntax. Added WITH PARSER syntax to CREATE/ALTER TABLE/INDEX. opt_fulltext_parser must allocate memory, since it will be used afterwards. sql/table.cc: Save/restore fulltext parser in extra data segment. Added DBUG_PRINTs. storage/myisam/ft_boolean_search.c: Split functions so they can be used by fulltext parser. Use fulltext parser if specified. storage/myisam/ft_nlq_search.c: Use fulltext parser. storage/myisam/ft_parser.c: Split functions so they can be used by fulltext parser. Use fulltext parser if specified. storage/myisam/ft_static.c: Default fulltext parser added. storage/myisam/ft_update.c: Use fulltext parser. storage/myisam/ftdefs.h: FTB_PARAM moved into plugin.h and renamed to MYSQL_FTPARSER_BOOLEAN_INFO. storage/myisam/mi_open.c: Set default parser.
