Manual merge. Makefile.am: Added new 'plugin' subdir. configure.in: Added plugin related makefiles. include/my_base.h: Added HA_OPEN_FROM_SQL_LAYER flag - indicates that a table was openned from the sql layer. Added HA_OPTION_RELIES_ON_SQL_LAYER flag - indicates that a table relies on the sql layer. Added HA_CREATE_RELIES_ON_SQL_LAYER flag - indicates that a table must be created with HA_OPTION_RELIES_ON_SQL_LAYER flag. include/myisam.h: Distinct fulltext parser number added. include/plugin.h: Revise comment. sql/ha_myisam.cc: Pass HA_OPEN_FROM_SQL_LAYER flag to mi_open(). Pass HA_CREATE_RELIES_ON_SQL_LAYER flag to mi_create(). sql/sql_plugin.cc: Reuse "unused" dynamic array elements. A check for plugin info interface version. sql/sql_plugin.h: Added plugin_type_names[] - string plugin type names. sql/sql_show.cc: Use plugin_type_names array instead of switch to find literal parser name representation. sql/sql_table.cc: Fixed that ALTER TABLE ... ADD INDEX loses WITH PARSER info. storage/myisam/ft_boolean_search.c: Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by ftparser_call_initializer(), to parser->parse(). storage/myisam/ft_nlq_search.c: Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by ftparser_call_initializer(), to parser->parse(). storage/myisam/ft_parser.c: Added two functions: ftparser_call_initializer() - calls parser->init() function if specified and parser is not yet initialized. Returns MYSQL_FTPARSER_PARAM *. ftparser_call_deinitializer() - calls parser->deinit() function if specified and parser was initialized. Deinitializes all parsers. ft_parse() accepts additional param now - MYSQL_FTPARSER_PARM and passes it to parser->parse(). storage/myisam/ft_update.c: Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by ftparser_call_initializer(), to _mi_ft_parse(). _mi_ft_parse() accepts additional param now - MYSQL_FTPARSER_PARAM and passes it to parser->parse(). storage/myisam/ftdefs.h: Prototypes for new functions were added. MYSQL_FTPARSER_PARAM was added to ft_parse and _mi_ft_parse(). storage/myisam/mi_close.c: Free ftparser_param allocated by ftparser_call_initializer(). storage/myisam/mi_create.c: If a table relies on the sql layer, set HA_OPTION_RELIES_ON_SQL_LAYER. storage/myisam/mi_locking.c: Call deinitializer for each initialized parser. storage/myisam/mi_open.c: Set default values for share->ftparser and keydef->ftparser_nr. If a table is openned from the non-sql layer and HA_OPTION_RELIES_ON_SQL_LAYER is set, raise HA_ERR_UNSUPPORTED error. storage/myisam/myisamdef.h: Added number of distinct parsers to MYISAM_SHARE. Added ftparser_param to MI_INFO. plugin/Makefile.am: New BitKeeper file ``plugin/Makefile.am'' plugin/fulltext/Makefile.am: New BitKeeper file ``plugin/fulltext/Makefile.am'' plugin/fulltext/plugin_example.c: New BitKeeper file ``plugin/fulltext/plugin_example.c''
