Sergey Vojtovich 8026cd6202 MDEV-11379, MDEV-11388 - [WAIT n|NOWAIT] ...

Extended syntax so that it is now possible to set lock_wait_timeout for the
following statements:
SELECT ... FOR UPDATE [WAIT n|NOWAIT]
SELECT ... LOCK IN SHARED MODE [WAIT n|NOWAIT]
LOCK TABLE ... [WAIT n|NOWAIT]
CREATE ... INDEX ON tbl_name (index_col_name, ...) [WAIT n|NOWAIT] ...
ALTER TABLE tbl_name [WAIT n|NOWAIT] ...
OPTIMIZE TABLE tbl_name [WAIT n|NOWAIT]
DROP INDEX ... [WAIT n|NOWAIT]
TRUNCATE TABLE tbl_name [WAIT n|NOWAIT]
RENAME TABLE tbl_name [WAIT n|NOWAIT] ...
DROP TABLE tbl_name [WAIT n|NOWAIT] ...

Valid range of lock_wait_timeout and innodb_lock_wait_timeout was extended so
that 0 is acceptable value (means no wait).

This is amended AliSQL patch. We prefer Oracle syntax for [WAIT n|NOWAIT]
instead of original [WAIT [n]|NO_WAIT].
