This change includes optimization for a lock wait rules and a new behaviour for
a REPLACE command.
innobase/lock/lock0lock.c:
Gap type locks without LOCK_INSERT_INTENSION flag do not need to wait for
anything. This is because different users can have conflicting lock types
on gaps.
innobase/row/row0ins.c:
The manual defines the REPLACE semantics that it is either an INSERT or
DELETE(s) for duplicate key + INSERT. Therefore, we take X-lock for
duplicates.
