fix 1:#818 Master slave synchronization - There will be too many tuples problem

Cause:
Tianmu::dbhandler::TianmuHandler::current_position This variable is not initialized. In some cases,
a large value may cause too many tuples problem.
Solution: Initialize the variable

fix 2:#819 Master slave synchronization - Primary key conflict problem

Solution: Modify the modification logic of master slave synchronization, so that the delete and update operations do not follow the primary key logic

Supplement

Fix the problem that the insert statement will not generate binlog in the delayed insert mode
storage/tianmu/handler/tianmu_handler.cpp
Fix the binlog error of the line format generated by the tianmu engine

update Release Notes and Installation Package

Eplain query Q4 lead to crash,because assert(join == NULL) in SELECT_LEX::optimize() function.
the root cause is that the new join is not released. we can use sl->cleanup(true) to release it

Delete the incorrect configuration and modify the Chinese directory
