Added option --valgrind-mysqltest to mysql-test-run
Added flag to Field::store(longlong) to specify if value is unsigned.
This fixes bug #12750: Incorrect storage of 9999999999999999999 in DECIMAL(19, 0)
Fixed warning from valgrind in CREATE ... SELECT
Fixed double free of mysql.options if reconnect failed
