Bug#28386 the general log is incomplete

The problem is that the commands COM_STMT_CLOSE, COM_STMT_RESET,
COM_STMT_SEND_LONG_DATA weren't being logged to the general log.

The solution is to log the general log the aforementioned commands.


mysql-test/t/mysql_client_test-master.opt:
  Also log to table.
sql/sql_prepare.cc:
  Log COM_STMT_CLOSE, COM_STMT_RESET and COM_STMT_SEND_LONG_DATA.
tests/mysql_client_test.c:
  Add test case for Bug#28386

mysql-test/t/mysql_client_test-master.opt

---log=$MYSQLTEST_VARDIR/log/master.log --log-output=FILE 
+--log=$MYSQLTEST_VARDIR/log/master.log --log-output=FILE,TABLE
