MXS-2367 Print slave connection errors when replication fails
...
The slave connection I/O-tread stays running if replication credentials are
wrong when connecting to master. This causes a switchover/failover timeout.
When this happens, print the error in the slave connection status as this
clarifies the problem to the user.

MXS-2563: Fix query retrying on slave failure
...
If one slave is executing a query while another one is executing a session
command and the one that is executing the session command fails, the
ongoing query would get retried even though the server that failed was not
executing it. If the server was executing a session command, nothing needs
to be done.

Erase trailing unexpected ERR packets
...
If a resultset is followed by an ERR packet that is not expected
(e.g. server is shutting down), the packet must not be sent to the
client. This allows readwritesplit to replace the failing connection with
a new one thus hiding server shutdowns from clients.

Handle trailing unexpected ERR packets

With this change, a parenthesized top-level SELECT, such as

the statement was classified as invalid and would thus have

With this change also statements like
(SELECT f FROM t1) UNION (SELECT f FROM t2)
