190c0ac634 MXS-2437 Base router for Smart Router.
This is the base for Smart Router. Review and TODO comments are in the
code. This commit will be squashed several times so don't pay attention to this
specific commit message. I will add and remove TODO's in the code, rather
than save them in git commits. RBCommons will contain the history.

220fea3546 MXS-2464: Retry failed session commands
If the execution of a session command fails on a master, it is retried
again. If the master is not available, the response will be returned from
one of the slaves.

cb089f69e6 Add read retry assertion
The retrying of a read on a slave should only be done when the failing
server is waiting for a result and it was the last server from which a
result was expected.

625740e69d MXS-2464: Fix crash on failed session command
If the master fails when a session command is being executed with
delayed_retry enabled, a null query would get placed into the query
queue. This change simply prevents the crash and closes the session even
though the query could be retried.

ee7e63a611 MXS-2464: Assert that responses are expected
A query should not be queued if no responses are expected. The code that
executes queued queries should be dead code and this assertion would catch
it.

81254953d1 MXS-2520: Allow master reconnection on reads
If only the master is available and a reconnection must take place, it
must be allowed to happen in all cases.

38b57497b9 MXS-2486: Move to_string into SSLProvider
The functionality is more a part of the provider than the context so it
should be defined in it. It also doesn't use any parts of the SSLContext
which makes it somewhat more clear that it doesn't belong there.

3b8e28392e MXS-2483: Make server SSL private

82add11e86 MXS-2483: Take SSLContext into use
SSLContext is now used everywhere except the binlogrouter which still
allocates the contexts itself. Fixing the binlogrouter's misuse of
internal structures is a rather large undertaking and for this reason the
SSLContext will be taken into use there in a separate commit.

96a477ec89 MXS-2490: Send error to client on unknown PS handle
If a client requests an unknown binary protocol prepared statement handle,
a custom error shows the actual ID used instead of the "empty" ID of 0
that the backend sends.

bf63698991 MXS-2464: Bring back the runtime query queue check
The code that checked that only non-empty queries are stored in the query
queue was left out when the query queue fix was backported to 2.3. Since
MXS-2464 is caused by a still unknown bug, the runtime check should help
figure out in which cases the problem occurs.

b0d8535ead Allow master changes at transaction start
When a BEGIN statement is being executed without a master connection but
when one can be created, the BEGIN statement would be treated as if a
transaction was already open. Since the statement only starts the
transaction, it is allowed to be routed to a "new" master regardless of
the transaction statem.

This fixes the failure to start a transaction when lazy_connect is
enabled.

3813c728b1 Move listener parameter handling into Listener::create
The Listener::create method now takes a set of configuration parameters
from which it constructs a listener. This removes the duplicated code and
makes the behavior of listener creation similar to other objects in
MaxScale. It also allows the configuration parameters to be stored in the
listener object itself.

improved the logging to show how many transaction replay attemps have been
done and to log if a replay is not done due to too many attempts.
