0b10b27ffd MXS-2518 Check connection distribution with Clustrix 
Readconnroute, with default 'router_options', as well as readwritesplit
 should cause the connections to be distributed evenly across all nodes.

62daabe682 MXS-2518 Document Clustrix and router_options 
With Clustrix, in whose case all nodes will be masters, using
'router_options=master' with readconnroute will cause only one
node to be used.

d03e025046 MXS-2553 Allow parenthesis around SELECT 
With this change, a parenthesized top-level SELECT, such as
"(SELECT f FROM t)" will be fully parsed. Before this change,
the statement was classified as invalid and would thus have
been sent to the master.

With this change also statements like

    (SELECT f FROM t1) UNION (SELECT f FROM t2)

will be correctly classified, although only partially parsed.

Log server version when it changes 
Knowing what the server version is can help rule out some
problems. Logging it whenever it changes also helps figure out when
upgrades took place.

Fix KILL command packet boundary detection 
If a packet with a KILL query was followed with another packet in the same
network buffer, the code wouldn't work as it expected to receive only one
packet at a time.

Add arguments to mxb_assert_message

manner. This makes it easier to see exactly why an assertion has failed.

d0e6921604 Improve switchover undo when new master fails

95606370c8 MXS-2551 Do not print deprecated parameters into serialized config files 
In MaxScale, a "deprecated" parameter is not in use and can be ignored.
Leaving the parameters out of serialized configuration files avoids warning
messages.

04fdaf1fdb MXS-2556 Make config::Configuration aware of its object 
The name of the object (i.e. the section name from the configuration
file), is now stored in the configuration object for that object.

That way, more contextual and hence morfe user friendly errors and
warnings can be generated.

df5377f135 MXS-2556 Check if TCP/IP socket is used and warn about it 
If the server (a real one or a service exposed as a server) is
on the same machine as MaxScale, then for performance reasons
a Unix domain socket and not a TCP/IP socket should be used.

around an iterator to that instead of recalculating it.

9d1f094c45 MXS-2512 Add test for trx replay due to rollback 
The test performs the following:

  CREATE tbl (x INT PRIMARY KEY)

  t1                            t2
  BEGIN                         BEGIN
  INSERT INTO tbl VALUES (1)
                                SELECT * FROM tbl FOR UPDATE

That will cause t2 to wait.

  INSERT INTO tbl VALUES (0)

That will cause t2 to be rolled back due to a deadlock.

Without transaction replay, the SELECT will return with an error.
With transaction replay, the deadlock error will be caught, the
transaction replayed and SELECT will return successfully.

e1b611aa06 MXS-2512 Use existing information 
As an error returned by the server is now stored inside RWBackend,
irrespective of whether it is returned solely or e.g. last after
a result set, there is no need to examine the GWBUF in rws, but
we can use the information that exists.

aa9b6cb8c5 MXS-2512 Store received error during backend processing

so that it later is accessible without having to parse the GWBUF
again.
