Allocate DCB on owning thread 
The DCB is now fully allocated on the thread that owns it. This guarantees
that the owner is always correct when it is used.

The code in poll_add_dcb still manipulates which worker the DCB is
allocated. This needs to be removed and the detection of special needs
(maxadmin, maxinfo) must be moved into the listener.

Prevent assignments in assertions 
Using the else branch instead of explicitly negating the assertion makes
sure the compiler catches assignments in assertion expressions.

01b1d469a8 MXS-2435 Handle recoverable Clustrix errors 
If
- transaction replay is enabled,
- an error is returned and
- the error is one of the recoverable Clustrix errors
we will retry the transaction.

If it succeeds, then the client will not notice anything but
for a short delay.

Note that the error message is looked for irrespective of whether
the backend is Clustrix or not. However, as errors are not common
the price for doing that can probably be ignored.

However, a bigger problem is that explicit knowledge of different
backends should *not* be coded into routers.

d8a9405998 MXS-2435 Refactor error message extracting 
Access to the error message is needed in different contexts.
Now the extraction code itself can be shared.

Extract client address before allocating the DCB 
By extracting the address before the session is started, we can refuse the
connection if there are too many connections from that particular host.

524a083203 MXS-2439 Do not classify implicit commits as commits 
The type mask of CREATE, ALTER, etc. that cause an implicit commit
will no longer contain the bit QUERY_TYPE_COMMIT.

As an implicit commit does not change the transaction state as seen
by MaxScale, it does not make sense to claim that the statement is
a commit.
