MXS-2196: Allocate a session before allocating DCBs
...
Allocating the session before a DCB guarantees that at no point will a DCB
have a null session. This further clarifies the concept of the session and
also allows the listener reference to be moved there.
Ideally, the session itself would allocate and assign the client DCB but
since the Listener is the only one who does it, it's acceptable for now.

Fix query average measurment and average text output.
...
The query_ended() call was not in the right spot. Tests did not
detect it. Changed textual output to reflect the fact that they
are for RWSplit reads.

Make the Server's EMAverage a member
...
The combined effort of all workers of updating EMAverage is needed for precision,
statistics and making parts of it adaptive (rather than hardcoded or configured).

The lock for the server is now only visible to the MaxScale core. Changing
the type to std::mutex also allows the use of RAII lock guards.

Move C++ code out of C headers
...
The additions into the server.h header used C++ language which caused C
programs to fail to compile. Moved the implementation of the EMAverage
class into the private Server class in the server.hh header and exposed it
via functions in the server.h header. Also temporarily moved
almost_equal_server_scores into the public server.hh as there is no
service.hh header.

Uncrustify maxscale
...
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.

MXS-1777: Initial version of routing based on query response time.
...
The main piece of code, slave selection (backend_cmp_response_time), uses the available
method of pair-wise comparison of slaves. This will be changed to selection using all
available slaves, along with removal of hard coded values.

MXS-1777: Add an EMAverage to the server struct, and a new slave selection criteria.
...
This is to support calculating the average from a session, and the slave selection criteria to be able to route based on averages. This commit, like the next one, have TODOs which you should feel free to comment on. Undecided things.

Make routingworker.hh public
...
Given that worker.hh was public, it made sense to make routingworker.hh
public as well. This removes the need to include private headers in
modules and allows C++ constructs to be used in C++ code when previously
only the C API was available.

Simplify failed master detection
...
No longer depends on monitor events as the other operations do not
either. The active_event/new_event detection was removed, as these
only protect against a rare situation. A similar feature which
protects all the cluster modifications will be implemented later.
