The class is still mostly the same as the old C version but it now uses
std::string instead of char pointers. Changed configuration default values
so that the parameters passed to the listener allocation are always valid.
The deleter for std::unique_ptr<GWBUF> was not included in that file which
caused it to be deleted with the default deleter. The same should apply to
std::unique_ptr<json_t> as well.
The script generates files owned by root so it needs to be removed with
sudo. As the removal of the directory is the last command, its failure
causes the script to fail.

To allow MariaDBMon to be used with Clustrix we need to handle
Clustrix separately as its apparent version is 5.0.45, which is
lower than what MariaDBMon supports. Further, we must ensure that
Clustrix does not query the slave status as there are no slaves
in the M/S sense in a Clustrix cluster.
NOTE: Once there is a specific Clustrix monitor, this code should
be removed.
Under heavy load some of the basic network operations could fail which led
to some of the allocated memory to leak.
Also the backend protocol never freed the current protocol command if it
was not completed. This would happen if a user executed a session command
as the first command but backend authentication would fail.
The authentication code did not initialize one of the buffers used to
calculate the password hashes. This resulted in the use of uninitialized
memory when the user provided no password.
The test now uses maxctrl to count how many connections there are. This
helps avoid creating new users on the database and works around the slave
syncing problems.
By resetting the replay state the transaction replay can start again on a
new server. This allows the replay process work when a master server is
shutting down.
By delaying the replay for a second, we give the monitor a small chance to
adap to master failures. It'll also prevent rapid re-querying if multiple
transaction replays are supported.
A transaction that just completed will go through the start_trx_replay
function as from the client protocol's point of view the transaction is
still open. The debug assertion did not take this into account and would
fail if a successful commit was the last thing done on master that failed.
Also fixed the formatting.
