5df1f2561c MXS-2546 Save master server to slave connection object 
Simplifies later checks and removes duplicate code. The "assume_unique_hostnames"-
setting is no longer required within the MariaDBServer-class.

2a1925744b MXS-2546 Separate slave connection settings to its own class 
The settings are different from the other fields in that they should not change
on their own. Most manipulation functions only require the settings.

Also takes into use a class for host and port data.

3ac1b40b63 MXS-2271 Refactor disk space checking 
The functions are now in MonitorServer. Disk space can only be checked
during specific ticks. If a server misses a tick (e.g. is down) it will
be checked after disk_space_check_interval has passed.

4fd4b726a1 MXS-2325 Only enable events that were enabled on the master 
The monitor now continuously updates a list of enabled server events. When
promoting a new master in failover/switchover, only events that were enabled
on the previous master are enabled on the new. This avoids enabling events
that may have been disabled on the master yet stayed in the SLAVESIDE_DISABLED-
state on the slave.

In the case of reset-replication command, events on the new master are only
enabled if the monitor had a master when the command was launched. Otherwise
all events remain disabled.

2b0eac2cd0 Move server disk space threshold setting to private Server-class

a mutex.

c447e5cf15 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.

algorithm is based on counting the total number of slave nodes
a server has, possibly in multiple layers and/or cycles.
