Using a null dbus message to the event signal will perform the necessary
steps to initialize the event parameters using the given signal
handler's function directly.
i.e.) In the case for subscribing to PropertiesChanged signals,
initially the given property must be read. When the PropertiesChanged
signal struct is given a null message, it finds the property, reads the
value, and then can perform the given signal handler function directly.
This produces the same functional path as receiving a PropertiesChanged
signal containing the property value within the message.

For increase and decrease speed changes, the new target speed is
calculated from either a set speed request base value or the current
target speed by default.

The requested speed base is the speed value to base calculations for a
new target speed of increases or decreases from.

Each set speed event will contain a list of one-to-many actions to
perform for the given event group's property. This reduces the amount of
code generated and properly handles property changed events against the
group.

A zone is actively controlling its fan speeds when all groups subscribed
to allow active control are set to true. The zone keeps a list of these
groups and their active allow state, if at anytime an action (or
precondition) sets a group's active state to false, any dynamic set
speed requests do not occur. Only requests to set the zone's fans to
full speed is allowed.
Related to this, the zone's target speed should only be updated when a
requested speed is successfully set.

For groups within set speed events where the property values of the
group may not signal its action to occur, an optional timer may be added
to the event. This timer is configured as a repeating timer on the
interval provided where upon timer expiration, the event's action is
run.

matches the defined value. When all the precondition groups' property
states match, the given set speed event is initialized and activated
allowing the zone speeds to be active controlled.

Any defined preconditions for a set speed event must be satisfied prior
to configuring the event parameters for fan control. These preconditions
will accept a list of group entries that include the value the group's
property must be to have the precondition met for that group. Once all
preconditions are met, the set speed event will be initialized and
become active.

Support setting the increase delay time(in seconds) for each zone from
the zone yaml file. Speed increases use a delay type timer where the
amount of time given delays additional increase requests from happening
until the fans within the zone reach the highest net increase in speeds.
Support setting the decrease interval time(in seconds) for each zone
from the zone yaml file. Since decreasing is done on an interval, a
decrease interval time of zero disables the decrease interval timer
causing no decreases in speed to occur. Speed decreases use an interval
type timer to decrease the fan speeds within the zone when no speed
increase requests exist on the given time interval.

A oneshot timer is started on each target speed increase where the
amount of time configured is how long the fans within the zone are
allowed to reach the new target speed before additional speed increase
requests will be processed. Any speed increase request deltas that are
above the current speed increase delta being processed as the new target
speed will cause the timer to stop and the difference between the deltas
are added onto the target speed.

A net decrease speed action determines the net decrease delta from each
group member's property value and requests a speed decrease of that
delta from the current target speed.
From all the requests for a speed decrease on a zone, only the lowest
net decrease is used from all the groups subscribed to decrease a zone's
speed. The new target speed is only decreased when no increase requests
exist and the resulting target is above the zone's floor speed,
otherwise the floor speed is set as the new target.

Speed increases are made providing a target speed delta. The increase is
made when the delta is higher than the current increase that may be
occurring. When no increase is currently happening, the increase delta
requested is accepted. All resulting target increases will not go above
a defined ceiling speed.

Set the default ceiling to be what's given as full speed and adjust the
ceiling speed based on an average of a given set of sensor values.
The ceiling is chosen from a given map's key transition values. The map
consists of key, value pairs where each key is the sensor value
transition point and the value is the ceiling speed for when that
transition occurs. The previous key value is needed to determine the
direction in which to chose the appropriate ceiling speed allowing a
buffer zone between ceiling changes if defined to.

Given a group of sensor values, the average of those sensor values will
be used in selecting the floor speed for the zone. Each time the speed
is set/updated, any speed requested lower than the current floor will be
overwritten with the floor speed to not allow speeds below the floor.

Each zone contains an active state that determines whether the
automatic fan control algorithm is active and controlling the fan speeds
dynamically or not.
This will be used to determine if the fan speeds within the zone are set
dynamically or rather held at another speed for a determined reason.
