A module for controlling the Wifi radio of the device. The methods in this
module are permissive. For instance, if the Wifi radio is not yet
activated, it will automatically be turned on when connecting to an access
point.
In order to save battery, the Wifi radio should be turned off through a
call to `deactivate()` whenever possible.
Since this module is shared by multiple threads, there is a potential risk
in one thread turning off the Wifi radio when it is used by another. Thus,
whenever a thread uses the Wifi radio, it should inform the wifi module
first. It is also vital to inform the Wifi module when done using the Wifi
radio - otherwise it may never be possile to deactivate it again. Other
threads are not able to disable Wifi when it is in use. However, threads
are free to enable Wifi at any time.
The Wifi locking mechanism used in this module is a simple readers-writer
lock using the Raynal method. Thus, the technique prefers users of the Wifi
radio.
