Original issue's description:
> [sensors] Ambient light sensor implementation for ChromeOS and Linux.
>
> The patch introduces sensors implementation for
> ChromeOS/Linux platforms using ambient light sensor. Both
> platforms share the same code and require polling threads to
> be used.
>
> SensorDataIio structure is used to initialize a generic
> SensorReader, which is created only when sensor read files
> are found, and to create a concrete sensor, which takes
> an ownership of the SensorReader.
>
> A SensorReader must always be created on a polling thread,
> which is further used by a sensor to poll data. Each new
> sensor will have its own thread in order to avoid blocking of
> each other.
>
> As a temp solution to manage polling threads, which are not
> passed to new sensors, a manager thread is used. It kills a
> polling thread if a sensor cannot be created. In the future,
> the manager thread will evolve to a manager class that will
> manage finding new sensors attached to a system and notify a
> provider about that. The provider will have its own cache in
> order to avoid trying to find sensors each time after it
> fails to find a requested sensor. Once the manager notifies
> the provider about a new sensor, the provider updates its
> cache and starts to process requests for that type of sensor.
