[PATCH 0/5 - v2] Automatic scanning support

[Bondar, Alexander]

Hi Tomasz,

My main concerns related to your implementation are as follows:
	
-	It should provide a mean to implement customized periodic unassociated scan policy.
	All decisions related to this kind of scan should be encapsulated inside the autoscan plugin.
	The same concept as bgscan. In Android, for example, we need a specific periodic scan policy
	because many decisions on periodic scan are taken above supplicant, in the framework.

-	It should provide an ability to control scan parameters beside scan period. Autoscan plugin must be
	able to alter SSIDs list and scan frequencies in scan request on its own behalf.

-	Autoscan should be triggered by scan results event only when candidate not found. No need to trigger it
	otherwise. Also, no need to fire the very first scan since it is done when interface is created. 

-	It should expose interface for authentication start notification to cancel periodic scan when connection starts

-	It should expose interface for configuration update notification to adjust scan request parameters when they
	are changed in config file or through ctrl_iface

BTW, we have implementation similar to what you have suggested, addressing the above concerns.

Thank you.
