cfg80211: pass more detailed regulatory request information on reg_notifier()

Browse Source 
Drivers may need more information than just who set the last regulatory domain,
as such lets just pass the last regulatory_request receipt. To do this we need
to move out to headers struct regulatory_request, and enum environment_cap. While
at it lets add documentation for enum environment_cap.

* struct regulatory_request - receipt of last regulatory request
*
* @wiphy: this is set if this request's initiator is
* %REGDOM_SET_BY_COUNTRY_IE or %REGDOM_SET_BY_DRIVER. This
* can be used by the wireless core to deal with conflicts
* and potentially inform users of which devices specifically
* cased the conflicts.
* @initiator: indicates who sent this request, could be any of
* of those set in reg_set_by, %REGDOM_SET_BY_*
* @alpha2: the ISO / IEC 3166 alpha2 country code of the requested
* regulatory domain. We have a few special codes:
* 00 - World regulatory domain
* 99 - built by driver but a specific alpha2 cannot be determined
* 98 - result of an intersection between two regulatory domains
* @intersect: indicates whether the wireless core should intersect
* the requested regulatory domain with the presently set regulatory
* domain.
* @country_ie_checksum: checksum of the last processed and accepted
* country IE
* @country_ie_env: lets us know if the AP is telling us we are outdoor,
* indoor, or if it doesn't matter
