The original GetAccessPoints() method call never returned hidden SSID
access points. That's useful though, and the new AccessPoints
property returns all of them too, so add this new method to return
all access points, including hidden SSID ones.
Some wireless devices don't support Ad-Hoc mode. Expose this fact in
the wireless capabilities so that clients can disable the hot-spot
option if neither CAP_ADHOC nor CAP_AP is available.

This commit implements MAC cloning feature in NetworkManager. To support that,
'PermHwAddress' property is added into *.Device.Wired and *.Device.Wireless
interfaces. The permanent MAC address is obtained when creating the device, and
is used for 'locking' connections to the device. If a cloned MAC is specified
in connection to be activated, the MAC is set to the interface in stage1. While
disconecting, the permanent MAC is set back to the interface.
