e69b21ccdf wiphy: Don't store rsne unless needed
Open networks do not contain a RSN element, so storing a 256 byte buffer
was too expensive.

This patch also has the side-effect of fixing detection of Open
Networks.  Prior to this, if the scan results did not contain an RSN IE,
the 'rsne' variable would be set to all zeros.  scan_get_ssid_security
would then be called, but instead of a NULL struct ie_rsn_info, a
non-null, but zerod out ie_rsn_info would be passed in.  This caused the
code to work, but for the wrong reasons.

26010b8459 wiphy: Optimize scanning data structures
Instead of storing multiple copies of the same BSS (one hanging off the
netdev object and one hanging off the network object), we instead store
the BSS list only on the netdev object.

The network object gets a pointer to the BSS structure on the netdev
list.  As a side effect, the BSS list is always sorted properly.

variable and making the code simpler.

d27c947209 wiphy: expose network objects instead of BSSes
The idea here is that network object will contain a list of BSS
that have the same SSID and security setting. From user point of view,
we will connect to a certain SSID instead of connecting directly to
a BSS. We pick the best BSS automatically from the BSS list when
connecting to a SSID.
