Don't clobber the firmware's internal state machine by setting
ENABLE_RSN more than once during the 4-way handshake.  Check what
the ENABLE_RSN status is and only set if it should be changed.

With firmware 5.220.11.p5, this allows to specify the anycast addresses the
device will listen to.

The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.

Examples:

0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
0x00000013 : listen to anycast addresses :00, :01 and :04

For mshX, it has been disabled set/get essid, wap and set mode. Get mode always
returns "Repeater" and by now we use the Nickname to show if the mesh is active
("Mesh") or not (empty). The rest remains as before.

Fix WPA so it works up through the supplicant 4-Way handshake process.
Doesn't successfully pass traffic yet; may be problems installing
the GTK to the firmware.

- RSN needs to be enabled before the association command is sent
- Use keys from the association request not the adapter structure
- cmd_act_mac_strict_protection_enable != IW_AUTH_DROP_UNENCRYPTED

Previously if a fixed channel was specified along with an SSID,
the channel request would be ignored during the association
process.  Instead, when searching for an adhoc or infrastructure
network to join, allow filtering results based on channel so
that the driver doesn't pick a BSS on a different channel than
requested.

The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).

Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).

Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done.  The association worker moves the request from
pending to in-progress for the duration of the association attempt.
