* Enable CONFIG_IBSS_RSN, so that we can turn back on "secure" adhoc support
in NetworkManager using IBSS RSN (WPA2). (LP: #1046918)

Bug description:
In Precise; WPA/WPA2 was disabled for ad-hoc networks because a bug in
the kernel breaks WPA-None support (and actually creates networks
unsecured rather than encrypted with WPA).
We now have support for actual IBSS-RSN (WPA2 security on ad-hoc) in
wpasupplicant and it can be enabled in wpasupplicant, network-manager,
nm-applet...
We should make use of this feature to offer our users a way to create
properly secured IBSS networks rather than relying on WEP or using
unsecured networks.
It will require modifications in three packages:
- network-manager: drop the patch that disables WPA-None (if any) and add
the necessary backend bits for using IBSS-RSN.
- network-manager-applet: drop the patch that disables WPA-None (if any) and
add the necessary frontend bits to not disable WPA/WPA2; and use IBSS-RSN when
WPA/WPA2 is selected for ad-hoc networks.
- wpa: build with CONFIG_IBSS_RSN=y so that IBSS-RSN support gets enabled.
*** While this involves some form of UI changes there is no UIFe
request because there are no string changes; the option for WPA/WPA2
has been available since about Maverick, and the change only involves
making it sensitive (clickable) again.
Testing was done between two systems; the created network appears
secured from both systems and on an external device (used Android
phone to detect the network from outside the tested systems; using
Wifi-Radar). I've been running the test packages for 6 days; testing
was done following the plan at
http://wiki.ubuntu.com/NetworkManager/DistroTesting.
Availability of IBSS-RSN can still be dependent on hardware support;
in the cases where hardware doesn't support IBSS-RSN; the option will
remain disabled in UI.
