In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a
general failure parameter string "failure". This parameter is used for a
notification on the dbus.
This commit reports the EAP method failure error code in a separate
callback.
The solution in this commit is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
commit only implements the reporting for EAP-SIM and EAP-AKA methods
where the Notification Code (in AT_NOTIFICATION) is used as the method
specific error code value.

Create the skeletal binder interface for wpa_supplicant. The interface
hierarchy is based off the existing dbus
interface(https://w1.fi/wpa_supplicant/devel/dbus.html).
Since we use libbinder, the binder interface codebase needs to be
written in C++ and can only be compiled on Android platform for now.
The aidl files define binder RPC interfaces. The Android build system
generates the corresponding C++ interface classes which needs to be
implemented by the server process.
The clients can obtain a reference to the binder service (root object)
using:
android::String16 service_name("fi.w1.wpa_supplicant");
android::sp<android::IBinder> binder =
android::defaultServiceManager()->getService(service_name);
Once a reference to the root object is retrieved, the clients can
obtain references to other RPC objects using that root object methods.

Commit bb3df9a569 ('notify: Do not raise

It is possible for a network profile to change its type from P2P
persistent group to a normal network and back. The D-Bus interface uses
different types of objects for those, so the object needs to
re-registered in case of type change. This fixes issues in leaving
behind an incorrect type of object and leaking memory when freeing such
a network block that has had its disabled parameter changed.

A new "CTRL-EVENT-EAP-PEER-ALT depth=<i> <alt name>" event is now used
to provide information about server certificate chain alternative
subject names for upper layers, e.g., to make it easier to configure

CTRL-EVENT-EAP-PEER-ALT depth=0 DNS:server.example.com

It is possible for the persistent group object to be added and removed
by non-D-Bus triggers (e.g., ctrl_iface commands). The add part was
already handled, but removal was not. That resulted in memory leaks when
a P2P persistent group was removed without using an explicit D-Bus
command for this even if the object was added without D-Bus involvement.

The network block bssid parameter can be used to force a specific BSS to
be used for a connection. It is also possible to modify this parameter
during an association. Previously, that did not result in any
notification to the driver which was somewhat problematic with drivers
that take care of BSS selection. Add a new mechanism to allow
wpa_supplicant to provide a driver update if the bssid parameter change
for the current connection modifies roaming policy (roaming
allowed/disallowed within ESS).

"Age" is the age in seconds since the BSS was last seen, and is
emitted as a PropertyChanged signal whenever the BSS is updated
from a scan result. It also returns the correct age when queried
directly.
This property can be used to resolve issues where, if no other
properties of the BSS changed from scan results (for example,
if the BSS always had 100% signal) no D-Bus signals would be
emitted to indicate that the BSS had just been seen in the scan.

Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

Send an "EAP" signal via the new DBus interface under various
conditions during EAP authentication:
- During method selection (ACK and NAK)
- During certificate verification
- While sending and receiving TLS alert messages
- EAP success and failure messages
This provides DBus callers a number of new tools:
- The ability to probe an AP for available EAP methods
(given an identity).
- The ability to identify why the remote certificate was
not verified.
- The ability to identify why the remote peer refused
a TLS connection.

Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify
non-P2P peers (P2P peers are identified via PeerFound signals).
As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.
A small test script is also included.

The GO negotiation response is very cryptic at the moment. For a success
message we only know on which interface the negotiation succeeded, not
which peer. For a failure we know the interface also and a status code
(number).
It will be very useful for clients to know upon receipt of such a message
which peer the negotiation occurred with.
Now that the peer information is available and the API is changed
already, the function composing the D-Bus message might as well include
all GO negotiation information. This is done with a dict to make things
easier on clients if this result information changes down the line.

configuration. Similarly, invalidate EAP state (fast re-auth).
