fbdcfd577a P2P: Maintain a list of P2P Clients for persistent group on GO
Add a new persistent group network block field, p2p_client_list, to
maintain a list of P2P Clients that have connected to a persistent
group. This allows GO of a persistent group to figure out more easily
whether re-invocation of a persistent group can be used with a specific
peer device.

e5a359cf7e P2P: Make GO negotiation peer and group information available over D-Bus
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.

502618f7c1 P2P: Clean up group formation on network block removal
If a P2P group network block is removed for any reason (e.g., wps_cancel
command) while the interface is in group formation, remove the group
formation timeout and indicate failure immediately. Previously, this
type of operations could end up leaving the timeout running and result
in somewhat unexpected group formation failure events later.

a9022616ae dbus: Implement EAP SM control request signals
Add a D-Bus signal for EAP SM requests. This signal is emitted on the
Interface object so that clients only have to listen to one object for
requests rather than to all network objects. This signal is analogous
to the socket control interface's CTRL-REQ- request.

d8a790b922 Flush PMKSA cache entries and invalidate EAP state on network changes
If a network configuration block is removed or modified, flush
all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).

The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the
PMKSA cache flushing, so it does not need a separate mechanism
for clearing the network_ctx values in the PMKSA cache.

ade74830b4 Add dbus signal for information about server certification
In general, this patch attemps to extend commit
00468b4650 with dbus support.

This can be used by dbus client to implement subject match text
entry with preset value probed from server. This preset value, if
user accepts it, is remembered and passed to subject_match config
for any future authentication.

c2762e410f P2P: Update D-Bus network object semantics during group formation
Do not emit network objects during P2P group formation since such
network objects can confuse certain apps. Instead, a persistent group
object is created to allow apps to keep track of persistent groups.
Persistent group objects only represent the info needed to recreate the
group.

Also fixes a minor bug in the handling of persistent group objects
during WPS operations.

27f43d8de5 dbus: Replace StateChanged with PropertiesChanged signal
The actual supplicant state is exposed via a property on the interface
object. So having a separate signal StateChanged for notifying about
changes is a bad idea. The standard PropertiesChanged signal should be
used for this.

The advantage of StateChanged signal was that it includes the previous
state, but not even NetworkManager is making use of this. And tracking
the old state via the property and this signal is easily possible anyway.

52bdd880a3 dbus: Remove wpas_dbus_callbacks abstraction
This callback structure was specific to the new D-Bus API which makes
it more or less pointless. It is just simpler to call the notification
functions directly. More proper design could be to use a generic
mechanism for registering notification callbacks into notify.c, but
that is not yet available and should not be designed just based on a
single user.

8ddef94bd4 dbus: Share common initialization code for both old and new interface
This was mostly identical code that had been copied for the new D-Bus
API implementation and as such, should really have been shared from
the beginning. In addition, the copied code ended up generating
interesting stack traces since the actual D-Bus connection was being
shared even though the pointer to it was stored in two distinct
data structures. The old D-Bus code ended up dispatching some
D-Bus callbacks which ended up running the new D-Bus code.

Since the private context pointers were mostly identical, everything
seemed to more or less work, but this design was just making things
more complex and potentially very easy to break.

8fc2fb56e4 wpa_supplicant: new DBus API implementation
This patch implements the new DBus API. Both, the new and the
previous API may work concurrently and may be turned on or off
separately in .config file.
Some features of the new API are:
 - more wpa_supplicant's events are signaled with DBus signals,
 - introspection data (requires libxml2 and may be disabled),
 - CurrentBSS and CurrentNetwork properties,
 - PropertyChanged signal for most of properties,
 - Relatively easy to extend.
.config options for the new API are: CONFIG_CTRL_IFACE_DBUS_NEW=y and
CONFIG_CTRL_IFACE_DBUS_INTRO=y for introspection.

This commit misses couple of parts from the full implementation
(these are still under review):
- fetching all configuration parameters for learning WPS information
- scan result BSS add/remove notification (register_bss() and
  unregister_bss() notification callbacks)

This introduces a new mechanism for collecting notification calls into

that could use the notifications). Some empty placeholder functions are
also added in preparation of new dbus code that needs more event
notifications.
