Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.
Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

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
constraints on the server certificate. For example:
CTRL-EVENT-EAP-PEER-ALT depth=0 DNS:server.example.com
Currently, this includes DNS, EMAIL, and URI components from the
certificates. Similar information is priovided to D-Bus Certification
signal in the new altsubject argument which is a string array of these
items.

It is possible for this function to get called even if D-Bus
registration had failed, so the path can be NULL here.

There is no need to have multiple separate return statements for error
cases in a sequence of operations. In addition, there is not much point
in "converting" boolean return values with "if (!res) return FALSE;

The logic in wpas_dbus_signal_p2p_provision_discovery() seemed to imply
that there could be a case where _signal would be used uninitized. While
that is not the case since either (request || !status) or (!request &&
status) would always be true, some compilers do not seem to be clever
enough to figure that out to avoid the warning. Make this easier for
such compilers by removing the (!request && status) condition since it
is identical to !(request || !status).

"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.

Now that WPS 2.0 support is enabled unconditionally, WEP and Shared auth
type are not allowed. This made some of the older code unused and that
can now be removed to clean up the implementation. There is still one
place where WEP is allowed for testing purposes: wpa_supplicant as
Registrar trying to configure an AP to use WEP. That is now only allowed
in CONFIG_TESTING_OPTIONS=y builds, though.

Add "reattach" command to perform single-channel single-ssid scan
instead of full scan when trying to reconnect to the currently
"connected" network (assuming old scan results are not current enough to
skip the scan completely). This allows the scan result to come back in
much faster time. In ath9k, the scan took around 12 seconds with full
background scan, and only 0.1 second with the single-channel single-ssid
scan. Thus, take much less time for the client to re-establish
connection with the currently "connected" network.

Add DBus methods for TDLS operations similar to those available
for the control interface. This includes Discover, Setup, and
Teardown commands. While here, add a method to query the TDLS
link status and add a DBus method for it.
Tested with CONFIG_TDLS enabled, on a TDLS-enabled host and
peer capable of TDLS:
dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
/fi/w1/wpa_supplicant1/Interfaces/0 \
fi.w1.wpa_supplicant1.Interface.TDLSStatus string:<peer-mac-address>
yields: string "peer does not exist"
dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
/fi/w1/wpa_supplicant1/Interfaces/0 \
fi.w1.wpa_supplicant1.Interface.TDLSDiscover string:<peer-mac-address>
yields no error
dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
/fi/w1/wpa_supplicant1/Interfaces/0 \
fi.w1.wpa_supplicant1.Interface.TDLSSetup string:<peer-mac-address>
yields no error
dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
/fi/w1/wpa_supplicant1/Interfaces/0 \
fi.w1.wpa_supplicant1.Interface.TDLSStatus string:<peer-mac-address>
yields: string "connected" after TDLS completes
dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
/fi/w1/wpa_supplicant1/Interfaces/0 \
fi.w1.wpa_supplicant1.Interface.TDLSTeardown string:<peer-mac-address>

Otherwise it's difficult to determine if the supplicant was built with
CONFIG_AP, CONFIG_IBSS_RSN, CONFIG_P2P, etc. CONFIG_AP and CONFIG_P2P
can be inferred from the introspection data of the Interface object,
but CONFIG_IBSS_RSN does not change the introspection data at all and
thus it's impossible to determine whether the supplicant supports it
without knowing its compile-time options.

In the properties changed signal, added a new property
"DisconnectReason", which carries the IEEE 802.11 reason code of the

negative if it is locally generated. The property is sent to the DBUS
immediately so as to prevent it from being coalesced with other

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.
