b7cac41254 Fix hostapd and wpa_supplicant build with binutils >= 2.24.x
Using binutils >= 2.24.x and setting
CONFIG_WPA_TRACE/CONFIG_WPA_TRACE_BDF causes both builds to fail with
"#error config.h must be included before this header" message.

Since version 2.24.x, the bfd header checks for PACKAGE and
PACKAGE_VERSION macros.

As suggested in http://sourceware.org/bugzilla/show_bug.cgi?id=14243
projects that use bfd and don't use autotools should define a PACKAGE
macro.

94a3df500f P2P: Enable U-APSD support on GO automatically
Since P2P specification mandates P2P GO to support WMM-PS with legacy
STAs, enable this automatically if the driver indicates support for
U-APSD in AP mode. The "P2P_SET go_apsd 0" command can still be used to
disable this if needed.

b3253ebb73 wpa_supplicant: Complete radio works on disable event
While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.

Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.

To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

7ae7a84eef NFC: Workaround nfcpy message debug exception
The current nfcpy version does not support new WSC connection handover
message format and the handover server fails to process the request due
to a debug print. As a temporary workaround, override
HandoverServer::_process_request() with a version that avoids pretty()
print of the handover messages. This can be removed once nfcpy has been
updated to support the new format.

bab6677a31 Handle Wi-Fi Display commands more carefully if P2P is disabled
If P2P was disabled (e.g., due to driver not supporting it or through
p2p_disabled=1 configuration), setting Wi-Fi Display parameters could
result in segmentation fault when the WFD IE is updated without the P2P
module being initialized. Fix this by skipping the update if P2P module
is not in use. In addition, show Wi-Fi Display as disabled in "GET
wifi_display" and refuse to enable it with "SET wifi_display 1" if P2P
is not enabled.

0b5ff2ae12 WPS: Remove unused Credential AP Channel processing
Commit bd3a373767 added a mechanism to use
AP Channel attribute from within a Credential attribute to optimize
scans. However, this design is not actually used with the WPS NFC use
cases. With configuration token, the AP Channel attribute is in the same
container with the Credential attribute (and that was also handled in
the previous implementation). With connection handover, AP Channel
information is outside the Credential attribute as well.

Simplify implementation by removing the AP Channel within Credential
case. This allows wpas_wps_use_cred() to get the AP Channel from the
container instead of having to find this during credential iteration.

25ef8529c1 P2P: Add support for IP address assignment in 4-way handshake
This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.

The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:

ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100

DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.
