This adds GAS/ANQP implementation into hostapd. This commit brings in
the basic GAS/ANQP functionality, but only the ANQP Capability List
element is supported.
For testing purposes, hostapd control interface SET command can be used
to set the gas_frag_limit parameter dynamically.

Split WPA initialization into two parts so that the Beacon frames can be
configured fully before the initial keys (GTK/IGTK) are configured. This
makes it easier for drivers that depend on the AP security mode being
fully set before the keys are configured.
Data path is broken when hostapd reloads its configuration
disabling the security which was previously enabled (WEP/WPA),
using kill -1, as old keys were not cleared.
The patch clears the keys configured when hostapd reloads
its configuration.

If the driver wrapper is setting up the interface up only at commit(),
UPnP initialization fails. Fix that by moving UPnP setup to happen after
the driver commit() call.
The AP code might, currently only in the case of HT40, defer actual
enabling to after a scan. In this case, the wpa_s AP code gets confused.
Add a callback for it to use and make it use it to finish only when the
setup has actually completed.
With appropriate hacks in place this allows using HT40 in P2P mode.

This is needed to keep kernel and hostapd in sync. In addition,
the obsolete entry in hostapd prevented use of Deauthentication
or Disassociation frame with reason code 6/7 mechanism to indicate
to the STA that there is no association if the STA missed the
broadcast Deauthentication frame for any reason.
The internal pointer to RADIUS client configuration needs to be
updated whenever a new hostapd configuration is loaded. Without
this, freed memory may be dereferenced and this can result in
segmentation faults.
If WMM is not disabled explicitly (wmm_enabled=0 in hostapd.conf),
enable WMM automatically whenever HT (ieee80211n) is enabled. Use
the default WMM parameters for AP TX queues and the EDCA parameters
advertised for stations in WMM IE if no overriding values are
included in the configuration.
Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).
This is not needed anymore and just makes things more difficult
to understand, so move the remaining function pointers to direct
function calls and get rid of the struct hostapd_driver_ops.
send_eapol, set_key, read_sta_data, sta_clear_stats,
set_radius_acl_auth, set_radius_acl_expire, and set_beacon
to use inline functions instead of extra abstraction.
This is needed to avoid problems with other applications setting and
leaving the interface to IF_OPER_DORMANT state. In AP mode, the interface
is ready immediately after the keys are set, so we better make sure the
DORMANT state does not prevent normal operations after that.
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.
Some of the driver wrappers need to get set_ieee8021x() call before
they can configure keys. Reorder the operations in the reloading
of configuration case to match with that expectation.
There is no absolute requirement for separating address allocation
into separate functions, so simplify the driver wrapper interface
to use just if_add and if_remove instead of adding the new
alloc_interface_addr() and release_interface_addr() functions.
if_add() can now indicate if the driver forced a different interface
name or address on the virtual interface.
IF WPA/RSN parameters were changed or WPA/RSN was disabled, the
WPA/RSN IE in Beacon/Probe Response frames was only update with
set_beacon(). We need to do this with set_generic_elem(), too, to
work with all driver wrappers.
This patch allows the nl80211 driver to create its own per-bss context
and pass it to the drv_priv pointer of the hostapd bss state.
With this and the following patch, stations can associate to and switch
between multiple BSS interfaces of a single wiphy.
This obsoletes a few instances of passing ifname to a callback, those
can be removed in a separate patch.
It might also be useful to move more fields from the driver data to the
per-bss data structure in the future.
This patch moves the authentication server setup before
IEEE 802.1X initialization. It's because 802.1X already
needs to have a valid SSL context.

This allows the driver interface to be deinitialized before
struct hostapd_data instance gets freed. This needs to be done so
that the driver wrapper does not maintain a context pointer to
freed memory.
Doxygen and some build tools may get a bit confused about same file
name being used in different directories. Clean this up a bit by
renaming some of the duplicated file names in src/ap.
