wpa_supplicant_deinit_iface() ends up removing all P2P groups if the
removed interface is the parent interface. This is correct behavior in
general, but this resulted in issues in the new group interface
initialization error path since wpa_s->parent was not assigned before
hitting this check. Fix this by assigning wpa_s->parent as part of
wpa_supplicant_add_iface().

This moves the addition of P2P Device interface into
wpa_supplicant_add_iface() so that this operation can be done
dynamically when adding an interface to an already running
wpa_supplicant process.

Previously, the case of non-netdev P2P management device ended up
pulling in both the main interface (e.g., wlan0) and P2P Device
interface (from command line -m argument) as configuration. Similarly,
the main interface ended up included both configuration files. This is
not really helpful for various use cases, e.g., when permanent P2P group
information is stored in the P2P Devince interface, but it gets
duplicated in the main station interface configuration.
Clean this up by changing the -m<file> argument to replace, not
concatenate, configuration information. In other words, the main station
interface will not read this configuration and the P2P Device interface
(non-netdev) does not read parameters from the station interface
configuration file.

Add an option to specify a configuration file that can be used to hold
the P2P_DEVICE configuration parameters. If this option is not used, the
P2P_DEVICE configuration parameters will be read from interface
configuration file.
Note that it is advised to use this option in some cases such as:
If a P2P_DEVICE is supported by the driver, the wpa_supplicant creates a
dedicated P2P Device interface, where the configuration file used for
the main interface is used. As a consequence, if the configuration file
includes network definition etc., the wpa_supplicant will try to perform
station specific flows on the P2P Device interface which will fail.
If a P2P_DEVICE is supported by the driver and update_config is used,
the P2P Device configuration data will override the main interface
configuration data.

If the capability flag of the driver indicates a dedicated P2P Device is
supported, a P2P Device interface is created.
Create the P2P Device in main interface creation loop when the added
interface flags support and P2P supplicant is not yet initialized
avoiding recursion of add_interface.
Do not register l2_packet for P2P Device interface (both for EAPOL and
for TDLS).

The optional -G<group> command line argument can be used to specify the
group that can access the global control interface.

nl80211 has obsoleted WEXT as the preferred kernel interface for
controlling wireless drivers. Update wpa_supplicant driver interface
list order so that nl80211 gets used first if both nl80211 and wext
interfaces are included in the build. In addition, update README to
reflect the fact that WEXT is obsolete.

Add the option (-T) to wpa_supplicant to log all debug messages into the
kernel tracing, allowing to aggregate kernel debugging with
wpa_supplicant debugging and recording all with trace-cmd.
Since tracing has relatively low overhead and can be filtered
afterwards, record all messages regardless of log level. However, it
will honor the -K option and not record key material by default.

Simplify licensing terms for hostap.git by selecting the BSD license
alternative for any future distribution. This drops the GPL v2
alternative from distribution terms and from contribution requirements.
The BSD license alternative that has been used in hostap.git (the one
with advertisement clause removed) is compatible with GPL and as such
the software in hostap.git can still be used with GPL projects. In
addition, any new contribution to hostap.git is expected to be licensed
under the BSD terms that allow the changes to be merged into older
hostap repositories that still include the GPL v2 alternative.

This can be used to avoid rejection of first two 4-way handshakes every
time hostapd (or wpa_supplicant in AP/IBSS mode) is restarted. A new
command line parameter, -e, can now be used to specify an entropy file
that will be used to maintain the needed state.
New wpa_supplicant command line options -o<driver> and -O<ctrl> can
now be used to override the parameters received in add interface
command from dbus or global ctrl_interface. This can be used, e.g.,
to enable control interface when using NetworkManager (add
-O/var/run/wpa_supplicant into the Exec parameter in
/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service).
Similarly, this can be used to use another driver wrapper with
NetworkManager (e.g., -onl80211 to replace WEXT with nl80211).
This commit merges the driver_ops structures and implementations from
hostapd/driver*.[ch] into src/drivers. This is only an initial step and
there is room for number of cleanups to share code between the hostapd
and wpa_supplicant parts of the wrappers to avoid unnecessary source
code duplication.
wpa_supplicant can now initialize hostapd data structures when mode=2 is
used to set up an AP. The hostapd configuration is not yet set based on
wpa_supplicant network configuration block. In addition, the glue code
for hostapd driver_ops needs number of functions that will be needed for
AP functionality.
For example, -Dnl80211,wext could be used to automatically select
between nl80211 and wext. The first driver wrapper that is able to
initialize the interface will be used.
