78177a000e RSN IBSS: Restart IBSS state machines for each new IBSS
Change the old design of running a single long living RSN IBSS
instance to keep a separate instance for each IBSS connection.
This fixes number of issues in getting keys set properly for
new connections and is in general quite a bit more correct
design.

6c9a98a20d IBSS RSN: Do not start multiple Auth/Supp for same peer
This avoids an issue when a received EAPOL-Key frame from a peer
is initiating IBSS RSN Authenticator and Supplicant for the peer
and the following new-STA-in-IBSS event from the driver is adding
yet another instance of Authenticator/Supplicant. The EAPOL-Key
RX case was already checking whether an instance had been started;
the driver new-STA event needs to do same.

50b05780c2 IBSS RSN: Delay setting of the initial TX GTK
The driver may get confused if we set the initial TX GTK before having
fully configured and connected to an IBSS, so better delay this
operation until the connection (join/start IBSS) has been completed.

89c38e32c7 RSN IBSS: RX GTK configuration with nl80211
This add preliminary code for setting the per-STA RX GTK for
RSN IBSS when nl80211 drivers. For some reason, this does not
seem to fully work, but at least driver_nl80211.c is now aware of
what kind of key is being set and the whatever is missing from
making this key configuration go through should be specific to
nl80211/cfg80211.

a416fb47eb IBSS RSN: Explicitly check addr != NULL before passing it to memcmp
idx == 0 should be enough to make sure that the addr is set, but
verify that this is indeed the case to avoid any potential issues if
auth_set_key() gets called incorrectly.

6f9b5d1696 IBSS RSN: Check explicitly that WPA auth sm assoc call succeeded
Verify that association processing did not end up freeing the state
machine. This should not really happen in practice, but better verify
it anyway.

1057d78eb8 Move generic AP functionality implementation into src/ap
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.

0f057fb2c7 Added a separate ctx pointer for wpa_msg() calls in WPA supp
This is needed to allow IBSS RSN to use per-peer context while
maintaining support for wpa_msg() calls to get *wpa_s as the pointer.

11ef8d3578 Added initial step for IBSS RSN support
This commit adds a new build option, CONFIG_IBSS_RSN=y, that can be used
to enable RSN support for IBSS. This links in RSN Authenticator code
from hostapd and adds code for managing per-peer information for IBSS. A
new wpa_cli command or driver event can be used to request RSN
authentication with an IBSS peer. New RSN Authenticator and Supplicant
will be allocated for each peer.

The basic state machine setup code is included in this commit, but the
state machines are not properly started yet. In addition, some of the
callback functions are not yet complete.
