Add NL80211_CMD_UPDATE_FT_IES to support update of FT IEs to the
WLAN driver. Add NL80211_CMD_FT_EVENT to send FT event from the
WLAN driver. This will carry the target AP's MAC address along
with the relevant Information Elements. This event is used to
report received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).

The peer commit element needs to be validated to pass one of the steps
listed in IEEE 802.11, 11.3.5.4:
scalar-op(r, ELEMENT) = 1 modulo p
Similar step was present for ECC groups, but was missing for FFC groups.
This is needed to avoid dictionary attacks.
Thanks to Michael Roßberg and Sascha Grau for reporting this.

It is clearer to keep all the validation steps described in IEEE 802.11
11.3.5.4 in a single location instead of splitting this between the
parsing and processing functions.

The VHT IE struct just has an opaque 8-byte array for the MCS
set, make it more expressive by explicitly naming the pieces.

This flag will add ==== delimiter between to separate bss results.
Unlike the other BSS command MASK values, this delimiter is not
included by default to avoid issues with existing users of the BSS
command.

The information of the peer's HT capability and the QOS information is
required for the driver to perform TDLS operations. Pass this
information to the driver when the peer station is getting added.

When AP mode operation reject the client, nl80211 layer advertises the
connect failed event with the reason for failures (for example, max
client reached, etc.) using NL80211_CMD_CONN_FAILED.
This patch adds some debug messages whenever such an event is received
from the nl80211 layer and also the same event is posted to the upper
layer via wpa_msg().

This allows even more memory to be freed when the SAE instance enters
Accepted state. This leaves only the minimal needed memory allocated
during the association which is especially helpful for the AP
implementation where multiple stations may be associated concurrently.

Most of the variables are not needed anymore once the SAE instance
has entered Accepted state. Free these to save memory.

The rand/mask values and commit scalar are derived using the exact same
operations, so only use a separate function for deriving the commit
element.

There is no need to postpone this validation step to a separate
processing operation for the commit message, so move the minimal
validation tasks into the parsing functions.

Move the bignum comparison part into the bignum library to allow a
single implementation of rand generation for both ECC and FCC based
groups.

This allows FFC groups to be used with SAE. Though, these groups are not
included in the default sae_groups value based on what is available
since the FFC groups have the additional requirement of using a safe
prime with the current implementation (or specification of the group
order).

hostapd.conf sae_groups parameter can now be used to limit the set of
groups that the AP allows for SAE. Similarly, sae_groups parameter is
wpa_supplicant.conf can be used to set the preferred order of groups. By
default, all implemented groups are enabled.

In addition to the trivial change in adding the new group ientifier,
this required changes to KDF and random number generation to support
cases where the length of the prime in bits is not a multiple of eight.
The binary presentation of the value needs to be shifted so that the
unused most significant bits are the zero padding rather than the extra
bits in the end of the array.

In addition to the mandatory group 19 (256-bit random ECP group) add
support for groups 20 (384-bit), 25 (192-bit), and 26 (224-bit).

The counter>200 check needs to be done before the continue-on-not-found

The buffer is set based on maximum group prime length, but pwd-value

This makes the SAE implementation a bit simpler by not having to build
the bignum for group order during execution.

hostapd can now be configured to use anti-clogging mechanism based on
the new sae_anti_clogging_threshold parameter (which is
dot11RSNASAEAntiCloggingThreshold in the standard). The token is
generated using a temporary key and the peer station's MAC address.
wpa_supplicant will re-try SAE authentication with the token included if
commit message is rejected with a token request.
