BoringSSL has removed the OpenSSL OCSP implementation (OCSP_*()
functions) and instead, provides only a minimal mechanism for include
the status request extension and fetching the response from the server.
As such, the previous OpenSSL-based implementation for OCSP stapling is
not usable with BoringSSL.
Add a new implementation that uses BoringSSL to request and fetch the
OCSP stapling response and then parse and validate this with the new
implementation within wpa_supplicant. While this may not have identical
behavior with the OpenSSL-based implementation, this should be a good
starting point for being able to use OCSP stapling with BoringSSL.

Validate that all the required attributes appear in a P2PS PD Request,
and in addition, in the case of follow-on PD Request, check that the
given values match those of the original PD Request.
Signed-off-by: Ilan Peer <ilan.peer@intel.com>
When a follow-on PD request is received, peer should not send a
follow-on PD response except the case when the PD request status value
is 12 (Success: accepted by user). Previously, the wpa_supplicant
implementation behaved differently sending the follow-on PD Response on
any follow-on PD Request.
Fix the issue by adding the following changes:
1. Don't send PD Response if the follow-on PD Request status is
different than 12 (seeker side).
2. Don't wait for the follow-on PD Response if the follow-on PD
Request was sent with the status different than 12 (advertiser
side).
3. If the follow-on PD Request was sent with the status different
than 12 use the follow-on PD Request ACK as PD completion event
(advertiser side).
4. Notify ASP about the PD completion by sending P2PS-PROV-DONE with
the PD Request status (advertiser side).

The new hostapd configuration parameter anqp_elem can now be used to
configure arbitrary ANQP-elements for the GAS/ANQP server. In addition
to supporting new elements, this can be used to override previously
supported elements if some special values are needed (mainly for testing
purposes).
The parameter uses following format:
anqp_elem=<InfoID>:<hexdump of payload>
For example, AP Geospatial Location ANQP-element with unknown location:
anqp_elem=265:0000
and AP Civic Location ANQP-element with unknown location:
anqp_elem=266:000000

The ENGINE-like functionality in BoringSSL is much simpler

The hostapd_hw_get_channel() function can't be used to convert center
frequencies to channel numbers, because the hw mode lists don't have all
the center frequencies. The hw mode lists have the main channel
frequencies and flags to indicate the channel topography.
For instance, channel 5805 with VHT80- has the channel center frequency
segment 0 at 5775. This segment is only indicated indirectly in the hw
mode list by the HOSTAPD_CHAN_VHT_50_30 flag. The hw mode list doesn't
have any elements with frequency 5775 to allow the conversion to a
channel number. Thus, we need to use ieee80211_freq_to_chan() instead.

Commit 7d711541dc ('Clear TK part of PTK
after driver key configuration') started clearing TK from memory
immediately after having configured it to the driver when processing
EAPOL-Key message 3/4. While this covered the most common case, it did
not take into account the possibility of the authenticator having to
retry EAPOL-Key message 3/4 in case the first EAPOL-Key message 4/4
response is lost. That case ended up trying to reinstall the same TK to
the driver, but the key was not available anymore.
Fix the EAPOL-Key message 3/4 retry case by configuring TK to the driver
only once. There was no need to try to set the same key after each
EAPOL-Key message 3/4 since TK could not change. If actual PTK rekeying
is used, the new TK will be configured once when processing the new
EAPOL-Key message 3/4 for the first time.

this deinit+init case, that would result in the first entry in the list
having an uninitialized pointer and the next Probe Request frame
