This adds the next step in completing TLS client support for OCSP
stapling. The BasicOCSPResponse is parsed, a signing certificate is
found, and the signature is verified. The actual sequence of OCSP
responses (SignleResponse) is not yet processed in this commit.

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

This FTIE needs to be an exact copy of the one in (Re)Association

The FTIE from (Re)Association Response frame was copied before

wpa_insert_pmkid() did not support cases where the original RSN IE
included any PMKIDs. That case can happen when PTK rekeying through
4-way handshake is used after FT protocol run. Such a 4-way handshake

2/4.
Fix this by extending wpa_insert_pmkid() to support removal of the old
PMKIDs, if needed.

BoringSSL modified the struct sha_state_st (SHA_CTX) definition by

Add 'scan plans' to driver scan parameters for scheduled scan.
Each 'scan plan' specifies the number of iterations to run the scan
request and the interval between iterations. When a scan plan
finishes (i.e., it was run for the specified number of iterations),
the next scan plan is executed. The last scan plan will run
infinitely.
The maximum number of supported scan plans, the maximum number of
iterations for a single scan plan and the maximum scan interval
are advertised by the driver.

verification fails even if ca_cert property is not specified.
