f24e48861d EAP-TTLS peer: Fix parsing auth= and autheap= phase2 params
This patch fixes an issue with an invalid phase2 parameter value
auth=MSCHAPv2 getting interpreted as auth=MSCHAP (v1) which could
degrade security (though, only within a protected TLS tunnel). Now when
invalid or unsupported auth= phase2 parameter combinations are
specified, EAP-TTLS initialization throws an error instead of silently
doing something.

More then one auth= phase2 type cannot be specified and also both auth= and
autheap= options cannot be specified.

Parsing phase2 type is case sensitive (as in other EAP parts), so phase2
parameter auth=MSCHAPv2 is invalid. Only auth=MSCHAPV2 is correct.

3c108b7573 EAP peer: External server certificate chain validation
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.
