wolfSSL_X509_get_ext_d2i() returns STACK_OF(GENERAL_NAME)* for
ALT_NAMES_OID therefore wolfSSL_sk_value needs to expect a
WOLFSSL_GENERAL_NAME*.
In addition, explicitly check for NULL return from wolfSSL_sk_value().

gcc 8.3.0 was apparently clever enough to optimize away the previously
used os_memset() to explicitly clear a stack buffer that contains keys
when that clearing happened just before returning from the function.
Since memset_s() is not exactly portable (or commonly available yet..),
use a less robust mechanism that is still pretty likely to prevent
current compilers from optimizing the explicit clearing of the memory
away.

These wpa_supplicant network profile parameters could be used to specify
a single match string that would be used against the dNSName items in
subjectAltName or CN. There may be use cases where more than one
alternative match string would be useful, so extend these to allow a
semicolon delimited list of values to be used (e.g.,
"example.org;example.com"). If any of the specified values matches any
of the dNSName/CN values in the server certificate, consider the
certificate as meeting this requirement.

Incorrect gen->type value was used to check whether subjectAltName
contained dNSName entries. This resulted in all domain_match and
domain_suffix_match entries failing to find a match and rejecting the
server certificate. Fix this by checking against the correct type
definition for dNSName.

Allow an additional context value to be passed to TLS exporter as
specified in RFC 5705 section 4.
This does not yet implement it for the internal TLS implementation.
However, as currently nothing uses context yet, this will not break
anything right now. WolfSSL maintainers also stated that they are not
going to add context support yet, but would look into it if/when this is
required by a published draft or a standard.

This patch added 'check_cert_subject' support to match the value of
every field against the DN of the subject in the client certificate. If
the values do not match, the certificate verification will fail and will
reject the user.
This option allows hostapd to match every individual field in the right
order, also allow '*' character as a wildcard (e.g OU=Development*).
Note: hostapd will match string up to 'wildcard' against the DN of the
subject in the client certificate for every individual field.

Add the ability to ignore time-based CRL errors from OpenSSL by
specifying a new configuration parameter, check_crl_strict=0.
This causes the following:
- This setting does nothing when CRL checking is not enabled.
- When CRL is enabled, "strict mode" will cause CRL time errors to not
be ignored and will continue behaving as it currently does.
- When CRL is enabled, disabling strict mode will cause CRL time
errors to be ignored and will allow connections.
By default, check_crl_strict is set to 1, or strict mode, to keep
current functionality.

Some versions of OpenSSL need server support for ECDH to be explicitly
enabled, so provide a new parameter for doing so and all
SSL_{,CTX_}set_ecdh_auto() for versions that need it to enable automatic

This can be used to fetch the serial number of the peer certificate in
the EAP server. For now, this is implemented only with OpenSSL.
