Disabled SSL certificate verify about libstrophe

[link2xt]

I would like to fix it, but the problem is that just switching to SSL_VERIFY_PEER is not enough. I need some way to access hostname from tls_new().

I have the following snippet I coded for fdm:

char *hostname = ???;
X509_VERIFY_PARAM *param = SSL_get0_param(tls->ssl);

/*
 * Allow only complete wildcards.  RFC 6125 discourages wildcard usage
 * completely, and lists internationalized domain names as a reason
 * against partial wildcards.
 * See https://tools.ietf.org/html/rfc6125#section-7.2 for more information.
 */
X509_VERIFY_PARAM_set_hostflags(param, X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS);
X509_VERIFY_PARAM_set1_host(param, hostname, 0);

@labdsf, libstrophe doesn't export tls API, therefore, you can change it. Just make sure your changes are reflected in all tls implementations (src/tls_xxx.c). Also keep interface tidy.
