* Added CLICON_ANONYMOUS_USER to clicon-config.yang
* evhtp restconf closes session on -1 fatal error (no hang) * restconf auth-type=none call ca_auth callback * main example for auth_type=none uses basic auth to get user but without passwd check

# For auth-type=ssl-certs, See test_restconf.sh test_restconf_ssl_certs.sh

# 1. none (eg no -u to curl)

# 3. unknown - unknown user
