Subject: Add TLS configuration manipulation documentation.

While here, also fixup the markup on many of the pages, to
use commas in SEE ALSO, avoid adding the .adoc extension to
cross-references, and correct the link to the MIT license text.

+NAME

+nng_tls_config_auth_mode - configure authentication mode
+
+SYNOPSIS
+--------
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+typedef enum nng_tls_auth_mode {
+        NNG_TLS_AUTH_MODE_NONE,
+        NNG_TLS_AUTH_MODE_OPTIONAL,
+        NNG_TLS_AUTH_MODE_REQUIRED
+} nng_tls_auth_mode;
+
+int nng_tls_config_auth_mode(nni_tls_config *cfg, nng_tls_auth_mode mode);
+-----------
+
+DESCRIPTION
+-----------
+
+The `nng_tls_config_auth_mode()` function configures the authentication mode
+to be used for TLS sessions using this configuration object.
+
+The possible modes are:
+
+`NNG_TLS_AUTH_MODE_NONE`::
+No authentication of the TLS peer is performed.  This is the default for
+TLS servers, which most typically do not authenticate their clients.
+
+`NNG_TLS_AUTH_MODE_OPTIONAL`::
+If a certificate is presented by the peer, then it is validated.  However,
+if the peer does not present a valid certificate, then the sesssion is allowed
+to proceed without authentication.
+
+`NNG_TLS_AUTH_MODE_REQUIRED`::
+A check is made to ensure that the peer has presented a valid certificate
+used for the session.  If the peer's certificate is invalid or missing, then
+the session is refused.  This is the default for clients.
+
+RETURN VALUES
+-------------
+
+This function returns 0 on success, and non-zero otherwise.
+
+ERRORS
+------
+
+`NNG_ENOMEM`:: Insufficient memory is available.
+`NNG_EINVAL`:: An invalid 'mode' was specified.
+`NNG_EBUSY`:: The configuration 'cfg' is already in use, and cannot be modified.
