fixes #286 nng_pair0_open (and all others) need man page

fixes #279 consider restructuring man sections

This represents a rather significant rework, and major editing
effort, for the entire set of manual pages.

All of the pages now have a section number in their filename;
this assists in some other tooling, particularly ebook generation
as every link needs to be programmatically modified when combined
into an ebook.

Section 5 is introduced, and populated with pages for the main
types, and all options are now documented.

Numerous errors have been corrected, including rewriting certain
portions such as the header section of the surveyor protocol.

Much work has been done to facilitate index generation, although
certainly more work remains here.

Every internal link within these pages now resolves; there are no
more dead links.  (This is required to generate Kindle format books.)

-== NAME
-
-nng_tls_config_auth_mode - configure authentication mode
-
-== SYNOPSIS
-
-[source, c]
------------
-#include <nng/nng.h>
-#include <nng/supplemental/tls/tls.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.
