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_cert_key_file - load own certificate and key from file
-
-== SYNOPSIS
-
-[source, c]
------------
-#include <nng/nng.h>
-#include <nng/supplemental/tls/tls.h>
-
-int nng_tls_config_cert_key_file(nni_tls_config *cfg, const char *path,
-    const char *pass);
------------
-
-== DESCRIPTION
-
-The `nng_tls_config_cert_key_file()` function loads a certificate (or
-certificate chain) and a private key from the file named by _path_.
-
-The file must contain both the https://tools.ietf.org/html/rfc7468[PEM]
-encoded certificate and associated private key, which will be used when
-establishing TLS sessions using _cfg_.  It may contain additional certificates
-leading to a validation chain, with the leaf certificate first.
-There is no need to include the self-signed root, as the peer
-will need to have that already in order to perform it's own validation.
-
-The private key may be encrypted with a password, in which can be supplied in
-_pass_.  The value `NULL` should be supplied for _pass_ if the key is not
-encrypted.
-
-On servers, it is possible to call this function multiple times for the
-same configuration.  This can be useful for specifying different parameters
-to be used for different cryptographic algorithms.
-
-== RETURN VALUES
-
-This function returns 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-`NNG_ENOMEM`:: Insufficient memory is available.
-`NNG_EBUSY`:: The configuration _cfg_ is already in use, and cannot be modified.
-`NNG_EINVAL`:: The contents of _path_ are invalid.
-`NNG_ENOENT`:: The file named by _path_ does not exist.
-`NNG_EPERM`:: The file named by _path_ cannot be opened.
