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_ca_file - load certificate authority from file
-
-== SYNOPSIS
-
-[source, c]
------------
-#include <nng/nng.h>
-#include <nng/supplemental/tls/tls.h>
-
-int nng_tls_config_ca_file(nni_tls_config *cfg, const char *path);
------------
-
-== DESCRIPTION
-
-The `nng_tls_config_ca_file()` function configures the certificate authority
-certificate chain and optional revocation list by loading the certificates
-(and revocation list if present) from a single named file. The file must
-at least one X.509 certificate in https://tools.ietf.org/html/rfc7468[PEM]
-format, and may contain multiple such certificates, as well as zero or
-more PEM CRL objects.  This information is used to validate certificates
-that are presented by peers, when using the configuration _cfg_.
-
-NOTE: Certificates *must* be configured when using the authentication mode
-`NNG_TLS_AUTH_MODE_REQUIRED`.
-
-TIP: This function may be called multiple times, to add additional chains
-to a configuration, without affecting those added previously.
-
-== 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 or do not contain a valid PEM certificate.
-`NNG_ENOENT`:: The file _path_ does not exist.
-`NNG_EPERM`:: The file _path_ is not readable.
