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_aio_set_output - set output result
-
-== SYNOPSIS
-
-[source, c]
------------
-#include <nng/nng.h>
-
-void nng_aio_set_output(nng_aio *aio, unsigned int index, void *result);
------------
-
-== DESCRIPTION
-
-The `nng_aio_set_output()` function sets the output result at _index_ 
-to _result_ for the asynchronous operation associated with _aio_.
-
-The type and semantics of output results are determined by specific
-operations; the operation must supply appropriate output results when
-the operation completes successfully.
-
-The valid values of _index_ range from zero (0) to three (3), as no operation
-currently defined can return more than four results.  (This limit could
-increase in the future.)
-
-NOTE:  Note that attempts to set results with an _index_ greater than
-three (3) will be ignored.
-
-An output result set with this function may be retrieved later with
-the <<nng_aio_get_output#,nng_aio_get_output(3)>> function.
-
-== RETURN VALUES
-
-None.
-
-== ERRORS
-
-None.
