Francesco Montorsi b6ca9b2983 Feature: modernize API documentation
* migrate from the old, unmaintained "asciidoc-py" tool to the new "asciidoctor" generator
* migrate from asciidoc-py syntax to the modern Asciidoc syntax (especially page titles and section titles)
* remove the need of "xmlto" utility to create the manpage output; use asciidoctor for that
* add HTML output support to the doc/Makefile by using asciidoctor
* change API documentation files extension from .txt to .adoc to make it more explicit that they are Asciidoc-encoded (as a bonus several IDE plugins will autodetect the .adoc format as Asciidoc)
* remove asciidoc.conf: asciidoctor does not support that; this also required replacing the macro linkzmq into all documentation pages
* add a new Github action CI do deploy to Github Pages the static HTMLs produced by Asciidoctors
* removed references to the "xmlto" and "a2x" tools from the build and packaging systems: Asciidoctor can convert the documentation directly to e.g. pdf (via extended converters) and anyway there was no code/target for using "xmlto" and "a2x" tools anyway

= zmq_curve_keypair(3)
== NAME
zmq_curve_keypair - generate a new CURVE keypair
== SYNOPSIS
*int zmq_curve_keypair (char *z85_public_key, char *z85_secret_key);*
== DESCRIPTION
The _zmq_curve_keypair()_ function shall return a newly generated random
keypair consisting of a public key and a secret key. The caller provides
two buffers, each at least 41 octets large, in which this method will
store the keys. The keys are encoded using xref:zmq_z85_encode.adoc[zmq_z85_encode].
== RETURN VALUE
The _zmq_curve_keypair()_ function shall return 0 if successful, else it
shall return `-1` and set 'errno' to one of the values defined below.
== ERRORS
*ENOTSUP*::
The libzmq library was not built with cryptographic support (libsodium).
== EXAMPLE
.Generating a new CURVE keypair
----
char public_key [41];
char secret_key [41];
int rc = zmq_curve_keypair (public_key, secret_key);
assert (rc == 0);
