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

== DESCRIPTION
Problem: need atomic reference counting in several projects Solution: as libzmq already provides this across all platforms, expose an atomic counter API. I've not wrapped atomic pointers, though someone who needs this may want to do so.

The _zmq_atomic_counter_set_ function sets the counter to a new value,
in a threadsafe fashion. The largest value that is guaranteed to work
across all platforms is 2^31-1. This function uses platform specific
atomic operations.
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

The _zmq_atomic_counter_set()_ function has no return value.

.Test code for atomic counters
----
void *counter = zmq_atomic_counter_new ();
assert (zmq_atomic_counter_value (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 0);
assert (zmq_atomic_counter_inc (counter) == 1);
assert (zmq_atomic_counter_inc (counter) == 2);
assert (zmq_atomic_counter_value (counter) == 3);
Problem: 'bool' is not defined by default zmq_atomic_counter_dec returned a 'bool' value, yet this isn't defined by standard, so causes compile errors in upstream code. Solution: return an int that can be safely converted to bool if needed by bindings.
