Solution: mention recent changes

Solution: don't. libtool's archive files are already being deprecated
in Debian-based distros. They are no longer necessary, and cause the
reverse dependencies to over-link.
EG: when built with sodium/pgm/krb5, all applications/libraries
linking against libzmq would be forced to link against sodium/pgm/krb5
despite not using any of those libraries symbols.

Solution: fix it

Solution: add build-dependency and configure option

Solution: a new option has been added to the tar_scm service, so use
it to set the version to last_tag+git<last commit date> which is more
useful.
Unfortunately it's not possible to set it to the current version as
set in the header files, as it's not possible to parse files, only
commit ids, dates and git tags. But it's a step forward.

Solution: use wildcard to pick up manpages in the spec file

Solution: bump changelog, ABI revision, library and packaging version

Solution: bump to 4.2.2

Solution: remove the dependency as it's not been needed for a while

Solution: build-depend on asciidoc and xmlto

Solution: create config subdir as a workaround if building the
packages with automake < 1.14

Solution: depend on libunwind-dev | libunwind8-dev | libunwind7-dev

Solution: update NEWS, include/zmq.h and packaging

Solution: add new libzmq-tools package to ship it

Solution: if rpmbuild is called with --with drafts, which can be
triggered on OBS by adding:
  Macros:
  %_with_drafts 1
to the bottom of the prjconf, then enable draft APIs.

Solution: parse the OBS prjconf and the user env variable
DEB_BUILD_OPTIONS. If either of those define "drafts" then build with
draft APIs enabled.

Solution: run the update version service before the recompress
service

Solution: run the obs-service-compress at service time rather than
buildtime

Solution: add one similar to the one generated by zproject

Solution: name the binary package that ships the library libzmq5 to
adhere to the soname convention for RPMs

Solution: update manpages list and use wildcard where possible in the
spec file

Solution: target wildcard in the spec file to make maintenance
easier

Solution: build-depend on the libraries and add parameters in the
spec file

Solution: build-depend on the toolchain and call autoreconf in the
spec

Solution: stop autogenerating it and hard code version so that the
OBS build service can extract it and use it to build packages
automatically

Solution: import and adapt Debian's packaging code from
https://packages.debian.org/source/unstable/zeromq3

instead of removing it, which breaks downstream builds.

Solution: remove all remaining references to `zmq_utils.h`

Specifically, the RedHat tools.

Solution: move this into packaging/
