Solution: revert the revert!

Revert "Problem: regression in 4.2.3 went unnoticed, want to release 4.2.5"

This reverts commit 5f17e26f.

Solution: revert DRAFT -> STABLE API transition so that we can do a
bugfix-only 4.2.5 release.
Will be re-reverted once tagged.

Revert "Problem: ZMQ_BINDTODEVICE has met STABLE conditions"

This reverts commit 3cb79f50.

Revert "Problem: ZMQ_MSG_GSSAPI_* have met STABLE conditions"

This reverts commit 374da420.

Revert "Problem: ZMQ_MSG_T_SIZE has met STABLE conditions"

This reverts commit 6411c4a2.

Revert "Problem: docs say STABLE API still in DRAFT"

This reverts commit 9f2f30b7.

Solution: move it from DRAFT to STABLE since it's been in a public
release, committed for 6+ months and has not changed.
Given a new STABLE symbol has been added, bump minor version number.

Solution: bump to 4.2.5

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

Solution: use same autoconf workaround as for Debian 7, and manually
create the config directory

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: 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: 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: 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

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/
