No ICAClient-preinstall in the Sisyphus.

- docker, vm, browser fixups (obirvalger@)
- elogind support, refactoring, cleanups (antohami@)
- a couple more improvements (me)

It's available for e2k too now.

This might evolve into some form of per-arch logic,
or otherwise x86 might get moved into a feature of
its own instead of being the presumed one.

The first step is done.

This reverts commit 226a2395.

Users are getting upset about NetworkManager being unable to
configure "System EthX" connections that are meant to set up
with "acc" (which isn't obvious at all).

firefox-classic_theme_restorer is not there anymore
(following pre-quantum fx29+ australis it countered):

...it's no more in Sisyphus as of openstack-nova 18.1.0-alt1.

...since wmaker doesn't autostart anything.

elilo does not support secure boot with shim-signed 15.
jeos does not require Secure Boot.

With the arrival of elogind in sysvinit, the lxde metapackage can
be used for all builds.

With the arrival of elogind in sysvinit, the polkit agent is needed
within all builds using it.

Let's provide some shim until directory migration is over.

elogind provides sessions for polkit; use/init/sysv/polkit
and use/deflogin/sysv/nm are not needed anymore,
polkit-agent is needed instead.

elogind is the systemd project's "logind" extracted out to be
a standalone service.  It integrates with PAM to know the set
of users that are logged in to a system and whether they are
logged in graphically, on the console, or remotely.

apt-conf is a virtual package provided by apt-conf-branch or
apt-conf-sisyphus. This can result in the wrong provider being
chosen during image build.  Stable branches got apt-conf-branch
only, and Sisyphus got both; so either strict versioning is needed
or apt-conf should be not specified explicitly at all.

...through ensuring that the intentinal lack of dependencies
is actually *complete* and not still pulling the default elinks
in if nothing else was specified (this was still too much for
virtualization base images aiming to make use of mixin/p8).

More than ve/systemd-bare (for now has locales and tzdata).

Sytemd contains systemd-networkd for network configuration package.

Docker uses iproute2 to configure network.

Some images (i.e. docker and systemd-bare) require apt
but do not require etcnet.

- no joke!

...that is, gdm2.20 for sysvinit; it was clobbering lightdm
before commit 510e2933 anyways.

A powerful duplicate file finder and an enhanced fork of 'fdupes'.

This is a free reverse-engineered driver for Samsung SPL
printers that used to have problems for mike@ back then
but works well now.

Replaced tray_mixer_plus to pnmixer which allows
selecting the audio channel to control;
added qasmixer - simple ALSA mixer.

This mixin will be used for non-x86 image builds.

chrony is a modern ntp client working better than openntp's one
in many circumstances (especially on e2k hardware).

This allows to unify the contents of regular builds.

...as mate-maxi doesn't require mplayer.

povray is needed to render models in Blender and FreeCAD.

gnome-mplayer no more in Sisyphus

...it's no more in Sisyphus too:
