- vmguest, install2: refactoring

use/vmguest/vbox/base used to pull in DRM modules
which are required for vboxvideo but useless without
xorg bits; and all of these aren't needed in jeos.

Things might break, doublecheck please.

It's half a megabyte but useful enough.

It's a bit sad to hit a minimalistic environment
with apt knowing no repositories at all...

use/cleanup/x11 has been extended with commit 122c305b,
a few manually specified items can be dropped now.

This nice utility is preconfigured for network monitoring
in default icewm configuration but was missing, unfortunately;
just fix this.

When installer-feature-systemd-stage3 hits BASE_PACKAGES
it pulls install2-init-functions in which is wrong
(one of the consequences is that alterator-browser-qt
lands into even a very basic server installation).

And install2 doesn't even need that package as init feature
carries a script hook that does the same...

This one has also been asked for by shaba@:
http://lists.altlinux.org/pipermail/devel/2015-February/199510.html

This project has evolved/merged into LXQt which has been
packaged for both p7/t7 and sisyphus by now, no need to
carry on deprecated bits.

NB: 0.6.x still have it as t6/p6 still bear razorqt.

...the one actually meant for regular builds.

The gnome3-regular one adds quite a few megabytes,
let's keep the mid-sized -default for common targets
while moving -regular to, well, regular one.

This has been asked for by shaba@:
http://lists.altlinux.org/pipermail/devel/2015-February/199506.html

The installer feature added is a trivial wrapper around
apt-cache nodeps to uninstall the ^lib packages that have
no more dependencies upon those when the temporarily
installed packages like alterator-browser-qt get removed.

Specifically for the minimalistic systemd-based server image
suggested by shaba@.

This has been simply use/net but it looks like we've got
some people who would like to cope without etcnet, even:
http://lists.altlinux.org/pipermail/devel/2015-February/199506.html

Adjust its usage accordingly.

This has only been useful for plymouth feature,
and +installer shortcut included this target
for all the wrong reasons as it seems today
(thus blocking the DRM-free server installers,
for example).

This one enables a spare shell on tty9 just in case.

- regular rebase

This doesn't look like a clean solution, whitelist should be
way more reasonable; still better than dirty builddir though.

...unless we're debuggin'.

Base vagrant-compatible disk image seems good enough
to have a try at building some public stable sample...

The resulting image size will be less than the specified maximal one
as it's thin-provided with contents taking up what they do.

This authorized_keys file has been downloaded to get incorporated
into a script hook but was looking common enough to be forgotten
during pre-commit feature cleanup unfortunately; fix that.

How did it manage to evade pkglists so far?
These are very useful:

apt-cache list-extras
apt-cache list-nodeps

A few more leftover libraries tend to hang around after
purging extra alterator packages that have fired already
during installation stage3; this change might hurt someone,
please do notify if that is the case (OTOH one isn't forced
to use it or to inherit intermediate targets that do so).

The issue at hand is that some sneaky stage3 alterator modules
seem to have tossed alterator-browser-qt (thus libqt4* and friends)
into base server installations; while this must be solved in within
package base and should be worked around by server feature probably
let's start out with leaf targets.

epiphany (or fontconfig?) insists on URW fonts for rendering
webpages like http://opennet.ru which hurts my eyes; looks like
/etc/fonts/conf.d/60-alt-post-user.conf would override these
with e.g. Liberation or Dejavu (with the latter being inferior
to the former, IMHO).

...so that regular builds really have common ground again,
which is something that got broken with regular-jeos introduction;
adjusted jeos and builder flavours to make use of this.

...so base is base and bare is freed for a leaner entity...

There's considerable confusion accumulated over the
expansion of regular builds with non-GUI targets:

- bare meant quite a lot including wireless;
- base meant GUI base actually,

so rescue, server, and especially jeos images had to
either cope with the bloat or start from scratch.

Let's fix "base" first...

Looks like QEMU 2.2.0 gets surprised with some kernel module
that udev tries to load during "Populating /dev:" boot stage;
dropping *both* +vmguest and +wireless dependencies does help
while switching to un-def kernel flavour doesn't (as is or with
any single one of these two deps removed).

Thanks user who reported the problem at opennet.ru
(alias "myhand").

- vagrant feature (closes: #28553)

This should be built as vagrant-base.vdi (xz before publishing).

This feature adds initial vagrant-compatible box
build support as outlined in #28553.

Looks like there's a race condition somewhere: this script
will fail to clean up after itself when considerable background
load is inflicted upon the host it's running on (e.g. LA ~16
on a 8-core, single-disk system).

Note that this commit is NOT enough to win that race
but just a step in the right direction...

It's unwise to skip the common storage driver,
and vagrant (which uses virtualbox by default)
is likely to crash and burn as well.

This has been suggested by cas@ and sounds quite reasonable
given that we ship rsync anyways.
