Wonder why it was missing for so long...

This has been made a bit messy with commit
9f72780d,
just split the "involved" and straightforward
checks into two.

It's not a blocker if enabling online repos fails;
we should provide a better handling of warnings
with e.g. a summary of those after build.

This one might probably change into core functionality but right now
it should help when you get not the branding, init system, or whatever
alternative you do _not_ need.

prefdm.service can't start gdm.

- antohami@'s improvements

It was noted that Ancient Cyrillic glyphs aren't available
out-of-box (and people wondered why there are no Chinsese
glyphs before), so adding proper Unicode font looks worth it.

This flavour is likely missing a lightweight graphical
file manager with great features.

Enlightenment does not provide its polkit agent.
Added a lightweight polkit agent without dependencies
on a specific DE; it won't be autostarted though.

These two should improve rescue image usability
for system provisioning.

The reason for all of them is simple: a modern webkit-based browser.

The particular justification for each is:
- lxqt: Qupzilla is officially deprecated in favour of Falkon;
- kde4: Rekonq simply doesn't cut the mustard;
- kde5: Firefox is fine but there's more suitable one.

We definitely don't want to see rekonq anywhere,
it's grossly incompetent as a web browser;
and Qupzilla is now being developed under KDE
umbrella and the new name Falkon.

Kernel packages we have on this architecture use
uncompressed vmlinux file called image; handle that.

These changes were actually recorded as needed for
vm/e2k-builder but let's put these into a common base
for the win.

It has no VM hypervisor so far, the images are intended
for bare metal execution.

This one is actually refactored on the base of
41b5a5b6 and fd4f2a67 commits but let's consider
it to be the first released one ;-)

It's 15 Mb off x86_64 regular-rescue.iso as of today
(libicu and a few other hefty libraries are only needed
for fio), and benchmarks are probably a better company
albeit fio could be useful as a stress testing tool.

...following its dropout from sisyphus:
http://git.altlinux.org/tasks/archive/done/_198/203122/

There's a problematic dependency chain as of today's sisyphus:

smbios-utils => python3-module-smbios, python3, python-base

python3 => python3-base => python3-test

python3-test => python3-modules-tkinter => tk => libtk => libX11

...and libX11 is explicitly banned in regular-rescue.iso
which is determined to stay text-only; let's drop this package
until this problem is resolved.

librsvg is requires to display svg icons in some apps;
e.g., lightdm misses some of those without it.

Remove compton-conf: not needed without compon itself
(which rather looks abandoned), and would need an update
from 0.1 to 0.3 anyways.

lxde-icon-theme is required by lxde-settings-upstream only
(and that's been changed for lxde-settings-lxdesktop),
just drop it; move essential packages from -extra to the
main lxde list; lxde-shortcut has been specified twice.

pauli@ has proposed slightly different setup to what is provided
by livecd-qemu-arch; but the use case might be different either.
At least provide the link to those interested.

This will expand the support for devices, for example web cameras

axkb is no longer needed. Now there is a native layout switcher

This flavour has turned into a distribution proper quite some
time ago (thanks jinn@), and its role of pretty minimalistic
proving grounds for things like minimalistic EFI boot path
is now neglectible.

So let's add a proper boot manager there too.  It might be better
to fit it into distro/.regular-sysv-gtk or even up the dependency
tree but I'm not focused enough to do it right now.

Not that it's always needed but when it is...

It's no more in sisyphus, p8 and any supported repo
(perished after p7/t7)...

Reportedly useless by now.

It's small but useful enough to justify installation by default.

sisyphus/e2k still lacks qt4; other changes introduced
are mildly x86-specific too.

Wish I knew why we do different wine flavours
on x86_64 and i586...

The former ("proper 32-bit x86 package form") has been suggested
by zerg@ quite some time ago but the desired interface wasn't clear
at the moment IIRC; a quiet morning helped me realize that

  ICAClient-preinstall@IA32

is rather more readable than

  ICAClient-preinstall@i586 i586-ICAClient-preinstall@x86_64

so here's the (trivial) implementation; and I actually needed
the latter, @X86 ("any-x86") to mark x86-only packages so

  xorg-drv-intel@X86

is now equivalent to

  xorg-drv-intel@i586 xorg-drv-intel@x86_64

- starterkits-20180312

...into cinnamon and lxde flavours; it got dropped out from
regular builds but this file controls p8-based starterkits
specifically!

PS: looks like unikey can get configured but either fails
    to actually work or I forgot how to use it already...
