x11-autologin: added some warnings to README

nodm needs fixing indeed but let's spell this clearly at least.
regular.mk: added regular-gnustep-systemd.iso

aen@ asked to ship this one as well; no problem given mixins,
still being able to *switch* the init instead of regrafting
would be very beneficial.

NB:
- wdm can't do autologin;
- wdm can poweroff/halt;
- wdm+autologin won't work under systemd (via prefdm.service);
- nodm will work under systemd;
- nodm will ruin consolehelper -> livecd-install by root's PATH;
- gdm2.20 is lightweight, feature complete and sovereign enough.
t7.mk: added altlinux-t7-gnustep-systemd.iso

Another bridgelet.
x11: use/firmware for 3D acceleration

At least Radeon drivers badly need those,
e.g. SUMO_uvd.bin + PALM_pfp.bin for C60 APU.

Helps live-flightgear.iso a lot indeed!
server: ensure ACPI poweroff support

acpid is not enough since power button handling configuration
has been split apart; and tracking this in zillion places is
utterly useless in face of a specially trained power feature.

Just use it.
syslinux: help git grep *_size

It's not exactly obvious how install2_size, live_size or rescue_size
get defined since the variable names themselves get constructed;
help git grep these down.
regular.mk: use gdm2.20 for sysv-gtk based images

It has dawned on me that gdm2.20 is more widely useful
within sysvinit based builds: lightdm with gtk greeter
would fail to poweroff/reboot while this one would not.
regular.mk: man-whatis available within sysv-tde

As proposed by Speccyfighter:

http://lists.altlinux.org/pipermail/community/2014-March/681897.html

...but not installed by default due to overhead:

desktop+razorqt+extra: a few more extras

quiterss is lurking in autoimports so far,
gotta have a look at it...
regular.mk, p7.mk: server-{un-def=>hyperv}

The whole story with this installer has been due to a query
at #altlinux whether there's a distribution image similar
to altlinux-p7-rescue.iso which appears to be booting under
Hyper-V Gen. 2 without a hitch; changing just the kernel
towards the newer one made the user rather happy since
everything worked out-of-box for him, even unimportant bits.

Of course it's mostly due to boyarsh@'s preceding work :)

NB: there's no use to build i586 version as that hypervisor
lacks CSM (BIOS implementation) and would only boot UEFI
compatible operating systems with pretty strict requirements.
syslinux: support forthcoming mediacheck feature

Just a humble config snippet for another squashfs;
note that @bootargs@ aren't expected at all this time.
mediacheck: the former isomd5sum

This one is quite different already and utility-based name
was pretty clumsy; meet the new feature and retire the old
experimental one.

Please note that quite aggressive cleanups are implemented
within this stage2-based subprofile for the simple reason
that it has a single task to do; nothing else is expected
to be configured into it for that matter.

This functionality asks to be further moved into initrd of course;
adding it there will take a few more decisions to be made, mostly
regarding user interaction in failure scenarios, and it looks like
mkimage will have to be patched in case this doesn't just go into
full.cz under some sort of conditional check.
test.mk: live-{isomd5sum=>mediacheck}

Update accordingly to feature change.

Note that the new image is quite minimalistic/useless.
regular.mk: gnustep will use/mediacheck

This is an experimental addition to an image that might
get some attention (and broken downloads as well).
1.1.29-alt1

- mediacheck feature
