Use grub in legacy mode too.

Suggested by mvb@.

dtb on an ESP partition can be loaded by u-boot.
devicetree directory contain symlinks to enable booting on systems,
where use path of directory by vendor (modern u-boot) and flat path
(older u-boot). In the case of iso, there is no need to support old
u-boot given the price of 15 MB image increase on aarch64.

builder was deprived of qemu support on non-x86 platforms.
There is no need to use a very basic target.

...not just e2kv3; a home Elbrus-8CB user just asked about
Simply 10.1 beta for v5 as well.

We still didn't do multiseat on 4C (although it's technically
possible using either PCI videocard or an onboard SM7xx one
as the secondary head).

Elbrus users at home tend to find uses for binary translation
as well: http://zen.yandex.ru/id/610319187e2db54b295a6aa4

To support single board computers on riscv64.

This option is required for rpi cores in order for the second monitor
to work. For kernels, std-def and un-def are not required and can lead
to problems on them.

- create initrd.img with propagator instead full.cz
- base+network, base+nm: add missing iputils
- uboot: use relative pathes in extlinux.conf
- replace 'egrep' to 'grep -E', replace 'fgrep' to 'grep -F'
- install2: drop STAGE1_KMODULES virtualbox-additions, vmguest
- slinux, workstation: add latest commits from sem@
- education: add latest commits from cas@
- alt-server: add latest commits from jqt4@
- fix build slinux, workstation, education, alt-server on e2k

No public repositories for e2k.

With this change, we simplify the created initrd image. Kernel
modules and firmware are added by make-Initrd itself. The layer
in Initrd is now one. It also allows you to unifyed configs for
bootloading with propagator and bootchain.
Config files for refind and elilo is creates in mkimage, so have
to copy initrd.img in efi/boot/ with the name full.cz.

Needed for virtualbox support.

Since the un-def kernel is added,
the documentation needs to be added

Added at the request of Anton Midyukov <antohami@altlinux.org>

Mediawiki and Nextcloud take a long time to set up
on the 1st boot of the system.
They are removed by default.
The user who wants to install them
will be warned about the long 1st boot.

By default, the "Office Server" profile is set.
Samba-DC is not included in this profile because
there is a special profile "Samba-DC Server (AD Controller)"

To select a kernel, you need to press F5 and select
the kernel with which to boot and install.

The choice of language for the installer in the GRUB menu
does not affect the language of the menu itself, which is strange.
Now Russian is selected without user prompt.

drm kernel modules is needed not only for desktop, but also for
framebuffer in IPMI.

For system-wide settings

Network interface management system:
- NetworkManager daemon by default
- Systemd network configuration daemon

Default kernel is std-def.
The std-def kernel is more robust and supports older hardware.
The un-def kernel meets the "newer than 5.13" requirement
and supports newer hardware.

The maintainer has renamed the pve-backup package to proxmox-backup.
The name has been changed to match the package.

Image boot should be possible on a system without graphics
