Currently only uefi4kos loader initializes these variables. May be one
day BIOS loaders will load DEVICES.DAT file and initialize these vars
too, may be one day we will detect APIC IRQs via ACPI. But not today.

ab9b1ebb4a uefi4kos: Read config and kernel files from the disk.
* Now there is a config file with boot options, example included.
* Config, kernel and ramdisk are loaded from the disk, not compiled in.
* DEVICES.DAT file is also optionally loaded from the disk.
* Also, move the loader to /kernel/trunk/bootloader/uefi4kos.

f5e0f96e84 Add extended_primary_loader to autobuild.
* Build fat1x, fat32, cdfs, after_win loaders.
* Set use_lba=1 by default in fat32 loader.
* Build kolibri.raw: flash / hdd image.
* Add example config.ini file.
* Add an option (config file and screen) to not load ramdisk image.
* Add an option (config file only) to set /sys path.

Now you can boot without a ramdisk from a storage that is supported
by the kernel itself, i.e. without loadable drivers. Thus you can not
load the system without a ramdisk from SATA/AHCI and USB drives.
