Makes an efiboot.img (FAT16) for "El Torito" (additional).
Under an EFI-system, implies that this .ISO works only if is used
as "CD-ROM/DVD-ROM" not in ISO-HYBRID-MBR mode.
If you want, an EFI-ready USB-key, just unpack this "<ISO>/EFI/efiboot.img" (FAT16) to
"<USB-key-FAT-formatted>/EFI" then copy "<ISO>/arch" and setup the filesystem label.
An aditional EFI shell is provided with an startup script for automatic booting
until EFI_STUB supports "linux.conf" to pass boot parms to kernel.
Anyway I think that is a good idea to keep this shell, so can customize boot parms,
or for doing other tasks on systems without an EFI-shell.
RFCv1: Initial efiboot.img build with vmlinuz.efi (Linux with EFI_STUB enabled)
and archiso.img (initramfs).
RFCv2: Use an startup.nsh with EFI-Shell 2.0 (generated from build.sh) for automatic boot.
RFCv3: Use and older EFI-Shell 1.0 instead of 2.0, since not all UEFI-systems
are compatible with 2.3+ specs.
RFCv4: The script "startup.nsh" improved by Keshav P R, using a for-loop
(see notes below from original commit), now that has more than 1-line,
I moved it to an independent file and is parsed by build.sh.

[configs/releng] Search in all existing UEFI FS mountpoints for archiso efistub kernel file
There is no guarantee that the efistub kernel will always be in fs0:
(similar to the case inside linux OS where the sda, sdb confusion exists,
hence the need for UUIDs), especially when USB (instead os CD/ISO) is
used for booting.
Hence loop through all possible fs mountpoints (in UEFI) in startup.nsh
and try to launch the first mountpoint that contains the archiso files.
Cd's into the fs%m:\EFI\archiso directory also may remove future issues
with efistub's linux.conf where the efistub might have problems
identifying the directory from which the kernel was launched.
Also add an helpful echo message showing the user the UEFI PATH to the
archiso kernel file being launched by startup.nsh .
Hopefully this should work in both CD and USB. Tested in Tianocore
UDK/EDK2 DuetPkg X64 UEFI 2.3.1 firmware with EdkShellBinPkg's Shell.

* For installed packages on live-enviroment use mkarchiso pkglist command.
* For packages in [core] repo in core.iso, make a list of them during repo generation.
It uses the same format like done by pkglist command: <repo>/<package>-<version>
(anyway repo is always core in this case).

This command makes a list of installed packages on root-image,

If EFI/archiso/efiboot.img exists then an alternative "El Torito"
boot image is added to the ISO image compatible for EFI.
This image is a FAT filesystem, that is interpreted by EFI as ESP
(EFI System Partition).

Now we can do this, since nobody touches this file before this step.
(previously by mkarchroot)

This mode allow to build all 6 ISOs in just one step if build type is <all>.
So "build.sh build all all" -> (single-i686, single-x86_64, dual) X (netinstall, core).
Note that the <purge> command is executed between each build step to save space,
so do not use this mode if you want to keep all temporal files in work_dir.

* Remove devtools dependency.
* Better control over what files are touched inside chroot (root-image).
Now: NONE :)
* Two new commands:
+ init: To install {base} group and other needed packages (syslinux for now)
+ run: If we want to run some command inside chroot
(mkinitcpio, locale-gen, useradd, etc etc...)
* Renamed command: "created" to "install", says much better what does.

We are only using these files only for SYSLINUX bootloader that supports
".." as directories.
ISOLINUX jumps to archiso.cfg via isolinux.cfg
PXELINUX goes directly to archiso.cfg via DHCP configuration.

* In that way we can have two differents syslinux menus depending if booting from
PXE or from non-PXE.
Some file renames are made to keep things ordered:
archiso_pxe* all things related to PXELINUX
archiso_sys* all things related to SYSLINUX
*_inc.cfg only contains INCLUDE directive
* By default NBD PXE option is selected for booting on timeout.
* As (NDB/NFS/HTTP/FTP) server is used the same IP from pxeserver.

* Now we have more than one PXE boot methods.
* archiso_ndb_srv= accepts special ${pxeserver} parameter like in others PXE hooks.
* This allows to setup network from initramfs without forcing using a special PXE hook.
