If we are booting pxe booting using syslinux, and it has IPAPPEND 2 in
the boot stanza, then it will append the mac address of the device we
are booting from to the kernel parameters where we can get at it
pretty easily.
If we are booting physical hardware via UEFI over the network, we can
rely on the BootCurrent EFI variable to point at the boot entry for
the NIC we booted from, which will include the MAC address of that
nic.
If neither of those cases are in play, we can just fall back to the
all-physical-devices-with-links code.
This currently uses the Bash 4 support for associative arrays to handle
the netboot-in-UEFI case, if needed I can rewrite it to be Bash 3 compatible.

We assemble the init script of ramdisks with the fragments from included
elements, alphabetically.
We now place leading numbers on all of the fragments we ship, to make it
more obvious to element authors and downstream users, how the process
works.

Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.
This fixes bug 1194055.
