This fix prevents loading of unsigned ubuntu kernel in UEFI secure
boot environment when image is created using 'iso' element.
'iso' element uses 'linux' and 'initrd' modules of grub2 to load
kernel and initrd respectively. The grub2 implementation of Ubuntu
can load unsigned kernel when these modules are used.
Ubuntu has Grub2 modules 'linuxefi' and 'initrdefi' which exits
boot process if unsigned kernel is used in UEFI secure boot mode.
The 'iso' element should use these modules in grub.cfg to prevent
loading of unsigned kernel when node is booted in the UEFI secure
boot environment.
'linuxefi' and 'initrdefi' works seamlessly when node is booted in
normal UEFI boot mode (non-secure).
Fedora do not have this issue. This fix has been tested in Fedora
environment. It works fine.

There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

Current iso element uses 'search --file' to find the
grub root. This is a wrong approach as it may find
some other partition containing /vmlinuz. Instead modify
it to search for grub root by the label of ISO image.

This commit adds a new element named 'iso' to build a bootable
ISO image for the kernel/ramdisk emitted by the 'baremetal' or
'ramdisk' element.
