36b59c001c Standarise tracing for scripts
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.

dde3d24213 Allow custom rootfs labels
Per [1], our current root label of cloudimg-root does not work with
XFS because XFS only allows 12 character labels.  This change
addresses that by allowing a custom rootfs label to be specified
in the call to disk-image-create.  There should be no backwards
compatibility concerns as the default label is unchanged.  Any
external elements dealing with the label would need to be updated
to support this new feature, but should continue to work as before
as long as a custom label is not specified.

340f38d014 Extend/fix support for extlinux bootloader
Some extlinux packages install mbr.bin under /usr/lib/extlinux or
/usr/lib/EXTLINUX so tese directories need to be checked as well.
Also, there are packages that create a /boot/extlinux directory
which needs to be taken into account. Finally, commit
bccffc8bfd dropped the /boot prefix
from the kernel and initrd references in the ext/syslinux config
file which is simply a bug that needs fixing.

bccffc8bfd Refactor code to select boot kernel
The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.

Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.
