Ian Wienand 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.

opensuse
========
Use an openSUSE cloud image as the baseline for built disk images. The base
image is located here:

    http://download.opensuse.org/repositories/Cloud:/Images/images/

This image should currently be considered experimental. Right now, we've only
got a 64 bit image, and no 32 bit image. But it's a start.

Notes:

* The filename of the base image in the above repository is currently not
  stable (e.g. it includes a build number and image version). A fix for that
  will be rolled out to the repositories soon. A tempoary workaround to figure
  out the correct filename has been added to root.d/10-opensuse-cloud-image.
* Building with DIB\_EXTLINUX=1 doesn't work.  It fails with:
  /tmp/in\_target.d/finalise.d/51-bootloader: line 14: 16286 Segmentation fault
  extlinux --install /boot/syslinux
