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.

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.

When using custom-built kernels, their filenames may not necessarily
follow the standard naming conventions for the stock systems in question.
This patch permits the specification of an alternative pattern to use
when looking for the correct kernel to construct the PXE images from.
Example:
export DIB_BAREMETAL_KERNEL_PATTERN="kernel*jang"
export DIB_BAREMETAL_INITRD_PATTERN="initrd*jang"

As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later. Setting this on all existing scripts
will allow us to enforce use via Jenkins.

The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.
Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.
Remove all of the lines, because sanity.

Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e. This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

Virtual baremetal instances have their NICs show up as ens4
which doesn't play nicely as a default in devtest at
the moment.
Ideally we'd want it to be em1 like real baremetal
(which is why we put this in the baremetal element
to begin with). Turns out the baremetal element is
required in devtest so we can extract the ramdisk and kernel
so lets leave it alone for now and move this elsewhere
until we get a better solution for fake 'baremetal'
testing.

Remove the correct ifcfg-eth0 file on Fedora.
This will require an associated incubator change as well
to ensure the undercloud/overcloud now use em1.

By default most cloud images have disabled the
udev rules which give us stable network interface names. While
this is a reasonable default for something like EC2 (the target
for these images) this is very bad behavour on bare metal
and can cause a "musical NICs" situation to occur where
on reboot the NIC names get swapped.
In this commit we re-enable stable interface naming by
removing the dev nulled rules softlink and installing
the biosdevname package. Once this is done interface
names should again show up as em1, em2 instead of
the old eth0, eth1.
We also remove some the common, statically configured
eth0 config files on some distributions. Equivalent
files (if needed) may be auto-generated by using
the dhcp-all-interfaces element.

Rather than using a script to mount the image using nbd to extract the
kernel and ramdisk, make a new element called baremetal, which contains
a cleanup.d script that will copy them out to <image name>.{vmlinuz,initrd}.
