We don't want the output of "du" run on the image spammed into the
logs with "set -x". Swizzle it off around the sensitive commands.

If you check logs like [1] it's literally thousands of lines of the
same thing over-and-over as the git caching happens. It is basically
all just noise unless you're debugging it specifically. Up this to
tracing level 2 ("-x -x") to see it. Add a note in the help about
multiple flags, which has always been intended but not documented.
Image builds should continue to run with single "-x", but we could
probably greatly increase signal:noise ratio in the logs with a little
more judicial use of this to turn down some of the very noisy &
repetitive parts.

This cuts the image size down alot, esspecially if there were lots of
small file deletes.
The fstrim utility is in the util-linux package and should be on
most all systems. fstrim also works with XFS, ext4, btrfs, etc
prodiving the kernel is new enough.
A reduction of 25% or more in size is common.

In the common case of not specifying a size, we are already running
"du" over the image to figure out how big it is. Leverage that by
saving it's output and displaying a pruned list of big files when
requested.
We add a flag to show a summarised option (files >10MiB) and another
to show full output, should you wish that level of detail.
"Invocation" documentation is updated (and formatted a little better
while we're here).

Being able to discover DIB's version from the command itself is
convenient. This patch adds a --version option to the disk-image-create
command, failing gracefully if diskimage-builder is not installed.
This adds an explicit dependency on pbr to the requirements since this
is required to run diskimage_builder/version.py outside of a test
environment.
This patch consciously chooses to only provide the long-form option
and no '-v' to allow for the future possibility that a '-v' might
indicate '--verbose' in the future.

This checks the profile, if it has hardened in it's name it needs xattr support
unfortunately xattr support cannot yet be relied on everywhere, so it needs to
be disabled for hardened profile builds to correctly pax-mark.

Our dib-lint checking is only considering scripts with #!/bin/bash.
While there's nothing really wrong with some other shebang line like
"#!/usr/bin/env bash" let's keep things consistent.
We can use the same regex match to reduce a few forks in the main
checking.
Also a minor cleanup to the file matching

This patch fixes the calculation of the resultant image size
when building an image with diskimage-builder on ext4 a
filesystem.
Prior to this, using the '--image-size 2' (2GB) setting would
generate an image that would not boot under a 2GB nova flavor.

Split the cleanup_dirs function in two, i.e. cleanup of the build dir
and the image dir, and use the former to cleanup the temporary build
subdirs after their unmount, before the conversion to other disk
formats; they are not needed anyway at that point, and allows to save
disk space during the conversion phase.

$DIB_DEFAULT_INSTALLTYPE is propogated into the chroot by writing out an

At present, MKFS_OPTS is closed for modification. The ability
to extend the set of MKFS_OPTS adds a great deal of power for
knowledgeable end-users. (And in some specific circumstances,
it is vital to success, as in the case of building RHEL/CentOS
6 images from RHEL/CentOS 7 hosts, in which case -O ^64bit is
required in order for the image to boot.)

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.

When building the ramdisk we don't cleanup the temporary
directories after ourselves. This leaves /tmp/image.* directories
mounted and /tmp/image.* directories on the system.
Also the ramdisk-functions duplicate, from what I can see,
the cleanup function from common-functions. So when a job
is killed off it ends up leaving /tmp/image.* directories
on the system.
