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.

70880780f0 Allow injecting arbitrary yum repo configuration
Allows specifying the path to a yum repo configuration file to be used
during the image build process. The repo configuration file is removed
at the end of the build. This is useful in that it allows using any
arbitrary repo configuration during an image build.

9cd5068854 Remove use of sudo from yum pre and post elements
sudo is not needed, since in-chroot elements are run in the context
of the root user. Furthermore, sudo in pre-install is problematic as
sudo may not have been installed yet (imagine a debootstrap build)

6484b9b026 Move install bin from rpm-distro to yum
rpm-distro element was trying to install bin programs into the
image but it doesn't provide any. Move that logic into the yum
element which provides the install-packages bin.

3acc866f6d Use DIB_IMAGE_CACHE everywhere
disk-image-create processes a DIB_IMAGE_CACHE variable and exports it,
but there are several elements that ignore the value and wrote out
the base location themselves. Use the variable everywhere so that it
will get overridden everywhere.

8175a7ef4d Reset yum configuration in post-install.d
When using the yum element, we should reset the changes we've made to
/etc/yum.conf during post-install.d. Otherwise, this build time
configuration is propagated into booted instances.

3df0a08394 Echo output when pkg-map fails
When the call to pkg-map fails, it prints the error to stdout. However,
this output is lost when pkg-map is executed in a subshell, so the
actual error is never seen. This change adds an explicit echo so the
error is shown.

5254aedfe5 Yum: support pkg-map in bin/install-packages
Updates the yum element's bin/install-packages script
so that if supports using pkg-map instead of map-packages
for package mapping. To make use of the new change
simply add the -m <element name> to allow install-packages
to know which element namespace to use when installing packages.

Use of the new -m option is off by default.

As part of this change we also updated install-packages
to use getopt for in script argument parsing.

e02dbd717b Stop using bash arrays for whitelisting in yum
Using -n for bash arrays was a little bit bad, and also resulted in
errors when running under set -u. Wean the yum element off the array
and switch to a straight string.

1a70916bca set -u doesn't permit bash arrays to test -n
Although set -u allows empty WHITELIST=() list to be set, you can't test
-n "$WHITELIST".  Looks like the intention of the commit that caused
this issue (Change-ID Iad2d490c86dceab148ea9ab08f457c49a5d5352e) is to
set a policy to prevent future use of bugs due to unbound variables.

Thanks StevenK for pairing with me and helping me hone my bash skills.

16be6d7ce0 set -u and -o pipefail everywhere
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.

1c07d4ba1a Remove All Rights Reserved
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.

381ff6ab1d Fix set -eu and pipefail failures
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.

c9a6aef9f4 Add yum element.
The yum element provides for specific customizations
for yum based distros.  The included customization is
a yum cache mounted outside of the chroot so that yum
downloaded packages are reused on subsequent image builds.
