In phases which are called from eval_run_d (block-device.d) we do not
listen to exit 1's nor do we allow break=after-error. This is because
the run_d function is called in a subshell in order to grab its output.
This also turns on pipefail in the main disk-image-create script.

Cleanup this function to work with a symlinked directory. Document
it's behaviour more exactly, and add a simple unit-test for it (not
run by default, due to doing things like mounting and unmounting
system dirs on a live system, which doesn't seem safe for CI. But it
is useful for developers ensuring sanity).

Due to a bug in how we were running some of our phases we were not
detecting some nonzero exit's. When this is fixed, dib fails early during
cleanup (leaving some resources attatched) due to not propertly
accounting for pipefail.

With a slow file system, umount can return 0 and the immediately
following remove can fail with a "Device or resource busy" error.
This happened in DevStack in disk-image-create where unmount_image
is followed by an immediate cleanup_build_dir.
Solution is to apply same logic from bug 1332521 to allow the
remove to retry on failure (up to 5s) in case the umount has not
completed.

Currently when these files are opened your editor doesn't know what to
do with them. Add #!/bin/bash to library functions so that editors,
diff-tools, etc can do syntax highlighting.
There are other ways to skin this cat, such as renaming to ".sh",
adding -* style editor flags, etc. We had this discussion in DevStack
too, and came to the conclusion the simplest thing that works for
everyone is to just put the #! at the top.

Temp dirs are created with mktemp and thus belong to the user. There
is no need to chown them unless we used `mount -t tmpfs`.
Move chown under the tmpfs_check conditional.

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.

By that point in the build it isn't generally useful, and it causes

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.

The element builds dracut from source on Ubuntu because the
Ubuntu dracut package is broken and very old, so it can't be
installed properly and causes a number of other issues that
are fixed by using a newer version of Dracut.
This initial version should work in virtualized environments.
Further validation of its suitability for real baremetal
deployments will need to be done in the future, but this should
be sufficient to enable that work.
Regarding Dracut specifically, in order to limit the changes
needed in the existing scripts this element continues to use a
cut down version of the /init script that we were building for the
existing ramdisk. However, instead of running it as pid 0 it is
run as a Dracut pre-mount hook. This allows Dracut to set up all
of the hardware and system bits, while falling early enough in the
Dracut sequence to complete the deployment before Dracut would try
to boot off the hard disk.

Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.
This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.

We need to be able to do install.d like things for ramdisks
themselves, but install.d runs outside the ramdisk context - and its
likely to break peoples brains if we mangle the two together - so this
adds a new hook point, ramdisk-install, specifically for installing
things into the ramdisk.

The two duplicated functions, save_image and finish_image will move

duplicating its code exactly.

Ensure the return code of element-info is actually checked by moving the
export IMAGE_ELEMENT to the subsequent line.
A recent change (Ic0a061995e2ae708c95a535cba6237bff58f7d93) exported the
IMAGE_ELEMENT variable. This caused the return code of element-info to not
actually be checked, since the export command is now checked instead and
almost always will return 0.
This caused a misleading error message when using diskimage-builder with an
unknown element since the script didn't exit when it should have:
$ bin/disk-image-create -a amd64 foobar vm
Building elements: base foobar vm
ERROR: Element 'foobar' not found in 'bin/../elements'

Adds a new pkg-map element which can be used to install
packages based on an in element 'pkg-map' JSON config
file format.
As part of this change we expose DIB's IMAGE_ELEMENT variable
so that we can have access to the element names which are being
installed in a clean manner.
This change is intended to decouple elements from DIB
and allow new elements to support multiple distributions
(with various package naming schemes) without having to
constantly maintain DIB's various bin/map-packages files.

If the tmpfs being used to hold the image filesystem is close to being
full then housing the raw disk image in the same place can be
problematic as it tends to grow faster then the filesystem shrinks when
data is being moved into it.
Putting them both into separate tmpfs's will allow there to be an
overlap where they jointly use more then the size limit for a singe tmpfs.

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.

save_image is used to copy kernel and ramdisks out of the image, which

for the main image itself, the temp copy is never kept, so use mv
