Add a --options flag that allows disk-image-create to send custom
options to qemu-img calls. It is useful for forcing compat into
qemu-img created images.
Usage:
disk-image-create --qemu-img-options compat=0.10 base ubuntu

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.

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'
Expanded element dependencies to:

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.

In some instances, the content of the image may want to convey specific
resolv.conf settings. For instance, if unbound is installed, it's also
desirable to set resolv.conf to point to it.
Short circuit diskimage-builder's friendliness around resolv.conf files
by not dying in a fire if it finds the file to be immutable.

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
we will sometimes want to keep the source, and sometimes not. However
for the main image itself, the temp copy is never kept, so use mv
rather than cp and avoid the excess IO.

On some systems ldd gives a slightly different output for VDSOs. It doesn't
contain a '=>'. E.g.:
linux-vdso.so.1 (0x00007fff2f4a6000)
instead of:
linux-vdso.so.1 => (0x00007fff2f4a6000)
This patch simply skips all entries in the ldd output which don't expand to a
path name to workaround that.

cleanup for ramdisk failed to umount TMP_BUILD_DIR with device or
resource busy error.
The patch unmounts all the mountpoints under TMP_BUILD_DIR and
detaches loop devices associated with TMP_IMAGE_PATH.
The unmounts are applied with both force(-f) and lazy(-l)
options. Force option is only for NFS mounts, it's kept here since no
harm for lazy option.

The sbin paths (/sbin, /usr/sbin, /usr/local/sbin) need to be in $PATH.
Since $PATH is set in the build environment from the host, if the host
does not have these paths set, they need to be added to $PATH. In
particular, they must be set for apt-get which calls out to ldconfig,
start-stop-daemon, etc.
The previous check was insufficient because if you had /usr/sbin or
/usr/local/sbin in your $PATH, the addition to $PATH was not done since
the "if" statement evaluated to true.

Commit c7d80dd (Cleanup mount points automatically) removed the unmount
of $TMP_MOUNT_PATH/tmp/ccache in run_d_in_target() and moved the
"rm /tmp/ccache" to elements/base/finalise.d/02-remove-ccache. There
are two problems with this:
1) Not unmounting at the end of run_d_in_target() results in tmp/ccache
being bind mounted muliple times on top of itself (three times, if you
just run `disk-image-create base`). It is eventually unmounted, but
somehow the auto unmount code is confused, and tries to unmount it
one more time than it was mounted, which results in an error like
"umount: /tmp/image.THQkZxQa/mnt/tmp/ccache: not mounted".
This doesn't actually break anything, but it's a little messy.
2) "rm /tmp/ccache" in elements/base/finalise.d/02-remove-ccache never
succeeds in removing /tmp/ccache, because that hook is invoked by
run_d_in_target(), *while* /tmp/ccache is mounted.
This present commit solves the above by moving the ccache setup glue out
of img-functions and into the base element's root.d. This has the
following implications:
1) lib/img-functions is a little cleaner.
2) /tmp/ccache is available in the chroot during the root, extra-data,
pre-install, install and post-install stages. It is not available
during block-device, finalise and cleanup stages as it will have been
automatically unmounted by then.
3) /tmp/ccache won't be setup if you're building an image that doesn't
include the base element.

A problem with unmounting the dev filesystem in Ubuntu images caused
the umount of the /dev bind mount to fail, which left it there to be
removed during the mv -t step, causing the build host's /dev to be
wiped out.
The lazy umount will detach it from the filesystem hierarchy and then
clean up the mount reference later.

In some scenarios, the required space in the tmpfs partition can be
larger (or smaller) than the default one, producing errors due to
the lack of enough space (or performance penalties for not using
tmpfs).
Using --min-tmpfs <size>, we can hint the working set size we'll need
and let dib choose to avoid or use tmpfs.

When compressing an image, this is done in the same dir where the raw
image resides, doubling the amount of space needed (scarce when
using tmpfs), and then it's moved to the .cache folder in disk.
Combining these two functions, we reduce the amount of space needed
in the tmpfs partition (when in use), and the compressed image is
created directly on the .cache folder disk, so there is no need to
move the compressed image after the process into disk.

Most of our build process runs as root and the overhead of explicitly
tracking sudo commands in the shipped sudoers.d file, plus the
operational overhead of keeping the sudoers.d file updated on build
hosts over time, is now considered to be unnecessary.
Instead, we now document that the build process will expect sudo
commands to work and the operator must make this happen (either by
running as root, via sudo -E, or allowing passwordless sudo for the
build user).

then a user will be provided a in target shell taking over from where the
