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

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.

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.

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.

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.

Manually listing the mount points that need cleanup is not

A user running di-b several times while developing an element may not
want to drop to a shell in all cases but may only want to do so if one
of their in target hooks failed.
This patch gives them the ability to do so, If break=after-error is set
then a user will be provided a in target shell taking over from where the
last failed command left off.

Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.

Many python extensions are built from source each time an image is
built. Repeating these is wasteful, so ccache is employed to eliminate
that waste. A cache dir outside the chroot is used to speed up
subsequent image builds.

Setting up a routine to run at first time the system boot may vary from
distribution to distribution. This patch will remove the logic from the
diskimage-builder code and put it into the elements.
The base element will now deploy a dib-first-boot script and each OS
element will ensure that this script runs at rc.local time. By doing
that we will put the OS specific stuff in the OS elements and remove
the embedded code out of the img-function file.

With systemd rc.local lives in /etc/rc.d and is only run
if the rc-local service is enabled.
This change creates a /etc/rc.d/rc.local symlink, and modifies img-functions

Sudo compiled with the --with-secure-path option enabled (default on
Ubuntu, Fedora and potentially other distros) will cause sudo to ignore
any changes made to the PATH variable in the user's environment (even when
the -E option is used). Also, some distros might not have /usr/local/bin
set in their sudoers secure_path causing the diskimage-builder to fail
when building an image using such distros as host. This patch will force
the inclusion of the /usr/local/bin in the PATH enviroment variable
inside the chroot.

It moves cleanup_dirs and run_d functions from img-functions to
common-functions to allow this.

For machines with low RAM (or no access to /proc/meminfo) the builder
will still run, but will just build inside the filesystem that is
hosting /tmp. This will result in a slower build (especially if there
are a lot of .deb packages installed).

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.

Also modified dib-run-parts to apply a more workable solution for
filtering out unwanted files such as editor backups and VCS.
The script is installed in its own element, depended on by the OS
specific ubuntu element. This is because the ubuntu element (and
later other OS's) are responsible for populating the root filesystem.
If we try to install this in base, the root filesystem will look to
be populated already and we will skip automatically choosing ubuntu.
