37a53354ec Add IMAGE_ELEMENT_YAML and get_image_element_array
These new variables are a list of elements chosen for the build along
with their full paths.  For Python elements, IMAGE_ELEMENT_YAML is a
YAML formatted list that can be easily parsed.  For bash elements,
"get_image_element_array" will produce an associative-array of the
same (working around lack of array export in Bash).

This list is intended for consumption of elements who need to copy
files from other elements, such as pkg-map and svc-map.  As discussed
in I2a29861c67de2d25c595cb35d850e92807d26ac6, this list has already
been pruned and had overrides processed, so it is safe to simply walk
over this list with no further processing.

Since we're presenting the element list in a couple of different ways,
we combine it all into the element-info script.  It will output an
eval-able string that declares the appropriate variables.

I've added some inline documentation so they still appear in grep.
The documentation is updated with examples, and moved to a more
appropriate location as a sub-section of the element sytle guide.

To test this out, use the associative-array in generate_hooks, where
we can now find the element's directory without searching.

5e1fcca299 Fix the bug that "mktemp: failed to create directory"
In the function "run_in_target", it is failed that force an empty
TMPDIR inside the chroot. The TMPDIR is still the user defined
tmp dir. Due to the TMPDIR dir is not exist, using "mktemp" to
create tmp dir is failed.

a6a5c385eb Refactor: rename temporary directories
The temporary directories for image creation and building the OS both
started with 'image' as their names followed by some random
characters.  During debugging this is annoying, because on first sight
it is not clear, where which files are stored.

This patch renames them to dib_build.XXXXXXXX and dib_image.XXXXXXXX.

This patch introduces no user-visible change:
the temporary directories are only used during the
run of disk-image-builder.

b365d3c833 Refactor: remove unused functions
There were a couple of functions which were unused:
ensure_nbd, map_nbd, unmount_qcow_image, mount_qcow_image, ensure_sudo
Because some of them use 'trap ... EXIT' this hinders introducing a
separate exit phase - therefore they are removed.

(It would also be impossible to use them in the current setup, because
they overwrite the 'trap ... EXIT' of the disk-image-creates 'main'.)

7550d25db0 Export die() function
I realised I'd been using die() in a few places assuming it was
available, but it wasn't exported.  I guess it didn't matter because
whatever was wrong, we were failing anyway :)

This exports the function to make it available to sub-processes, which
should remove the need to source it as done in several places.

0d1d6bec7c Properly fail/trap in eval_run_d
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.

edc06a20e5 Install docker for tests
We have some test cases which attempt to build docker images, therefore
we need docker.

Fix a few bugs that showed up when we run docker tests - we need to
docker rm with sudo and docker images don't always have a /tmp so check
before unmounting it.

5b6716cee8 Use fstrim to prep the block device
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.

5184d02a7c Zerofree the image if possible
If the image has an ext filesystem and the zerofree utility is present
on the build system then run zerofree. This should make images as
compressable as possible which is a nice feature when building
compressed qcow2 images.

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).

12cb94a75d Fix unmount/remove race in cleanup_build_dir
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.

d9ce041237 Prevent overwriting of user modified blacklist.conf
The ramdisk-functions overwrites user modified
/etc/modprobe.d/blacklist.conf with a single entry
"blacklist evbug". Due to this, ramdisk fails to recognise
the hardware/disks etc for which user has modified
/etc/modprobe.d/blacklist.conf.
The commit enables copying all the *.conf files under
/etc/modprobe.d to the ramdisk. It creates
a config file /etc/modprobe.d/blacklist-dib-ramdisk.conf
instead of overwriting /etc/modprobe.d/blacklist.conf.

494a833987 Add #!/bin/bash to library functions
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.

987a832351 Cleanup the build directories earlier
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.

37572a548c Cleanup /tmp in the guest
Clean all the content in the /tmp directory of the guest, leaving the
directory itself (usually has special attributes).

Modern distributions usually either setup a tmpfs on /tmp, or clean it
at every boot, so the leftovers will be just few bytes in the generated
image.
Regarding other distributions, a clean /tmp at their first boot will
surely not be a bad idea anyway.

In I084aff7e449f5de811a6169ec90e352ada7da439 we attemped to address a
bug for systems which dont have a path that works well for inside a
chroot. Turns out there were multiple issues:
 * The PATH we were setting was after we attempted to call sh.
 * PATH was being set in a sibling process to the command being run.
 * PATH was not being exported so it was not effecting child processes.

Using env to set a sane path before we attempt to run our commands
addresses these issues.

4a2939c207 Append full path to img-functions:run_in_target
The build host might not necessarily have a complete set of dirs
required in its PATH. It will likely be better to statically code a
complete(ish) set of PATH entries inside the function.

Some distros (ex: archlinux) are lacking some dirs commonly found in a
PATH. If this is used as a host OS, it will transfer this incomplete
PATH into the chroot, where other guests (ubuntu, centos) will fail to
find basic binaries due to the lack of a /bin entry.
