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.

Fixes bug 1184943
Adding an element that allows other elements to register
repositories it would like to be retrieved for it.
Doing this outside of the chroot allows locally cached
repositories to be used. It also gives the ability to d-i-b
to specify what revision to use if an alternative to the
most recent is required.
Effectively allowing a CI system to test d-i-b and elements
without being effected by unavailable git repositories or
breakages in actively developed source code being used by
the elements.

Fedora's partprobe does not create devices the same way it does on
Ubuntu. Instead of using partprobe, this patch uses kpartx, which
works on both Fedora and Ubuntu.

The recent change to use loopdev instead of nbd stopped
honoring the DIB_IMAGE_SIZE setting.
This change adds it back, by resizing the image to
DIB_IMAGE_SIZE GB, if specified. If unspecified, it resizes
the image to (actual usage + 20%), as it did before this change.

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.

The element vm is the only one creating a partition in the disk.
If not included, it will ask for sudo password to format or mount
the whole nbd disk or disks with multiple partitions.
