With the old configuration structure it was only possible
to use one image and one partition layout. The new
block-device configuration uses a list at top level;
therefore it is possible to use multiple instances
of each element type.

During the creation of a disk image (e.g. for a VM), there is the need
to create, setup, configure and afterwards detach some kind of storage
where the newly installed OS can be copied to or directly installed
in.
This patch implements partitioning handling.

The squashfs format brings a couple of advantages over the other
formats. Image is often an order of magnitude smaller and it can
be used natively, either as an initrd, either with loop mount.

We now support tgz (tar.gz) as an output format.

mkfs's arguments are
mkfs [options] [-t type] [fs-options] device [size]
So it seems our MKFS_OPTS are really supposed to be fs-options, rather
than options to mkfs itself.
Why didn't we notice? It's quite a trap -- mkfs.ext2 has a "-t"
option, so when we're calling
$ mkfs -i 4096 ... -t ext4 ...
We actually just fall-back to the default from the mkfs wrapper which
is mkfs.ext2 which works! But when you make that, say, xfs, we're not
calling the right wrapper at all.
Also update documentation

Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.
This patch factors out the creation and deletion of the local
loop image device handling into a python library.
The main propose of this patch is to implement the needed
infrastructure. Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

speedup section explains the user how to sppedup image build by using
tmpfs. The correct user guide to have this section, is the user guide
about image building rather than the installation user guide.

End user docs would benefit from a section about the byte-to-inode
ratio, and why it's set the way it is. This update explains why
and how to manipulate the ratio depending on the intended use.

Our docs are very developer focused. Lets create a separate user guide
to help new users get started.
