e4e23897a1 Refactor: block-device filesystem creation, mount and fstab
This patch finalizes the block device refactoring.  It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.

Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.

Notes:

 * unmount_dir : modified to only unmount the subdirs mounted by
   mount_proc_sys_dev().  dib-block-device unmounts
   $TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9)

fea6ab1624 Use sphinx warning-is-error
Sphix 1.5 (I9e7261c4124b71eeb6bddd9e21747b61bbdc16fa) includes
"warning-is-error" which supersedes pbr's warnerrors.  Enable this and
fix up the resulting failures

 - trailing lines for lists in element_deps directive
 - missing README's that are linked
 - syntax error and highlighting in building instructions

a8953dd277 block-device: change top level config from dict to list
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.

ec7f56c1b2 Refactor: block-device handling (partitioning)
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.

9d13084c41 Add squashfs output image format
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.

5e2330d89c Put MKFS_OPTS after filesystem type
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

3d48a528c1 Refactor: block-device handling (local loop)
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.

tmpfs. The  correct user guide to have this section, is the user guide
about image building rather than the installation user guide.

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.
