Since we use a global variable in installsystems.printer to store the arrow
level, we have to keep this module in scripts global context.

Since the dmod and fmod setter take a string as argument and convert them to a
base 8 integer, we don't need to check and convert in integer with the
configobj validator.

The command 'upgrade_db' create a dummy repository (to the current version) and
add each images/payloads from the repository to upgrade. Symlinks are used to
avoid copy. Old database is still available in repository as db.bak.

Old repository are still usable.
Database changes:
Add is_min_version and image_format in image table.
Add repository table which contain database uuid, version and motd.

Compressors are specified in description file.
For example:

[compressor]
gzip = *
none = *.gz, *.bz2
bzip2 = rootfs*

This description file set gzip as default compressor, do not compress payload
which end with .gz and .bz2 and use bzip2 as compressor for payload matching
'rootfs*'

configobj keeps the order of options in config file, we don't need to use
OrderedDict.

Image version now accept a string of digit separated by dots and extra char as
a qualifier (~ or +).

Example:
1.2.3.4~dev < 1.2.3.4 < 1.2.3.4+dev

Old repositories are still compatible thanks to sqlite type affinity
(https://www.sqlite.org/faq.html#q3

).

We use a package version comparison algorithm for image version comparison
inspired by Debian.

New pattern is: [repository/][image][:version] (image is now optional).
Allow to select images in repository without globbing: 'is list repository/'
now work as 'is list repository/*'.
Same for version, for example: 'is list :*dev' work as 'is list */*:*dev'.

For example, if you have the following scripts in an image:
lib/
   |- 01-foo.py  (module 'foo')
   |- 02-bar.py  (module 'bar')
module 'bar' (and subsequent) could import and use content from module 'foo'.

The setup and payload directories and description file are the strict minimum
to build an image.
Payload directory is needed because build scripts can edit or create payloads.
