Btrfs II (#838)

* Btrfs with encrypted partitions.
We have changed installer.mount_ordered_layout into a series of loops
* open the encrypted devices
* manage btrfs subvolumes
* mount whatever
* create kyefiles for encrypted volumes
We have simplified the btrfs subvolume manager

We merged the locale branch as it is needed here

* We allow only the creation of keyfiles if the partition does not contain the root mount point.
Also, adapt examples/only_hd to the new __init__.py
Also, assorted flake8 warnings

* Cleanup code

* Naming schema for encrypted volumes
revert global locale association (provisional)

* We introduce the option of defining mount options in the partition dictionary.
It has forced us to define two new entries in this dictionary:
* format_options (formerly options) for mkfs options and
* mount_options for mount -o ones.
The different meaning of compress between partition and subvolumes is treated

* Function lib/disk/btrfs.py mount_subvolume marked as deprecated
Code cleanup.

* format_options now filesystem.options

* format_options now filesystem.format_options
mount_options  nof filesystem.mount_options

* flake8 uncovered a slip in the code
