This adds a generic Status call in the Driver api and
implements if for the devicemapper backend.
The status is an array of key/value strings rather than a map so that
we can guarantee some static order of the docker info output.

Add the methods to the Driver interface
to force the drivers to implement the methods

This moves the Diff() operation to a separate Differ interface and
implements a fallback that uses the Changes() results to encode
a diff tar.

We now always initialize devicemapper on startup, so
no need for the code that did lazy initialization, we
just delete it.

Udev escapes "," used in device names to 0\x2c which breaks libdevmapper.
Instead use : to escape minor and minor which works.

The way devices are mapped is a bit more complex than before.
This implements the method from new_decode_dev in:
https://github.com/mirrors/linux-2.6/blob/master/include/linux/kdev_t.h
Which is what is needed on kernels > 2.6

There is no need to have this be writable, and there is a chance
that e.g. atime updates will cause writes to the image which is
bad for disk use wrt sharing between all containers.

As per the thin provisioning docs for creating the pool:
$data_block_size gives the smallest unit of disk space that can be
allocated at a time expressed in units of 512-byte sectors.
$data_block_size must be between 128 (64KB) and 2097152 (1GB) and a
multiple of 128 (64KB). $data_block_size cannot be changed after the
thin-pool is created. People primarily interested in thin provisioning
may want to use a value such as 1024 (512KB). People doing lots of
snapshotting may want a smaller value such as 128 (64KB).
The switch from 512 (which we used before) to 128 (recommended above
for lots of snapshoting) means a simple container creation (based on the
mattdm/fedora:f19 image) adds 1 MB of diskspace rather than 3.6.
This seems more in tune with how docker is typically used.

This way the devicemapper prefix stays stable even if we're not
using loopback mounted devices.
