Add a 'wic list source-plugins' command enabling users to get a list
of valid partition --sources. This is useful not only for determining
sources to use in .wks partition statements, but also for making sense
of errors in .wks partition processing.

If wic is running as raw mode, it's better to check if BBLAYERS
is valid before inspect it.
No functional changes.

.wks file are looked in 'scripts/lib/image/canned-wks' directory on all
BBLAYERS variable returned by bitbake environment. If found, it will
be used.
The user could create your own .wks and keep it inside its layers. For
now the path must be <layer-dir>/scripts/lib/image/canned-wks.

Move find_bitbake_env_line() since they're going to need to be
accessible from source plugins.

bitbake_env_command will choke if it isn't given an image, make sure
it does the right thing in that case.

Hook up the existing --debug option to toggle the wic debug loglevel,
which is indispensible when things go wrong, and make it easy to use
from the command-line.

Add get_bitbake_var() and bitbake_env_lines() functions for use by
plugins, which will need access to them for customization.

If one of these isn't found, it won't be initialized and will throw an
UnboundLocalError.

Reuses the mic/livecd infrastructure but heavily subclasses and
modifies it to adapt to the special needs of building images from
existing OpenEmbedded build artifacts.
In addition to the OE-specific mic objects and modifications to the
underlying infrastructure, this adds a mechanism to allow OE kickstart
files to be 'canned' and made available to users via the 'wic list
images' command.
Two initial OE kickstart files have been added as canned .wks files:
directdisk, which implements the same thing as the images created by
directdisk.bbclass, and mkefidisk, which can essentially be used as a
replacement for mkefidisk.sh. Of course, since creation of these
images are now driven by .wks files rather than being hard-coded into
class files or scripts, they can be easily modified to generate
different variations on those images. They also don't require root
priveleges, since they don't use mount to create the images. They
don't however write to media like mkefidisk.sh does, but rather create
images that can be written onto media.

Initial implementation of the 'wic' command.
The 'wic' command generates partitioned images from existing
OpenEmbedded build artifacts. Image generation is driven by
partitioning commands contained in an 'Openembedded kickstart' (.wks)
file specified either directly on the command-line or as one of a
selection of canned .wks files (see 'wic list images'). When applied
to a given set of build artifacts, the result is an image or set of
images that can be directly written onto media and used on a
particular system.
'wic' is based loosely on the 'mic' (Meego Image Creator) framework,
but heavily modified to make direct use of OpenEmbedded build
artifacts instead of package installation and configuration, things
already incorporated int the OE artifacts.
The name 'wic' comes from 'oeic' with the 'oe' diphthong promoted to
the letter 'w', because 'oeic' is impossible to remember or pronounce.
This covers the mechanics of invoking and providing help for the
command and sub-commands; it contains hooks for future commits to
connect with the actual functionality, once implemented.
Help is integrated into the 'wic' command - see that for details on
usage.
