V4: Build wic images with bitbake

Hi,

This is hopefully last version of the patchset.
I've changed location of .wks and .bb files as Richard suggested.

The following changes since commit 0f84702f0811cba4b6e6e890d478f6e98937b831:

image_types.bbclass: add wic image type (2015-08-30 21:38:23 +0100)

are available in the git repository at:

git://git.yoctoproject.org/poky-contrib ed/wic/wic-image-type
http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=ed/wic/wic-image-type

oe-selftest: test generation of <image>.env
wic-image-minimal: add wic image recipe and .wks
