On my machine, for an unmodified oe-core. when I run the wic-related
oe-selftests I see:

	successes=93, skipped=1, failures=0, errors=1

with these changes, this is what I get on my machine:

	successes=91, skipped=1, failures=2, errors=0

to run:
	$ sudo .../openembedded-core/scripts/runqemu-gen-tapdevs <your numeric gid> 4
	$ oe-selftest -v -r wic.CLITests wic.ModifyTests wic.Wic wic.Wic2

There are still 2 test cases that are eluding me, but I wanted to get
this patchset out there in case anyone was interested in looking at it,
and to see how it will do on the AB (knowing that there is a little more
to do).
