Integration test to test the basic functionality of dev-install and gmerge.

This module contains a test that runs some sanity integration tests against
a VM. First it starts a VM test image and turns it into a base image by wiping
all of the stateful partition. Once done, runs dev_install to restore the
stateful partition and then runs gmerge.

Right now I have the gmerge test not run as it's having some funky portage
issues (I could switch it to qemacs and it'll work -- see TODO).

BUG=chromium-os:12388 chromium-os:37901
TEST=Ran it --- many many times.
