Richard Purdie 19f290f223 bitbake: data_smart: Add CoW approach for overridedata
Using deepcopy() caused a major performance regression. Turns
out we can work with a shallow copy as long as we force the
recreation of any list that we change, effectively a poor mans
CoW. This isn't too invasive and avoids the huge overhead of
deepcopy so this seems like the best way to have performance and
a working data store.
