However, that wouldn't help much with the allocation/leak problem,
though at least it would be easier to use. It could also *try* to re-use
the current allocation if the new content is of smaller or equal size.

I thought that dtc tried to aggressively save space by folding identical
strings. If you tried to reuse a property that had its contents shared
with another one, you would get interesting results I guess.

It used to be only property names, unless that has changed in recent
dtc. But that's a good point, we probably want a flag in struct property
like we have for nodes, indicating whether it comes from the original
fdt data pool or not.

This is similar to what the "OF_IS_DYNAMIC()" thing on sparc
indicates.
