lib/libfdt was the central sync point of libfdt,
but the situation changed by the switch to the bundled DTC approach.

Now we have two copies in lib/libfdt and scripts/dtc/libfdt.

See Linux.
scripts/dtc is periodically synced with DTC, including scripts/dtc/libfdt.
lib/fdt* are wrappers to scripts/dtc/libfdt/fdt*
I think this is very successful.

So, I am trying to leave only scripts/dtc/libfdt
and turn others into wrappers of them.
