The fdtoverlay utility reads in the base fdt blob, then expands it to make
room for all the overlays requested. However, it uses the totalsize field
of the base blob without verifying that it actually read all of it in (it's
possible the blob file could have been truncated).

Since libfdt support overlay application on FDT blobs, provide
a command line tool that applies an arbitrary number of
overlays, one after another to a base fdt blob and output
the result in the given file.
