libfdt is never supposed to access memory outside the the blob, or outside the sub-blocks within it, even if the blob is badly corrupted. We can leverage valgrind's client requests to do better testing of this. This adds a vg_prepare_blob() function which marks just the valid parts of an fdt blob as properly initialized, explicitly marking the rest as uninitialized. This means valgrind should catch any bad accesses. We add a call to vg_prepare_blob() to load_blob() so that lots of the existing testcases will benefit from the extra checking.
