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.

I've recently signed up dtc for Coverity Scan coverage. This adds magic
to the .travis.yml file to submit builds to Coverity for analysis.

To make sure the Makefile behaves in both cases, make Travis matrix builds
with and without swig installed.
