Catch unsigned 32bit overflow when parsing flattened device tree offsets
We have a couple of checks of the form:
if (offset+size > totalsize)
die();
We need to check that offset+size doesn't overflow, otherwise the check
will pass, and we may access past totalsize.
Found with AFL.

dtc/tests: don't include fdt.h prior to libfdt.h
tests will need fdt type definitions provided in a subsequent patch
to libfdt_env.h. Since libfdt.h includes libfdt_env.h in the right
order anyway, just remove the fdt.h include.

dtc: Implement checks for the format of node and property names
This patch adds checks to the checking framework to verify that node
and property names contain only legal characters, and in the case of
node names there is at most one '@'.
At present when coming from dts input, this is mostly already ensured
by the grammer, however putting the check later means its easier to
generate helpful error messages rather than just "syntax error". For
dtb input, these checks replace the older similar check built into
flattree.c.
Testcases for the checks are also implemented.

dtc: Add missing copyright notice for dumptrees.c
When I released libfdt, I forgot to add a copyright notice to
dumptrees.c (probably because the program is so trivial). Apparently
the lack causes trouble for Debian, so this patch adds one. I've gone
through the git history and double checked that no-one has touched
this file except me (and I barely have myself since its initial
commit).

Merge libfdt into dtc.
Having pulled the libfdt repository into dtc, merge the makefiles and
testsuites so that they build together usefully.
