This fixes a great many sparse warnings on the fdt and libfdt sources.
These are mostly due to incorrect mixing of endian annotated and native
integer types.
This includes fixing a couple of quasi-bugs where we had endian conversions
the wrong way around (this will have the right effect in practice, but is
certainly conceptually incorrect).
This doesn't make the whole tree sparse clean: there are many warnings in
bison and lex generated code, and there are a handful of other remaining
warnings that are (for now) more trouble than they're worth to fix (and
are not genuine bugs).

Running fdtdump without scan mode for an invalid file often
results in a segmentation fault because the fdt header is
not checked.
With the patch the header is checked both in scanning as
well as in non-scanning mode.

1) Remove the double parentheses around two comparisons in checks.c.
The OSX LLVM-based C compiler warns about them.
2) Put an explicit "=" in the TN() macro, in accordance with c99.

This currently displays a hex value without the 0x prefix. Add the prefix
as dtc requires it.

When hacking raw fdt files, it's useful to know the actual offsets into
the file each node appears. Add a --debug mode that includes this.

Now that all utils have converted to the new usage framework, we can
rename to just plain "usage()" and avoid naming conflicts.

Often times, fdts get embedded in other larger files. Rather than force
people to `dd` the blob out themselves, make the fdtdump file smarter.
It can now scan the blob looking for the fdt magic. Once locate, it does
a little validation on the main struct to make sure we didn't hit random
binary data.

This starts a new usage framework and then cuts fdtdump over to it.
Now we can do `fdtdump -h` and get something useful back.

The function that prints a property can be useful to other programs,
so move it into util.

Device tree can store multiple strings in a single property.
We didn't handle that case properly.

The freetype package already installs a binary named "ftdump", so the dtc
package conflicts with that. So rename the newer dtc tool to "fdtdump".
This even makes a bit more sense:
ftdump: [F]lat device [T]ree [dump]
fdtdump: [F]lat [D]evice [T]ree [dump]
