Now that the wrapper supports 64-bit builds, we see warnings when
attempting to cast pointers to int. Use unsigned long instead.

David Gibson suggested that since we are now unconditionally copying
the dtb into a malloc()ed buffer, it would be sensible to add a little
padding to the buffer at that point, so that further device tree
manipulations won't need to reallocate it.
This implements that suggestion.

Some platforms have variants that can share most of a flat device tree but need
a few devices selectively pruned at boot time. This adds del_node() to ops.h
to allow access to the existing fdt_del_node().

If the vmlinux binary in memory is larger than 4 MiB than it collides
with the initial boot code which is linked at 4 MiB in case of cuBoot.
If the the uncompressed image size (on disk size) is less than 4 MiB
then it would fit. The difference between those two sizes is the bss
section. In cuBoot we have the dtb embedded right after the data
section so it is very likely that the reset of the bss section (in
kernel's start up code) will overwrite the dtb blob. Therefore we
reallocate the dtb. Something similar is allready done to the initrd.

Add the ability to find a device node by just what its compatible with.
This is useful in cases that we don't have a prop to find the node with.

devp_offset_find()
Many operations, as currently used in the wrapper, assume they can
pass NULL and have it be treated as the root node. However, libfdt-wrapper
converts NULL to -1, which is only appropriate when searching for nodes,
and will cause an error otherwise.

fdt_wrapper_create_node passes a variable called offset to offset_devp(),
which uses said parameter to initialize a local variable called offset.
Due to one of the odder aspects of the C language, the result is an
undefined variable, with no error or warning.

This incorporates libfdt (from the source embedded in an earlier
commit) into the wrapper.a library used by the bootwrapper. This
includes adding a libfdt_env.h file, which the libfdt sources need in
order to integrate into the bootwrapper environment, and a
libfdt-wrapper.c which provides glue to connect the bootwrapper's
abstract device tree callbacks to the libfdt functions.
In addition, this changes the various wrapper and platform files to
use libfdt functions instead of the older flatdevtree.c library.
