In a lot of places libfdt uses a leading _ character to mark an identifier
as "internal" (not part of the published libfdt API). This is a bad idea,
because identifiers with a leading _ are generally reserved by the C
library or system. It's particularly dangerous for libfdt, because it's
designed to be able to be integrated into lots of different environments.
In some cases the leading _ has no purpose, so we simply drop it. In most
cases we move it to the end, as our new convention for marking internal
identifiers.

This commit adds a license header to fdt.h and libfdt_env.h
because the license was omitted.

Projects such as linux and u-boot run sparse on libfdt. libfdt
contains the notion of endianness via usage of endian conversion
functions such as fdt32_to_cpu. As such, in order to pass endian
checks, libfdt has to annotate its fdt variables such that sparse
can warn when mixing bitwise and regular integers. This patch adds
these new fdtXX_t types and, ifdef __CHECKER__ (a symbol sparse
defines), includes the bitwise annotation.

At present fdt.h #includes stdint.h. This makes some sense, because fdt.h
uses the standard fixed-width integer types. However, this can make life
difficult when building in different environments which may not have a
stdint.h. Therefore, this patch removes the #include from fdt.h, instead
requiring that users of fdt.h define the fixed-width integer types before
including fdt.h, either by themselves including stdint.h, or by any other
means.
Since its beginning, libfdt has used an incorrect definition of the
format for a property, putting the name offset before length, rather
than the other way around as described in booting-without-of.txt.
This corrects the error, making libfdt actually produce and use trees
which are compatible with the kernel and dtc.

v17 of the blob format adds a field for the size of the structure
block, but is backwards compatible with v16. This patch introduces
definitions for the new field, and uses it to improve the bounds
checking in the read-only code. It also cleans up the sequential
write code using it: we no longer need to borrow the version field as
a write pointer.
