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.
This patch adds exported accessor macros for the various flat device
tree header fields to libfdt.h. This necessitates moving some of the
byte-swapping functions.

This patch fixes some completely bogus error checking logic from the
nop_property testcase (resulted from a cut-and-paste error).

Without this rather odd constrained pattern rule, make attempts to build
dumptrees using the default %: %.c rule instead of the defined %: %.o and
%.o: %.c rules.
