libfdt: Remove leading underscores from identifiers

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.
