Remove leading underscores from identifiers

In a number of places, dtc and associated tools and test code use
leading _ characters on identifiers to flag them as "internal", an
idiom taken from the Linux kernel.  This is a bad idea in a userspace
program, because identifiers with a leading _ are reserved for the C
library / system.

In some cases, the extra _ served no real purpose, so simply drop it.  In
others move to the end of the identifier, which is a convention we're free
to use for our own purposes.
