Add a node argument to __of_node_alloc() and rename it to
__of_node_dup() so that it can also be used to duplicate a node with
its properties. This is important for the overlay code so that it can
create new nodes without using separate changeset items for every single
property.
At the same time rework the overlay code to use the new function and
drop the extra changeset items.

The overlay code needs to construct a new full_name from the parent name
and the node name, but the current method has to allocate and then free
an temporary string which is wasteful. Fix this problem by using vargs
to pass in a format and arguments into __of_node_alloc().
At the same time remove the allocflags argument to __of_node_alloc().
The only users all use GFP_KERNEL, so there is no need to provide it as
an option. If there is ever a need later it can be added back.

v3.18-rc6 contains an important DT bug fix, c1a2086e2d, "of/selftest:
Fix off-by-one error in removal path" which affects testing of the
overlay patch series. Merge it into the devicetree/next staging branch
so that the overlay patches are applied on top of a known working tree.

This is unit testing code. It should use that name because it makes more
sense than 'selftest'. Rename the files to match and rename the config
variable.
