index: embed nodetree in index object to avoid reference cycle
Since the index has a reference to a nodetree and the nodetree has a
reference back to the index, there is a reference cycle, so the index
(and its nodetree) can never be freed. This patch fixes that by making
"nodetree" a plan C struct that the index can embed, and also
introduces a new "nodetreeObject" that is a Python type wrapping the
nodetree struct.
Thanks to Yuya for noticing this and for suggesting the solution.
All tests passed on the first attempt once it compiled (I guess C is
like Haskell in this regard?).
