index: make most "nt_*" functions take a nodetree
Now that the nodetree has a pointer to the index, we can pass the
nodtree instead of the index. There are few "nt_*" functions left
after this. I'll deal with them soon.

index: add pointer from nodetree back to index
This is always a cycle right now, but it will not be for the nodetree
instances I'm planning to add later (see earlier patch).

index: remove side-effect from failed nt_new()
As pointed out by Yuya in the review of D4108, if realloc() fails, we
would end up with an invalid nodetree instance (with nt->nodes set to
NULL), which means that if it was later accessed again it would likely
segfault. It's probably unlikely that much else happens in the process
if it ran out memory, but we should of course do our best to handle
it. This patch makes it so we don't update the nodetree in this case.
