Similar to what we did with mapping_interval_tree*(), let's declare
anon_vma_interval_tree*() in terms of anon_vma rather than rb_root_cached.

In each case the rb tree referenced is &anon_vma->rb_root, so just pass
anon_vma and the functions can figure this out themselves.

Additionally, rename 'node' to 'avc', 'index' to 'pgoff_start', and 'last'
to 'pgoff_last' to make clear what is being passed.

Finally express page offsets in terms of pgoff_t to be consistent.

No functional change intended.

Thanks :)

I have a vaguely similar comment as for the file part (names could be
simpler, doesn't really matter whether it's an interval tree or possibly
even a tree), but I care less strongly about anon rmap :)

And yeah ack, let me agonise over that a bit :P
