interval_tree: allow bulk queries

This adds an API to interval_tree to allow it to be queried in "bulk".
The caller passes a set of query points and a callback, and the tree
calls the callback once per <interval, point> pair.

This has much better CPU cache efficiency than a lot of separate
queries. Additionally, doing 'Q' queries in bulk is logarithmic in Q
rather than linear.

More importantly, this will allow rowset-wise processing of batches of
writes, which opens up big perf wins in later patches in this series.
