Begin weaning user-only away from PageDesc. Since, for user-only, all TB (and page) manipulation is done with a single mutex, and there is no virtual/physical discontinuity to split a TB across discontinuous pages, place all of the TBs into a single IntervalTree. This makes it trivial to find all of the TBs intersecting a range. Retain the existing PageDesc + linked list implementation for system mode. Move the portion of the implementation that overlaps the new user-only code behind the common ifdef.
