* fs_{write|read}_pages() now has an additional argument "mayBlock".

* the page writer don't allow to block, while all other writers do. This fixes
  bug #1509. The reason the page writer needs this is because it marks several
  pages from different caches as busy.
* Fixed a warning about ASSERT being defined already in BFS, since
  util/DoublyLinkedList.h now includes debug.h.
