Added new pager interface, IPager2, whose write interface enables forcing the user to handle a page update causing a copy to a new Page ID. Implemented FIFOQueue<T> which uses pages of T stored in a Pager2 instance to implement a FIFO queue. Implemented COWPager, a copy-on-write Pager2 in which all page writes cause a change of Page ID. VersionedBTree, still only operating in single-version mode, now uses Pager2.
