add simple refcounting scheme to concurrentSkipList.  This solves the
problem where a deleted node points to another deleted node, and we
only have a hazard pointer for the first node.

add hazard pointers for update using the smallest free slot first.  The
old method left a race condition, since hazard_scan stops at the first
null pointer.

7660467f8e Refactor page implementation to use multiple include trick (so the backing representation can be changed). 
Also, fix apparent bug in stasis_page_fixed_set_record_type().

Otherwise, this change should not make any semantic changes.
