Fix clang build: rewrite avltreeb into avltreen, requires new skalibs

 Thanks John Regan for the report. His fix idea duplicated the
pointers to storage and freelist; there's no way to support a
C99 avltreeb without duplicating the avltreen functionality,
so I ended up scrapping avltreeb in skalibs.
