Changes for version 2.0
- complete rewrite (use the hopefully clearer libev hash functions).
- add splice_heap and adjust_heap family of functions.
- speed up _cmp family of functions by using the MULTICALL API.
- clarify comparison function semantics.
- comparison is now >, not >=.
- speed up of everything by taking advantage of the freedom the "no magical/tied stuff is supported" rule.
