ext/enumerator, common.mk (OBJS, enumerator.$(OBJEXT)): Make the

* enumerator.c: New method: Enumerable::Enumerator#with_index.
* enum.c (enum_each_with_index): Enumerable#each_with_index now

block is given. Enumerable#enum_with_index, formerly defined in
the enumerator module, is kept as an alias to each_with_index
for backward compatibility.
