This new patch replaces the previous patch. As requested, I am splitting up the large issue CLJ-993 into smaller tickets.

Does not depend on any of my other reducer patches, but there will probably be some minor merge conflicts unless it is merged after CLJ-1045 and CLJ-1046, and before CLJ-993.

Currying iterate seems useless, albeit not harmful.

While implementing repeat, I couldn't use currying. Because 1-arity is already reserved for infinite repeat ([n x] and [x], not [n x] and [n] if currying)

How about we just support currying for functions where last param is reducible?

Previous version neglected to include the seed value of the iteration in the reduce.

Should I have made this implement Seqable as well? It wasn't clear to me, because as far as I could see this was the only function in clojure.core.reducers that's generating a brand-new sequence rather than transforming an existing one.
