Title: Feature 4890 lazy enumerator

Please, see http://bugs.ruby-lang.org/issues/4890 for more info about enumerator laziness.

Last week I've made this PR #100. But I've faced some problems while trying to push the idea further.

So, here's a straight C implementation of the `Enumerable::Lazy` as suggested in original feature request on bugs.ruby-lang.org.

Only `Enumerable::Lazy#map` added so far but I'm keep working on other methods as well.
