Why not just make it part of dart:sky?

[abarth-chromium, 2015/06/23 14:43:58]

Yes, we should make it part of dart:sky.  In this CL, I've just made it build in
the same way.  The next step is to merge it with dart:sky.

That change isn't trivial, however, because the code that hooks up the C++ code
to dart:sky is in a different layer of the system than the code that hooks up
the C++ code to dart:sky.internals.  However, we'll find a way.
