[Ironruby-core] IronRuby FFI

That's something I'm curious about too. I don't know whether or not P/Invoke
alone can match the functionality of libffi. I'd have to look through some
of libffi and see if there's anything can't be accomplished in C#.

If everything can be accomplished in C#, I'd go that route. We could emit
types at runtime that have the necessary DLLImport attributes and such
(something I've already done for little projects of mine).
