This change allows aliases: type Foo = bindgen::Bar; and C++ opaque types: type Foo; to declare that they're 'trivial' in the sense that: * They have trivial move constructors * They have no destructors and therefore may be passed and owned by value in Rust. A subsequent commit will add C++ static assertions. This commit is a BREAKING CHANGE as it requires existing ExternTypes to gain a new associated type

I've just read #308 and it looks like I should rebase on top of that, if you think it will land soon, as there's a lot of commonality. I also need to add some tests like that PR has done. |

Fixes #313.
This is a breaking change as it requires all implementers of
ExternTypeto add another associated type. Defaults for associated types are an unstable feature, the compiler tells me. Perhaps we should avoid this by using a new trait,ExternTypeKind, instead.
