Generating non -sys crate

[jadahl]

Have you considered generating non -sys crate, i.e. wrapping the -sys crate calls inside unsafe { ... }? It'd make using the GIR libraries from Rust a lot more pleasent.

The crate grust-proof is the playground for how the safe non -sys crate output should look like.
It's two years old now, but I want to get back to moving it forward some day, and eventually produce templates for the generator.
