* Add simple benchmark for the runtime api * Make the executor support native calls * Some documentation * Hide behind `feature = "std"` * Rework the native calls * Make all tests compile again * Make every parameter using the Block serialized/deserialized in the native call * Forward `UnwindSafe` requirement * Remove debug stuff * Add some documentation * Fixes warnings * Fixes errors after master rebase * Fixes compilation after master rebase * Fixes compilation after rebase
