* Add a new host function for reporting fatal errors * Fix one of the wasmtime executor tests * Have `#[runtime_interface(wasm_only)]` actually mean WASM-only, and not no_std-only * Print out errors through `Display` instead of `Debug` * Switch one more trait to require `Error` for its error instead of only `Debug` * Align to review comments
