381: Hook up error propagation r=lachlansneff a=lachlansneff

You can now retrieve the error from a panicking or error-returning imported function.

Example:

```rust
#[derive(Debug)]
struct ExitCode {
    code: i32,
}

fn do_panic(_ctx: &mut Ctx) -> Result<i32, ExitCode> {
    Err(ExitCode { code: 42 })
}

// This wasm functions calls `do_panic`.
let foo: Func<(), i32> = instance.func(...)?;

let result = foo.call();

println!("result: {:?}", result);

if let Err(RuntimeError::Error { data }) = result {
    if let Ok(exit_code) = data.downcast::<ExitCode>() {
        println!("exit code: {:?}", exit_code);
    }
}
```

outputs:

```
result: Err(unknown error)
exit code: ExitCode { code: 42 }
```

370: Fix WASI by using u32 everywhere instead of u16 r=syrusakbary a=syrusakbary

Long story short: we were seeing some undeterministic behavior when running wasmer with WASI on Linux.

It turned out we are doing some bad conversions from u16 to the inner type in the trampolines (or func type?), and this only showed up in certain systems.

This PR is a quick fix to get things running quickly, but we will proceed with a proper fix soon and revert this PR.

Note: the discovery of the bug was done by @bjfish, and this PR is just a very simple way to address it.
