new lint: passing 0 as length to Vec::resize

[sugar700]

Clippy should inform about passing 0 as length to resize. It's not useful, and it's likely a mistake caused by swapping the parameter order.

Example code:

fn main() {
    let mut v = Vec::new();
    v.resize(0, 1024);
}

I can implement this.

Are you still working on this, @JarredAllen? Otherwise, I could have a go at it.

I had said I would do this thinking that the other issue I was working on would wrap up quickly, but then it turned out that there was more to do (and I now also have to deal with finals). If you want to handle this, feel free to do so.

@mlegner are you still active on this one?

[mlegner]

@montrivo I'm sorry, I completely forgot about this issue. 😞
No, I'm currently not working on it and won't have time in the next few days. So, if you're interested, go ahead.

Thanks for the quick answer. I'll take a look at it.
