Missing `extern crate arbitrary` error

[abonander]

The fuzz!() macro uses items from the arbitrary crate but does not declare extern crate arbitrary (it probably needs to be pub extern crate arbitrary for the macro to use it). The arbitrary crate should be added to this crate's dependencies and then imports from arbitrary can be prefixed by the $crate metavar (references to honggfuzz should be replaced with $crate as well or else if the user renames it with extern crate honggfuzz as ... then it will not be found).

Fixed fuzz!() macro:

macro_rules! fuzz {
    (|$buf:ident| $body:block) => {
        $crate::fuzz(|$buf| $body);
    };
    (|$buf:ident: &[u8]| $body:block) => {
        $crate::fuzz(|$buf| $body);
    };
    (|$buf:ident: $dty: ty| $body:block) => {
        $crate::fuzz(|$buf| {
            let $buf: $dty = {
                use $crate::arbitrary::{Arbitrary, RingBuffer};
                if let Ok(d) = RingBuffer::new($buf, $buf.len()).and_then(|mut b|{
                        Arbitrary::arbitrary(&mut b).map_err(|_| "")
                    }) {
                    d
                } else {
                    return
                }
            };

            $body
        });
    };
}

This and compatibility with version 0.2 of arbitrary is resolved by #15
