Merges literals into a static array. Plugin for compiler.

Use

1. Easy use

```

![feature(plugin)]

![plugin(cluConcatBytes)]

fn main() { let cstr = concatbytes!("cluWorld"); //&'static [u8] //array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8 asserteq!(cstr, b"cluWorld");

let c_str2 = concat_bytes!("clu", b"World");
//&'static [u8]
//array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8
assert_eq!(c_str2, b"cluWorld");

let c_str3 = concat_bytes!(
    b'c', b'l', b'u',
    b'W', b'o', b'r', b'l', b'd'
);
//&'static [u8]
//array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8
assert_eq!(c_str3, b"cluWorld");

let c_str4 = concat_bytes!(
    "clu", b'W', b'o', b'r', b'l', b"d"
);
//&'static [u8]
//array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8
assert_eq!(c_str4, b"cluWorld");

my_function(c_str);
my_function(c_str2);
my_function(c_str3);
my_function(c_str4);

}

fn my_function(array: &'static [u8]) { //'static --> it is possible not to write.

println!("array: {:?}, len: {}", array, array.len());

} ```

1. Raw use

```

![feature(plugin)]

![plugin(cluConcatBytes)]

fn main() { let cstr = concatbytes!(@"cluWorld"); //[u8; 8] //array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8 asserteq!(&cstr, b"cluWorld");

let c_str2 = concat_bytes!(@"cluWorld");
//[u8; 8]
//array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8
assert_eq!(&c_str2, b"cluWorld");


let c_str3 = concat_bytes!(@"clu", b"World");
//[u8; 8]
//array: [99, 108, 117, 87, 111, 114, 108, 100], len: 8
assert_eq!(&c_str3, b"cluWorld");

my_function(c_str);
my_function(c_str2);
my_function(c_str3);

}

fn my_function(array: [u8; 8]) { //'static --> it is possible not to write.

println!("array: {:?}, len: {}", array, array.len());

} ```
