  1. Change apply_batch to take argument by-reference. 

    This change facilitates that you can setup a batch and then execute it
inside of a transaction. For example:

```rust
let db = config.open().unwrap();
let t1 = db.open_tree(b"1")?;

let mut b1 = Batch::default();
b1.insert(b"k1", b"v1");
b1.insert(b"k2", b"v2");

t1.transaction(|tree| {
    tree.apply_batch(&b1)?;
    Ok(())
})?;
```
