6cc7107aa6 Add Orderable trait 
This is a temporary trait until we have default methods. We don't want to encumber all implementors of Ord by requiring them to implement these functions, but at the same time we want to be able to take advantage of the speed of the specific numeric functions (like the `fmin` and `fmax` intrinsics).

6efbbf2e14 Combine PrimitiveInt, Int, and Uint traits into one single trait 
Having three traits for primitive ints/uints seemed rather excessive. If users wish to specify between them they can simply combine Int with either the Signed and Unsigned traits. For example: fn foo<T: Int + Signed>() { … }

6fa054df96 Use borrowed pointers for Integer methods 
This brings them in line with the quot and rem traits, and is be better for large Integer types like BigInt and BigUint because they don't need to be copied unnecessarily.

024bf2ec72 Rename Natural to Integer 
'Natural' normally means 'positive integer' in mathematics. It is therefore strange to implement it on signed integer types. 'Integer' is probably a better choice.

f39152e07b Implement Natural trait 
This adds the following methods to ints and uints:

- div
- modulo
- div_mod
- quot_rem
- gcd
- lcm
- divisible_by
- is_even
- is_odd

I have not implemented Natural for BigInt and BigUInt because they're a little over my head.

412a07055c auto merge of #5769 : gifnksm/rust/range_step, r=bstrie 
`uint::range_step` or `int::range_step` causes overflow or underflow as following.
code:
```rust
fn main() {
    for uint::range_step(3, 0, -2) |n| {
        println(fmt!("%u", n));
    }
}
```
output:

eb19462104 Converted libcore/uint-template.rs to the new string functions. 
- Moved ToStr implementation of unsigned integers to uint-template.rs.
- Marked the `str()` function as deprecated.
- Forwarded all conversion functions to `core::num::to_str_common()`
  and `core::num::from_str_common()`.
- Fixed most places in the codebase where `to_str()` is being used.
- Added uint-template to_str and from_str overflow tests.
