Merge #99 
99: Revive Float+Real in no_std thanks to libm r=cuviper a=yoanlcq

Greetings,

This is a hopeful fix for #75.  
Basically: Add `libm` as an optional dependency, and handle three possible cases depending on which features are enabled:
- std and libm: std is used;
- std and not libm: std is used;
- libm and not std: libm and FloatCore are used.

It was briefly mentioned that `libm` wasn't ready yet, but this was months ago, and I believe it is better not to wait for too long.  
If anything, bugs in `libm` should be fixed in `libm`; `num-traits` is only delegating its implementations to it; not to mention that the more `libm` is used, the likelier issues are to be found and hopefully fixed.

Thanks in advance!

104: Add inplace methods to `Zero` and `One` r=cuviper a=lcnr

Adds the following default implemented methods to `Zero` and `One`:

```rust
fn set_zero(&mut self) {
    *self = Zero::zero();
}
```

```rust
fn set_one(&mut self) {
    *self = One::one();
}
```

This allows for reuse of BigNums.

Samuel Tardieu fc4f1afdf6 Fix CheckedShl/CheckedShr documentation 
Fix #57 and more:

- CheckedShl was hinting that None was returned on overflow rather than
  on too large a rhs.
- Ditto for CheckedShr.
- CheckedShr documentation erroneously indicated that a left shift was
  going to be performed instead of a right shift.

73: Avoid `as` casts in default FromPrimitive methods r=cuviper a=cuviper

Particularly, the default `from_f64` used `n as i64`, which has
undefined behavior on overflow, kind of defeating the purpose here.
Now we use a checked `to_i64()` for this, and even try `to_u64()` as a
fallback for completeness.

Also make similar changes to default `ToPrimitive`, but at least it
didn't have the same casting problem.
