Homu 8b5d4ac24e Auto merge of #296 - vks:no_std, r=cuviper
traits: Introduce std feature

This makes it possible to build `traits` without `std`. For this a new
trait `BasicFloat` was introduced, implementing some basic functionality
that works with `core`. Most notably this is lacking functions like
`cos`, `sin`, etc.

`Float` is not available without `std`.

Homu ef752e4687 Auto merge of #291 - cuviper:hasher, r=cuviper
Get the default hasher indirectly

`DefaultHasher` wasn't stable until 1.13, at which point all the other
hashers were deprecated, so it's not easy for us to name a hasher type to
use for testing.  However, `RandomState` has been stable since 1.7, and it
implements `BuildHasher` that has a `Hasher` associated type.

Add new traits for reference and assignment operators

There are two new "utility" traits covering the basic operators:
`Add`, `Sub`, `Mul`, `Div`, and `Rem`.

- `NumOps<Rhs, Output>`: operators with an arbitrary operand and output.
- `NumAssignOps<Rhs>`: assignment operators with an arbitrary operand.

Then the new collection of numeric traits are:

- `Num`: effectively unchanged, just taking operands by value.
- `NumRef`: `Num` adding reference operands on the right side.
- `RefNum`: `&T` operators, with either `T` or `&T` on the right side.
  - This does not specify `T: Num`, as rust-lang/rust#20671 means that
    could only add a constraint, without implying its presence for use.
- `NumAssign`: `Num` adding assignment operators by value.
- `NumAssignRef`: `NumAssign` adding reference assignment operators.
  - Nothing actually implements this yet!

Acknowledgement: this is roughly based on [@andersk's suggestion](https://github.com/rust-num/num/issues/94#issuecomment-269073071).

Homu ef08fe2f96 Auto merge of #286 - yoanlcq:missing-impls-for-wrapping, r=cuviper
impl remaining num-traits for std::num::Wrapping<T>

This is a (late) follow-up for [https://github.com/rust-num/num/pull/279](https://github.com/rust-num/num/pull/279) since I realized that implementing `Num` for `Wrapping<T>` was merely half of the work.

This PR makes `Wrapping<T>` implement the remaining appropriate traits, granting it the ability to really be used a complete substitute for its primitive integer counterparts.
Some benefits are :
- Less refactoring for users using `num`'s traits replacing some primitives by their `Wrapping` counterpart (same for the opposite);
- Since `Wrapping<T>` is from `std`, nobody except us can `impl` our traits for it, so people don't have to create their own.
