313: Scalar operations across all integer types r=cuviper

With my apologies for opening a new PR, and also for the 8 month delay, this continues the work started in #237 - the discussion there outlines the goals I was aiming for. I suppose this supersedes that PR and the other one can now be closed.

This PR adds support for Add, Sub, Mul, Div and Rem operations involving one BigInt/BigUint and one primitive integer, with operands in either order, and any combination of owned/borrowed arguments.

314: Derive ToPrimitive for enums r=cuviper

I had to double the compile fail tests, as they will bail on the first error.

I have some ideas for more complex to/from primitive derives (with inner values that implement to/from primitive), but I'll save those for a future PR.

318: Add cargo keywords and categories. r=cuviper

Fixes #306. Suggestions welcome for better keywords/categories, though there is a limit of 5 of each.

311: rational: make sure Hash agrees with Eq r=cuviper

We can't use a derived `Hash` when we have a manual `Eq`, because we
need to uphold the invariant `a == b` → `h(a) == h(b)`.  Since `Eq`
doesn't require them to be in reduced form, `Hash` also needs to be
normalized.

Fixes #310.

315: Fix float NaN positive/negative assumptions r=cuviper

These are the minimal assumptions to make about `NaN`. Fixes part of #312 (but not the `next` branch).

Eduardo Pinho 61cfdc37b3 BigInt two's complement adjustments
- rename `_twos_complement_` methods to just `_signed_`
- make `from_` variants take &[u8]
- refactor helper functions twos_complement (they take byte slice but use a generic function underneath)
- fix issues in `to_signed_` functions (only two's complement negative numbers; perform byte extension where needed)
- add tests to `to_signed_` methods
