Bump dependencies

[kpcyrd]

This bumps rand and quickcheck to the latest version. We're about to ship num-bigint with this patch applied.

The code looks correct. I've also been playing with this locally, and we might want to tweak what rand features are pulled in, especially where they're only for dev-deps, but this is a minor point.

However, this is breaking change, since these are public dependencies -- you're changing public trait implementations to semver-incompatible versions.

We're about to ship num-bigint with this patch applied.

Who is "we"? Are you shipping this as an internal detail, or is it something that will be publicly visible and different than the crates.io num-bigint?

[kpcyrd]

oops, didn't pay enough attention when writing the text, "we" is referring to the debian rust team, the crate is used when building packages that depend on num-bigint. semver-incompatible reexports aren't much of a problem in that case.

I took the liberty of rebasing this and stacking some more changes on top. The MSRV is now 1.31, and 128-bit integer support is assumed. MSRV with rand, quickcheck, and no_std are all higher, respectively 1.32, 1.34, and 1.36. We now support rand on no_std too, and I moved some of the rand and quickcheck tests to sub-crates to avoid "polluting" the main dependencies. I want to do a Rust 2018 conversion too, but I'll do that separately.

Thanks!
