Replaces generic-array with hybrid-array, which is built on a combination of typenum and const generics, providing a degree of interoperability between the two systems.

hybrid-array is designed to be a largely drop-in replacement, and the number of changes required to switch are relatively minimal aside from some idiosyncracies.

Looks good, but it would be nice to see migration of the other trait crates as well to be safe against potential unforeseen issues.

Since block-buffer depends on crypto-common, I've opened the next step of this migration in the utils repo: RustCrypto/utils#944

generic-array v1.0 has implemented Try/From for arrays using const generics and simplified the ArrayLength trait. Is this PR still relevant in the light of it?

Yes, hybrid-array is natively built on const generic arrays at its core. Array is a newtype of the inner array type, which is pub.

generic-array instead has an opaque inner type and uses large amounts of unsafe code to achieve its goals. It has wrappers to use const generics which use a similar technique to hybrid-array (and thus have similar limitations), but if you use that approach like hybrid-array has done you can go all-in and get rid of (most of) the unsafe code.

Ok. Should we migrate to generic-array v1.0 in the next release cycle first or would you prefer to try hybrid-array migration without it?

Personally I'd prefer to go straight to hybrid-array and have already done some of the work, see also RustCrypto/utils#944

I can do cipher and digest next.

The minimal-versions failure seems to be a nightly regression and probably impacts master as well

Can you also change bound for the BlockSize sealed impl from Self: IsLess<U256> + IsGreater<U1> to Self: IsLess<U256> + IsGreater<U0>? I intended to do it in #1174.
