* Initial work on exposing pre-runtime digests

This provides the primitive API, as well as exposing it from BABE.

* Initial work on using pre-digests in runtimes

This includes both code to expose them from `srml_system`, as well as
using it in (currently dead) code in `srml_babe`.

* Bump `{spec,impl}_version`

* Add `u64_backend` feature to curve25519-dalek

Otherwise, it errors out at compile-time.

* Bump `Cargo.lock`

* Do not depend on the schnorrkel crate in the runtime

The schnorrkel crate does not work on `#![no_std]`, but the runtime only
needs constants from it.  This adds our own definitions of those
constants, and checks them for correctness at compile-time.

* Actually implement storage of VRF outputs

* Trivial formatting change

* Provide a `hash_randomness` function in BABE

for processing VRF outputs.

It just XORs the VRF outputs together.

Blake2b is used for hashing.

* Update dependencies

* Run `cargo update` where needed

* Re-add a newline at EOF

* Remove broken and unsafe code

XOR is not a hash function, and must not be used as such.  The
implementation was also needlessly unsafe.

* Run `cargo update` where needed

* Remove spurious dependency

* Add a `RandomnessBeacon` trait

* Document `RandomnessBeacon::random`

fix typo

* Fix DiscoveryBehaviour::poll.

The previous implementation regularly returned `NotReady` from `poll`
despite the inner Kademlia behaviour having events ready, thus letting
the `poll`ing be largely driven by the task wakeups from the Delay for
the next random Kademlia query, inducing major delays in consuming
the ready Kademlia events and thus slowing progress.

The discovery test now passes quickly, as expected.

* Ensure the Delay is polled right after reset.

For task wakeup.
