* 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.
* Implement a basic randomness generating function
It just XORs the VRF outputs together.
* Actually implement on-chain randomness
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
* Document security guarantees of BABE randomness
* Add a `RandomnessBeacon` trait
* Document `RandomnessBeacon::random`
* Fix silly compile error (unexpected type arguments)
* Fix BABE randomness
* Implement `FindAuthor` for `babe::Module`
* Apply suggestions from code review

* Respond to suggestions from code review and fix bugs
* Store an authority index, not the authority itself.
* Avoid unnecessary decoding.
* Implement relative slots and BABE randomness fully and correctly.
* Remove spurious dependency
* Fix error reported by rust-analyzer
* Update Cargo.lock files
* `wrapping_add` → `checked_add`
The epoch index will not overflow. Panic if it does.
* Move randomness documentation to trait
* Fix compile error in test suite
* Explain 2^64 limit
