* Fix and simplify the BABE runtime
The BABE runtime was massively overcomplicated and also wrong. It
assumed it needed to:
1. delay new authorities taking effect until the next epoch
2. not delay emitting `Consensus` digests to mark epoch changes
However, the first is handled by the `srml_session` crate, and the
second is flat-out incorrect: `Consensus` digests take effect
immediately. Furthermore, `srml_babe` tried to duplicate the
functionality of `srml_session::PeriodicSession`, but did it both
clumsily and incorrectly. Fortunately, the new code is simpler and far
more likely to be correct.
* Use `system` to get the test authorities
The genesis block used by tests defines no authorities. Only the test
suite is affected.
* Fix test runtime impl for BabeApi::epoch() with std
* Fix compilation
* Cached authorities are in the form of an epoch
not a `Vec<AuthorityId>`.
* `slots_per_epoch` is not fixed in general
The BABE code previously assumed `slots_per_epoch` to be a constant,
but that assumption is false in general. Furthermore, removing this
assumption also allows a lot of code to go away.
* fix compile error
* Implement epoch checker
* Fix runtime compilation
* fork-tree: add method for finding a node in the tree
* babe: register epoch transitions in fork tree and validate them
* fork-tree: add method for arbitrary pruning

BABE needs to know not only what the current validator set is, but also
what the next validator set will be. Expose this to clients of the
session module.

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

* Implementation of inherent digests in BABE
All tests pass. There are still limitations:
1. The runtime strips out inherent digests, so BABE must re-add them.
2. The test runtime checks that it can re-compute all digests. It
can’t, so I had to comment out that test.
* Fix compilation and seal import
Seals were not imported correctly: the pre-digest was imported twice,
instead of both it and the seal being imported. Also, other parts of

* Working testsuite at last!
The problem was with serialization and deserialization. Normally,
those functions are generated automatically, but those for `BabeSeal`
had to be written manually. The hand-written versions were not
correct, however, as shown by the decoder not being able to decode the
output of the encoder.
* Enable BabeSeal::Encode asserts in --release tests
* Bump runtime and dependency versions
* Fix wasm compilation
The wasm build was broken because of a typo in
`core/test-runtime/src/lib.rs`, and missing gates on the `std` feature
in `core/consensus/{aura,babe}/primitives/Cargo.toml`. Additionally,
improve the quotation in the build scripts.
* Merge Cargo.lock

The test was also broken on `master`, so I suspect that the test was
