* 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

what the next validator set will be.  Expose this to clients of the
session module.

* 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
the code did not compile due to incomplete refactoring.

The key is to pass *only* the pre-runtime digests to the runtime.  The
others must be stripped out by `initialize_block`.

* Fix silly typo

* Fix another silly mistake

* Remove unnecessary filtering of BABE pre-digests

We no longer get duplicate BABE pre-digests, so if they appear, the
header should be rejected outright.

* Update Cargo.lock files

* Reformatting

* Fix silly typo in inherent digest code

Also, revert `error.rs` files that contained calls to the `error_chain!`
macro.

* Try to keep the runtime from stripping pre-digests

Currently runs into the “Storage root must match that calculated”
assertion.

* Don’t compute storage root until storage changes are done.
