* Adds `author_rotateKeys` RPC
`author_rotateKeys` will rotate all session keys, store them into the
keystore and returns their encoded public keys as result. These encoded
public keys can be used directly to send the transaction to the chain.

* Introduce inherent digests
* Implement inherent digests
* fix silly error
* 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.
* Remove bogus assertion
* Fix testsuite compilation
* Remove unused import
* Fix compiler diagnostics

This enforces that inherent digests are added first.

* Try to fix the storage error

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

* Remove unnecessary filtering of BABE pre-digests
We no longer get duplicate BABE pre-digests, so if they appear, the

* 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

assertion.
* Don’t compute storage root until storage changes are done.
Also, fix a compilation error.

* Fix accidental build bustage
* Trying to get the tests to work
* Add logging messages and remove dead code
There seems to be a problem with the test network. Since AuRa and BABE
are both affected, this is most likely due to the switch from ed25519 to
sr25519.
* Trying to get the tests to work
* Add logging messages and remove dead code
There seems to be a problem with the test network. Since AuRa and BABE
are both affected, this is most likely due to the switch from ed25519 to
sr25519.
* 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
* Change expected JSON string
The test was also broken on `master`, so I suspect that the test was
incorrect.
* Responded to review
* Remove hard-coded threshold from production code
A hard-coded threshold is now only used in tests.

* Rework how a runtime api calls into the runtime
Now we generate a default implementation for each api call that calls
