* Reformulate random seed to be more random

- First 80 random values come from cycling the incomplete series (
  instead of filling with zeroes)
- Calculate random material each usage (use a single amalgamated
  ring buffer to store them for avoiding 81 lookups each time)
- Mutate inputs by hashing each with:
  - its index (into the 81)
  - an additional "subject" key provided by caller

This keeps the final output low-influence while still allowing
it to be used as the seed to independent contexts. (Hashing the
result to give the final seed is no better than using parent_hash).

* 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.
