* Update to use mutate

* Update to final ss58 spec

* Fix tests

* Rebuild

* Add `start_aura2`.

* .gitignore patch conflict files

and remove one that accidentally got committed

* Fix build

The tests still don’t work.

* Fix compilation errors

* Fix compile errors (again)

* Try (and fail) to fix tests

* Properly deserialize data

Previously, `DigestItem::Consensus` had no separate `DigestItemType`,
so it did not get properly serialized and deserialized.

* Add extra debug logging.  Always allow old seals.

A `RUST_LOG=substrate_aura_consensus cargo test --all -- --nocapture \
tests::authoring_blocks` revealed that old seals were being and
rejected, causing the test to hang.  As a temporary debug measure, allow
old seals unconditionally, so that CI can test if this fixes the
problem.

* Forcibly disable rejection of old seals

* Use old trait, but newer serialization

The old trait for `CompatibleDigestItem` actually worked.  By changing
its implementation, one can ensure that all *new* seals have the modern
form, but *legacy* seals are still decoded correctly.

* Bump impl version

* Squash spurious deprecation warning

`rustc` should not be emitting a deprecation warning in deprecated
code, but it does, so silence it.

* Rip out unused Cargo feature

* Move AURA to aura_primitives

* Respond to code review

* Wrap overly-long line

* Reduce logging verbosity and add target

* Add dependency on `sr-primitives` to `aura_primitives`

* Fix build

It failed with a message about Cargo.lock being out of date.

* core: aura: rename aura engine id const

* core: aura: remove superfluous logging

* core: primitives: add removed semicolons

* core: aura: remove unused import

* core: network: style fix

* runtime: update wasm blobs

* runtime: bump impl_version

* core: primitives: tag all DigestItemType variants explicitly

* Crypto fixes:

- Use schnorrkel's HDKD derive
- Assume all key URIs beginning with `/` are prefixed with public
  root phrase.

* Remove commented code.
