This reverts commit af53d7624752a744320e9cbb25749fdd8e6f46d2.
* `BabeSealSignature` → `BabeSeal`
* Move slot code to its own crate
This was highly non-trivial, due to cyclic dependencies.
* Remove redundancy between AuRa and BABE
Some of the code duplication was removed using a macro.
* Fix build error
* Avoid non-`#[doc(hidden)]` re-exports
Also, bump some library versions in `Cargo.toml`.
* Remove dead code in AuRa
* Remove impl_slot macro
It was more trouble than it was worth.
Also, delete useless dependencies on Serde.
* AuRa and BABE need different DB keys
* Bring back `aura::Network`, but deprecate it.
* Improve docs and add `slot_duration` inherent method
* Add docs to `substrate_consensus_aura::SlotDuration`
* Add missing documentation and #![forbid(missing_docs, unsafe_code)]
* Add a #![forbid(missing_docs)]
* Remove dependency of `test-runtime` on `slots`
* Update core/consensus/babe/src/lib.rs

* Remove wrongly added file
* Fix copyright notice
Co-Authored-By: DemiMarie-parity <48690212+DemiMarie-parity@users.noreply.github.com>
* Bump `impl_version` and `spec_version`
* Add more code to BABE
Most of it is copied from AuRa code, but at least the initial core is
there.
* Stuck on horrible compiler error message
* add missing files
* Spaces → tabs
* Simplify code
* Fix compilation
This involved fixing dependencies and adding a `Mutex`.
* More work on BABE
* Fix deprecation version

* The import queue code compiles, though it probably doesn’t work.
* Add VRF verification
* Update Cargo.lock
* Update dependencies
* Move test network to sr25519 authority keys
* 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.

* Fix wasm build + full example build
this requires parity codec implements codec for core::marker::PhantomData
* patch parity-codec link to github branch
* improve internal names and fix instance prefix
* Fix in macros
* add test modules for support
this allow to test for construct_runtime as well.
The reason to have put that in another crate is:
* if we put test in `tests/` dir of srml/support then decl_storage fails to get
srml-support access because it believes it is inside srml-support
crate and so derive access to `quote!{ crate }` but this is wrong
(and I don't see any way to prevent that, and it only bother us so I
don't think that matters that much)
* if we put test inside lib.rs then contruct_runtime cannot be used
because it call some macros that are defined with macros
(decl_outer_event and decl_outer_origin) and thus rustc complains.
* defaultinstance to its own struct to avoid errors
* enforce <T, I> for Event and Config, impl test
* add origin, log, inherent to test
* test more code generation
* basic storage test
* fix typo
* rename a few imports and field
* delete wip test in example and runtime
* change default prefix to make it backward compatible with test
* rename Instance to I and Instantiable to Instance
note: the name of generic parameter I is only enforce by decl_module!
and this could be rewritten

Went through the TODOs, removed a bunch, which are outdated or nothing more than a regular comment, documented a bunch more as actual tickets and made them FIXMEs and unified their structure (`FIXME #TICKETNO DESC` for local tickets, `FIXME: DESC LINK` for external tickets) for easier in-editor support. Further more remove unnecessary remarks and related old code that I noticed in that instance.
