Koute 9a31b2c341 Add a new host function for reporting fatal errors; make WASM backtraces readable when printing out errors (#10741)
* Add a new host function for reporting fatal errors

* Fix one of the wasmtime executor tests

* Have `#[runtime_interface(wasm_only)]` actually mean WASM-only, and not no_std-only

* Print out errors through `Display` instead of `Debug`

* Switch one more trait to require `Error` for its error instead of only `Debug`

* Align to review comments

Aura (Authority-round) consensus in substrate.

Aura works by having a list of authorities A who are expected to roughly agree on the current time. Time is divided up into discrete slots of t seconds each. For each slot s, the author of that slot is A[s % |A|].

The author is allowed to issue one block but not more during that slot, and it will be built upon the longest valid chain that has been seen.

Blocks from future steps will be either deferred or rejected depending on how far in the future they are.

NOTE: Aura itself is designed to be generic over the crypto used.
