This PR prepares chains specs for _native-runtime-free_ world. This PR has following changes: - `substrate`: - adds support for: - JSON based `GenesisConfig` to `ChainSpec` allowing interaction with runtime `GenesisBuilder` API. - interacting with arbitrary runtime wasm blob to[ `chain-spec-builder`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/bin/utils/chain-spec-builder/src/lib.rs#L46) command line util, - removes [`code`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/frame/system/src/lib.rs#L660) from `system_pallet` - adds `code` to the `ChainSpec` - deprecates [`ChainSpec::from_genesis`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/client/chain-spec/src/chain_spec.rs#L263), but also changes the signature of this method extending it with `code` argument. [`ChainSpec::builder()`](https://github.com/paritytech/substrate/blob/20bee680ed098be7239cf7a6b804cd4de267983e/client/chain-spec/src/chain_spec.rs#L507) should be used instead. - `polkadot`: - all references to `RuntimeGenesisConfig` in `node/service` are removed, - all `(kusama|polkadot|versi|rococo|wococo)_(staging|dev)_genesis_config` functions now return the JSON patch for default runtime `GenesisConfig`, - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed, - `cumulus`: - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed, - _JSON_ patch configuration used instead of `RuntimeGenesisConfig struct` in all chain specs. --------- Co-authored-by: command-bot <> Co-authored-by: Javier Viola <javier@parity.io> Co-authored-by: Davide Galassi <davxy@datawok.net> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Kevin Krone <kevin@parity.io> Co-authored-by: Bastian Köcher <git@kchr.de>
Substrate
Substrate is a next-generation framework for blockchain innovation 🚀.
Getting Started
Head to docs.substrate.io and follow the installation
instructions. Then try out one of the tutorials. Refer to the Docker
instructions to quickly run Substrate, Substrate Node Template, Subkey, or to build a chain spec.

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
