This PR lays the foundation for implementing the archive RPC methods. The methods implemented by this PR: - archive_unstable_body: Fetch the block's body (a vector of hex-encoded scale-encoded extrinsics) from a given block hash - archive_unstable_genesisHash: Fetch the genesis hash - archive_unstable_header: Fetch the header from a given block hash Added unit tests for the methods. This PR is implementing the methods without exposing them to the RPC layer; which are to be exposed by a follow-up PR.

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.
