* Sync: Propagate block announcement data This pr adds a feature to the sync protocol to propagate the data that we received alongside a block announcement. This is done by adding a cache that caches the last X block announcement data where X is set to the number of `in_peers` (giving every peer the chance to send us a different block). This will be required by parachains to ensure that even peers who are not connected to a collator receive the data alongside the block announcement to properly validate it and request the block. * Review comment * Bring back the code and add new variant to ensure we don't insert block announce data when something wasn't checked * Also use out_peers

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.
