This is largely a cherry pick of #6755 with some additional fixups added where detected.
This change moves the blockchain package to a package called blocksync. Additionally, it renames the relevant uses of the term `fastsync` to `blocksync`.

Fixes#828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).
This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704.
* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.
* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.
* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.
* Added BlockStore.DeleteBlock()
* Added initial block pruner prototype
* wip
* Added BlockStore.PruneBlocks()
* Added consensus setting for block pruning
* Added BlockStore base
* Error on replay if base does not have blocks
* Handle missing blocks when sending VoteSetMaj23Message
* Error message tweak
* Properly update blockstore state
* Error message fix again
* blockchain: ignore peer missing blocks

* Added test for block replay with truncated history
* Handle peer base in blockchain reactor
* Improved replay error handling
* Added tests for Store.PruneBlocks()

* Updated changelog
* Fix tests
* Appease linter
* Minor review fixes
* Non-empty BlockStores should always have base > 0
* Update code to assume base > 0 invariant
* Added blockstore tests for pruning to 0
* Make sure we don't prune below the current base
* Added BlockStore.Size()
* config: added retain_blocks recommendations
* Update v1 blockchain reactor to handle blockstore base

Why:
- native type provides better guarantees than ", in ms" comment (harder
to shoot yourself in the leg)
- flexibility: you can change units
