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 (cosmos/cosmos-sdk#5803) and Gaia (cosmos/gaia#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.

is it okay to close this PR? |

Sure. We’re going to have to update Gaia at some point, but it’s outdated and all kinds of broken so I’ll submit a new one when appropriate. |

Description
Adds support for state snapshots, based on cosmos/cosmos-sdk#5803.
Would appreciate suggestions for improvements here, primarily how to avoid panics for errors, and if it might be possible to do this setup automagically in the Cosmos SDK (main problem: supplying the home directory path to the base app without changing
AppCreator).For contributor use:
