Migrates the p2p connections to Protobuf. Supersedes #4800.
gogoproto's `NewDelimitedReader()` uses an internal buffer, which makes it unsuitable for reading individual messages from a shared reader (since any remaining data in the buffer will be discarded). We therefore add a new `protoio` package with an unbuffered `NewDelimitedReader()`. Additionally, the `NewDelimitedWriter()` returns the number of bytes written, and we've added `MarshalDelimited()` and `UnmarshalDelimited()`, to ease migration of existing code.
Attempt to fix this the below test failure by waiting for the listener to get ready. I am not at all convinced that this is the correct fix - the below indicates that the TCP socket was closed after it was set up - but I'm unable to come up with an actionable hypothesis for what caused it.

Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
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.
to prevent malicious nodes from sending us large messages (~21MB, which
is the default `RecvMessageCapacity`)
This allows us to remove unnecessary `maxMsgSize` check in `decodeMsg`. Since each channel has a msg capacity set to `maxMsgSize`, there's no need to check it again in `decodeMsg`.

Previously, many reactors were initialized with the name "Reactor," which made it difficult to log which reactor was doing what. This changes those reactors' names to something more descriptive.
* format: add format cmd & goimport repo
- replaced format command
- added goimports to format command
- ran goimports
