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.
Followup from #4588. Allow the first `SaveBlock()` call in an empty block store to be at any height, to start from a truncated block history. Subsequent `SaveBlock()` calls must be for contiguous blocks.

* more work towards error handling
* error and emtpy bytes handling
* work on tests
* add changelog entry, change some error handling
* address some pr comments
* panic in a few more places
* move error higher up
* redo some error handling
* fix some bz == nil to len(bz) == 0
* change statebytes
* types: change `Commit` to consist of just signatures
These are final changes towards removing votes from commit and leaving
only signatures (see ADR-25)
Fixes#1648
* bring back TestCommitToVoteSetWithVotesForAnotherBlockOrNilBlock
+ add absent flag to Vote to indicate that it's for another block
* encode nil votes as CommitSig with BlockIDFlagAbsent
+ make Commit#Precommits array of non-pointers
because precommit will never be nil
* add NewCommitSigAbsent and Absent() funcs
* uncomment validation in CommitSig#ValidateBasic
* add comments to ValidatorSet funcs
* add a changelog entry
* break instead of continue
continue does not make sense in these cases
* types: rename Commit#Precommits to Signatures

send errors (RemovePeer) from switch on a different channel than the
one receiving blocks
renamed channels

* fix issue in test from previous cleanup
* cleanup
* Added termination scenarios, tests and more cleanup
* small fixes to adr, comments and cleanup
* Fix bug in sendRequest()
If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.
While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.
* remove bpPeer's didTimeout field
* Use distinct err codes for peer timeout and FSM timeouts
