This condition is really hard to get. Initially, lockedRound and
validRound are set to -1 as we start with round 0.

Refs #2702

* catch up with amino changes in
https://github.com/tendermint/go-amino/pull/222

* WIP: update to amino v0.13.0

* update to fixed amino release

* types: test tm2pm on fully populated header

* upgrade for amino v0.13.0-rc0

* fix lint

* comment out final test

* use types.NewValidator

* node: set p2p.ProtocolVersion from state, not globals

* types: first field in Canonical structs is Type

* fix spec

* types: dont use SimpleHashFromMap for header. closes #1841

* changelog and spec

* comments

* types: add Version to Header

* abci: add Version to Header

* state: add Version to State

* node: check software and state protocol versions match

* update changelog

* docs/spec: update for versions

* state: more tests

* remove TODOs

* remove empty test

This is a performance regression, but will also spare the types directory
from knowing about RFC 6962, which is a more correct abstraction. For txs
this performance hit will be fixed soon with #2603. For evidence, the
performance impact is negligible due to it being capped at a small number.

* Hash() uses tmhash instead of merkle.SimpleHashFromMap

* marshal whole struct

* update comments

* update docs

* WIP: switching to fixed offsets for SignBytes

* add version field to sign bytes and update order

* more comments on test-cases and add a tc with a chainID

* remove amino:"write_empty" tag

- it doesn't affect if default fixed size fields ((u)int64) are
written or not
- add comment about int->int64 casting

* update CHANGELOG_PENDING

* update documentation

* add back link to issue #1622 in documentation

* remove JSON tags and add (failing test-case)

* fix failing test

* update test-vectors due to added `Type` field

* change Type field from string to byte and add new type alias

- SignedMsgType replaces VoteTypePrevote, VoteTypePrecommit and adds new
ProposalType to separate votes from proposal when signed

- update test-vectors

* fix remains from rebasing

* use SignMessageType instead of byte everywhere

* fixes from review

* require block.Time of the fist block to be genesis time

Refs #2587:

```
We only start validating block.Time when Height > 1, because there is no
commit to compute the median timestamp from for the first block. This
means a faulty proposer could make the first block with whatever time
they want.

Instead, we should require the timestamp of block 1 to match the genesis
time.

I discovered this while refactoring the ValidateBlock tests to be
table-driven while working on tests for #2560.
```

* do not accept blocks with negative height

* update changelog and spec

* nanos precision for test genesis time

* Fix failing test (#2607)

This is just to match the style of the rest of the codebase, and to
reduce the number of files in types.

* crypto/merkle: Remove byter in favor of plain byte slices

This PR is fully backwards compatible in terms of function output!
(The Go API differs though) The only test case changes was to refactor
it to be table driven.

* Update godocs per review comments

* cap evidence in block validation

* state: use table-driven test for ValidateBlockHeader

* state: test evidence cap

* fixes from review

Closes #2525
