4905640e9b types: CommitVotes struct as last step towards #1648 (#3298)
* VoteSignBytes builds CanonicalVote

* CommitVotes implements VoteSetReader

- new CommitVotes struct holds both the Commit and the ValidatorSet and
  implements VoteSetReader
- ToVote takes a ValidatorSet

* fix TestCommit

* use CommitSig.BlockID

Commits may include votes for a different BlockID, could be nil,
or different altogether. This means we can't use `commit.BlockID`
for reconstructing the sign bytes, since up to -1/3 of the commits
might be for independent BlockIDs. This means CommitSig will need to
include an indicator for what BlockID it signed - if it's not the
committed one or nil, it will need to include it fully in order to be
verified. This is unfortunate but unavoidable so long as we include
votes for non-committed BlockIDs (which we do to track validator
liveness)

* fixes from review

* remove CommitVotes. CommitSig contains address

* remove commit.canonicalVote method

* toVote -> getVote, takes valIdx

* update adr-025

* commit.ToVoteSet -> CommitToVoteSet

* add test

* fix from review

b089587b42 make gosec linter pass (#3294)
* not related to linter: remove obsolete constants:
 - `Insecure` and `Secure` and type `Security` are not used anywhere

* not related to linter: update example

 - NewInsecure was deleted; change example to NewRemoteDB

* address: Binds to all network interfaces (gosec):

 - bind to localhost instead of 0.0.0.0
 - regenerate test key and cert for this purpose (was valid for ::) and
 otherwise we would see:
 transport: authentication handshake failed: x509: certificate is
 valid for ::, not 127.0.0.1\"

(used https://github.com/google/keytransparency/blob/master/scripts/gen_server_keys.sh
to regenerate certs)

* use sha256 in tests instead of md5; time difference is negligible

* nolint usage of math/rand in test and add comment on its import

 - crypto/rand is slower and we do not need sth more secure in tests

* enable linter in circle-ci

* another nolint math/rand in test

* replace another occurrence of md5

* consistent comment about importing math/rand

Introduce CommitSig alias for Vote in Commit (#3245)
* types: memoize height/round in commit instead of first vote

* types: commit.ValidateBasic in VerifyCommit

* types: new CommitSig alias for Vote

In preparation for reducing the redundancy in Commits, we introduce the
CommitSig as an alias for Vote. This is non-breaking on the protocol,
and minor breaking on the Go API, as Commit now contains a list of
CommitSig instead of Vote.

* remove dependence on ToVote

* update some comments

* fix tests

* fix tests

8888595b94 [R4R] Fixed sized and reordered fields for Vote/Proposal/Heartbeat SignBytes (#2598)
* 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

e1538bf67e state: require block.Time of the fist block to be genesis time (#2594)
* 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)
