evidence: modify evidence types (#5342)

light: detect light client attacks (#5344)

evidence: refactor evidence pool (#5345)

abci: application evidence prepared by evidence pool (#5354)

## Description

This PR aims to make the crypto.PubKey interface more intuitive. 

Changes: 

- `VerfiyBytes` -> `VerifySignature`

Before `Bytes()` was amino encoded, now since it is the byte representation should we get rid of it entirely?

EDIT: decided to keep `Bytes()` as it is useful if you are using the interface instead of the concrete key

Closes: #XXX

* fix usage of time in abci evidence

* update changelong and upgrading

* add test cases

this pr brings over the removal of pubkey from duplicatevote evidence from proto-breakage

ref #4580

- replaced format command
- added goimports to format command
- ran goimports

Fixes #3444

See https://github.com/tendermint/tendermint/pull/3403/files#r266208947

In #3403 we unexposed BlockTimeIota from the ABCI, but it's still part
of the ConsensusParams struct, so we have to remember to add it back
after calling PB2TM.ConsensusParams. Instead, PB2TM.ConsensusParams
should take it as an argument

Fixes #3432

Also

- init substructures to avoid panic in pb2tm.ConsensusParams
Before: if csp.Block is nil and we later try to access/write to it,
we'll panic.
After: if csp.Block is nil and we later try to access/write to it,
there'll be no panic.

As per conversation here: https://github.com/tendermint/tendermint/pull/3218#discussion_r251364041

This is the result of running the following code on the repo:

```bash
find . -name '*.go' | grep -v 'vendor/' | xargs -n 1 goimports -w
```

privval: remove GetAddress(), memoize pubkey

* Add ValidatorPubkeyTypes as a consensus param

Ref #2414

* update spec

* address anton's comment

* Switch to Validator and Validator Params

* Correct changelog entry

* Address bucky's comments!

* forgot to update changelog

* fix typo

* fix Params naming

* 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

Refs #2035

* libs: Remove usage of custom Fmt, in favor of fmt.Sprintf

Closes #2193

* Fix bug that was masked by custom Fmt!

Signatures are now []byte, which saves on the number of bytes after
amino encoding

(squash this) address Ismail's comment

Refs #1134

Validation:

- ignored in block.ValidateBasic since it's stateful information
- checked in blockExec.ValidateBlock

* change validators to last_commit_info in RequestBeginBlock
* do not send pubkeys with RequestBeginBlock

Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.
