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.

* make BlockTimeIota a consensus parameter, not a locally configurable option

Refs #2920

* make TimeIota int64 ms

Refs #2920

* update Gopkg.toml

* fixes after Ethan's review

* fix TestRemoteSignerProposalSigningFailed

* update changelog

* Don't use pointer receivers for PubKeyMultisigThreshold

* test that showcases panic when PubKeyMultisigThreshold are used in sdk:

 - deserialization will fail in `readInfo` which tries to read a
 `crypto.PubKey` into a `localInfo` (called by
  cosmos-sdk/client/keys.GetKeyInfo)

* Update changelog

* Rename routeTable to nameTable, multisig key is no longer a pointer

* sed -i 's/PubKeyAminoRoute/PubKeyAminoName/g' `grep -lrw PubKeyAminoRoute .`

upon Jae's request

* AminoRoutes -> AminoNames

* sed -e 's/PrivKeyAminoRoute/PrivKeyAminoName/g'

* Update crypto/encoding/amino/amino.go

Now that Tendermint Amino will be compatible with proto3, the Header in ABCI
should exactly match the Tendermint header - they will then be encoded
identically in ABCI and in Tendermint Core.

Refs #265

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

Refs #1856

This PR changes ABCI time format from int64 (Unix seconds) to WKT (WellKnownType) google.protobuf.Timestamp.

Refs #1857

Reasons:

better precision
standard DT for proto

* update Gopkg.lock
* [makefile] remove extra grep
    - go list excludes vendor by default now
* proto3 timestamp
* [docs/abci-spec] note about serialisation format
* make time non-nullable

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.

NOTE we only updating for tmlibs and abci

uint64 is considered dangerous. the details will follow in a blog post.

InitChain is send from the ABCI to the Core node when the ABCI
app has no blocks stored.
