because
- they are locked in .lock file already
- individual dependencies can be updated with `dep ensure -update XXX`
- review process (and ^^^) should help us prevent accidental updates

Closes #2798

* Align Proposal message with spec

* Update spec

* reorder fields

* add TestVoteString & update tests

* remove redundant info from Proposal.String()

* WIP: update to amino 0.14.0

* update Changelog

* Update to latest amino version (v0.14.0)

* 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

* ed25519: use golang/x/crypto fork

* changelog

* gix GenerateFromPassword

* fixes from review

Why:
original fork is abandoned and not supported anymore.

Changes:
- LevelDB 1.19 (LevelDB and Snappy are both compiled and linked statically, so while you will not need them installed on your target machine, you should have a roughly compatible version of libstdc++.)
- snappy and lz4 libs included by default

* crypto/secp256k1: Fix signature malleability, adopt more efficient encoding

This removes signature malleability per ADR 14, and makes secp match
the encoding in ADR 15.

* (squash this) add lock

Refs #1916

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

Closes #2193

* Fix bug that was masked by custom Fmt!

* remove gogoproto from tools

because it's not a binary

* update protobuf version to 3.6.1 in `make get_protoc`

* update libs/common/types.pb.go and rpc/grpc/types.pb.go

* fix app tests

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

Closes #1944

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

This now uses one hkdf on the X25519 shared secret to create
a key for the sender and receiver.
The hkdf call is now just called upon the computed shared
secret, since the shared secret is a function of the pubkeys.

The nonces now start at 0, as we are using chacha as a stream
cipher, and the sender and receiver now have different keys.

Generate keys with HKDF instead of hash functions, which provides better security properties.

Add xchacha20poly1305 to secret connection. (Due to rebasing, this code has been removed)

This adds a new makefile command, which is used in CI linting, `make check_dep`.
This ensures the toml is in sync with the lock, and that were not pinning to a
branch in any repository.

This also adapts `make get_vendor_deps` to check the lock, in addition to
populating the vendor directory. This removes the need for `make ensure_deps`.

This makes `make get_vendor_deps` consistent between tendermint and the sdk.

- leave protobuf on 1.1.1 for grpc import fixes
- amino v0.11 breaks tendermint - revert to v0.10.1

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.

Closes #1956

gogoproto.nullable compatible with GRPC downstream of ABCI and libs
protbuf types

This reverts commit d02c5d1e30.

* tmbench: Make sendloop act in one second segments

Previous behaviour was to make the sendloop send all its messages
and then time how long that took. (Possibly waiting if too fast)
This has the same operation when too fast, but stops the loop
after one second. This is useful if a large tx amount is specified
and the ping doesn't get executed. Tmbench no longer crashes on
large rates.

* Update Readme

* Update tendermint to develop branch
* Update tmlibs to develop branch
* Add total field for txs and blocks
