Previously you could not assume that your transaction hash would
appear on chain.

consensus: Fix test for blocks with evidence

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

Merge 0.23.8 back into develop

This now makes bit array functions which take in a second bit array, thread
safe. Previously there was a warning on bitarray.Update to be lock the
second parameter externally if thread safety wasrequired.
This was not done within the codebase, so it was fine to change here.

Closes #2080

Hotfix/0.22.7

* .github: Split the issue template into two seperate templates

Now we have different bug report and feature request templates.

* Forgot to add the name, and about fields

secret connection update

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)

hkdfchachapoly was a construction we came up with. There is no longer any
reason to use it. We should instead just use xchacha for the remaining use
cases we have. (Symmetrically encrypting the keys in the sdk keys package)

* crypto: Add benchmarking code for signature schemes

This does a slight refactor for the key generation code. It now calls a
seperate unexported method to allow generation from a reader. I think this
will actually reduce time in generation, due to no longer initializing an
extra slice. This was needed in order to enable benchmarking.

This uses an internal package for the benchmarking code, so that this can
be standardized without being exported in the public API. The benchmarking
code is derived from agl/ed25519's benchmarking code, and has copied the
license over.

Closes #1984

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.

Hotfix/v0.22.6

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

Refs #1861

We don't use the fee field and its likely just confusing.

We can add backwards compatible priority (instead of fee) later.

Note priority is better than fee because it lets the app do the math on how to rank order transactions, rather than forcing that into tendermint (ie. if we return fee, priority would be fee/gas)
