Fixes #3986

This pull request is prefixing all the types in proto to avoid conflict.

When a go application is using Tendermint as a library and also define similar types in gogo proto some conflicts might occur (as types is a common package in go).

By prefixing the types with tendermint, this highly reduces the risk of conflicts.

BREAKING CHANGE.

This modification breaks the ABCI Application endpoint.

What was accessible before with `/types.ABCIApplication/Flush` is now accessible with `/tendermint.abci.types.ABCIApplication/Flush`.

ref #2790

As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states).

In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client.

And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure:

enum CheckTxType {
  New = 0;
  Recheck = 1;
}

message RequestCheckTx {
  bytes tx = 1;
  CheckTxType type = 2;
}

* Refactor ABCI CheckTx to notify of recheck

As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for:

1. a flag indicating whether a query is a recheck or not (and allows for
   possible future, more nuanced states)
2. an `additional_data` bytes array to provide information for those more
   nuanced states.

In order to pass this extended information through to the ABCI app, the
`proxy.AppConnMempool` (and, for consistency, the
`proxy.AppConnConsensus`) interface seems to need to be refactored.

* Fix linting issue

* Add CHANGELOG_PENDING entry

* Remove extraneous explicit initialization

## PR

This PR introduces a fundamental breaking change to the structure of ABCI response and tx tags and the way they're processed. Namely, the SDK can support more complex and aggregated events for distribution and slashing. In addition, block responses can include duplicate keys in events.

    Implement new Event type. An event has a type and a list of KV pairs (ie. list-of-lists). Typical events may look like:

"rewards": [{"amount": "5000uatom", "validator": "...", "recipient": "..."}]
"sender": [{"address": "...", "balance": "100uatom"}]

The events are indexed by {even.type}.{even.attribute[i].key}/.... In this case a client would subscribe or query for rewards.recipient='...'

    ABCI response types and related types now include Events []Event instead of Tags []cmn.KVPair.
    PubSub logic now publishes/matches against map[string][]string instead of map[string]string to support duplicate keys in response events (from #1385). A match is successful if the value is found in the slice of strings.

closes: #1859
closes: #2905

- 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.

should exactly match the Tendermint header - they will then be encoded
identically in ABCI and in Tendermint Core.

Reasons:

better precision
standard DT for proto

    - go list excludes vendor by default now
* proto3 timestamp
* [docs/abci-spec] note about serialisation format
* make time non-nullable

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)
