Follow up from #3512

Specifically:

    cli.conn.Close() need not be under the mutex (#3512 (comment))
    call the reqRes callback after the resCb so they always happen in the same order (#3512)

Fixes #3513

Calling ensurePeers outside of ensurePeersRoutine can lead to nodes
disconnecting from us due to "sent next PEX request too soon" error.

Solution is to just dial addrs we got from src instead of calling
ensurePeers.

Refs #2093

Fixes #3338

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

* Update ABCI spec doc to include new CheckTx params

Fixes #3716

## 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

Fix fundemental BoltDB backend correctness issues.

BoltDB's accessors will return slices that are only valid for the
lifetime of the transaction.  This adds copies where required to prevent
hard to debug crashes (among other things).

`Delete` should queue a delete operation that targets the entire
database, and not just keys that happen to be in the current batch.
