## Issue:
This PR adds an "EXISTS" condition to the event query grammar. It enables querying for the occurrence of an event without having to provide a condition for one of its attributes.
As an example, someone interested in all slashing events might currently catch them with a query such as slash.power > 0.
With this PR the event can be captured with slash.power EXISTS or just slash EXISTS to catch by event type.
## Examples:
`slash EXISTS`

## 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: #1859closes: #2905

hard to debug crashes (among other things).

Description:
add boltdb implement for db interface.
The boltdb is safe and high performence embedded KV database. It is based on B+tree and Mmap.
Now it is maintained by etcd-io org. https://github.com/etcd-io/bbolt
It is much better than LSM tree (levelDB) when RANDOM and SCAN read.
Replaced #3604

* add boltdb for storage
* update boltdb in gopkg.toml
* update bbolt in Gopkg.lock
* dep update Gopkg.lock
* add boltdb'bucket when create Boltdb
* some modifies

* Remove deprecated PanicXXX functions from codebase
As per discussion over
[here](https://github.com/tendermint/tendermint/pull/3456#discussion_r278423492),
we need to remove these `PanicXXX` functions and eliminate our
dependence on them. In this PR, each and every `PanicXXX` function call
is replaced with a simple `panic` call.
* add a changelog entry
Fixes#3457
The topic of the issue is that : write a BlockRequest int requestsCh channel will create an timer at the same time that stop the peer 15s later if no block have been received . But pop a BlockRequest from requestsCh and send it out may delay more than 15s later. So that the peer will be stopped for error("send nothing to us").
Extracting requestsCh into its own goroutine can make sure that every BlockRequest been handled timely.
Instead of the requestsCh handling, we should probably pull the didProcessCh handling in a separate go routine since this is the one "starving" the other channel handlers. I believe the way it is right now, we still have issues with high delays in errorsCh handling that might cause sending requests to invalid/ disconnected peers.
* p2p: refactor Switch#Broadcast func
- call wg.Add only once
- do not call peers.List twice!
* bad for perfomance
* peers list can change in between calls!
Refs #3306
* p2p: use time.Ticker instead of RepeatTimer
no need in RepeatTimer since we don't Reset them
Refs #3306
* libs/common: remove RepeatTimer (also TimerMaker and Ticker interface)
"ancient code that’s caused no end of trouble" Ethan
I believe there's much simplier way to write a ticker than can be reset
