Closes #5145

evidence: modify evidence types (#5342)

light: detect light client attacks (#5344)

evidence: refactor evidence pool (#5345)

abci: application evidence prepared by evidence pool (#5354)

Revert the JSON-RPC/WebSocket response serialization format to the
standard way (i.e. a single RPC response per WebSocket text message) to
avoid breaking clients.

Serialization format changes will be discussed in an upcoming ADR.

Closes: #5373

Fixes a couple of test data races. `testing.T` is not concurrency-safe and should not be used in goroutines at all.

Broke in #5356.

ref #5059

* docs: goleveldb is much more stable now

Refs https://github.com/syndtr/goleveldb/issues/226#issuecomment-682495490

* rpc/core/events: make sure WS client receives every event

previously, if the write buffer was full, the response would've been
lost without any trace (log msg, etc.)

* rpc/jsonrpc/server: set defaultWSWriteChanCapacity to 1

Refs #3905
Closes #3829

setting write buffer capacity to 1 makes transactions count per block
more stable and also reduces the pauses length by 20s.

before: https://github.com/tendermint/tendermint/issues/3905#issuecomment-681854328 net.Read - 20s
after: net.Read - 0.66s

also, remove `/unsafe_start_cpu_profiler`, `/unsafe_stop_cpu_profiler`
and `/unsafe_write_heap_profile` in favor of pprof server functionality.

## Description

This PR aims to make the crypto.PubKey interface more intuitive. 

Changes: 

- `VerfiyBytes` -> `VerifySignature`

Before `Bytes()` was amino encoded, now since it is the byte representation should we get rid of it entirely?

EDIT: decided to keep `Bytes()` as it is useful if you are using the interface instead of the concrete key

Closes: #XXX

Adds a genesis parameter `initial_height` which specifies the initial block height, as well as ABCI `RequestInitChain.InitialHeight` to pass it to the ABCI application, and `State.InitialHeight` to keep track of the initial height throughout the code. Fixes #2543, based on [RFC-002](https://github.com/tendermint/spec/pull/119). Spec changes in https://github.com/tendermint/spec/pull/135.

adds blockstore interface to evidence and adds fix to byzantine test

Also, wrote a test for WriteRPCResponseHTTPError and used it with correct status codes according to https://www.jsonrpc.org/historical/json-rpc-over-http.html#response-codes

## Description

THis pr adds `json_name` to replace proto generated json tags. 

Closes: #5111

## Description

This PR wraps the stdlib sync.(RW)Mutex & godeadlock.(RW)Mutex. This enables using go-deadlock via a build flag instead of using sed to replace sync with godeadlock in all files

Closes: #3242

## Description

this log message was marked as not useful and in the issue it was proposed to move it to debug. I am going with this path for now. After we have refactored the logger we shold go through the codebase in order to clean our log statements. 

Closes: #2101

## Description

add more error checks to tests


gonna do a third PR that tackles the non test cases

Reorganizes the Protobuf schemas. It is mostly bikeshedding, so if something is contentious or causes a lot of extra work then I'm fine with reverting. Some Protobuf and Go import paths will change.

* Move `abci/types/types.proto` to `abci/types.proto`.

* Move `crypto/keys/types.proto` and `crypto/merkle/types.proto` to `crypto/keys.proto` and `crypto/proof.proto`.

* Drop the use of `msgs` in filenames, as "message" is a very overloaded term (all Protobuf types are messages, and we also have `message Message`). Use `types.proto` as a catch-all, and otherwise name files by conceptual grouping instead of message kind.

## Description

partially cleanup in preparation for errcheck

i ignored a bunch of defer errors in tests but with the update to go 1.14 we can use `t.Cleanup(func() { if err := <>; err != nil {..}}` to cover those errors, I will do this in pr number two of enabling errcheck.

Closes #4549

## Description

This PR moves all proto files under one dir (`/proto`). The script to generate adding functionality to copy the files that still need to be in the same place. (abci & rpc)

renames every proto package from `tendermint.proto.<pkg_name>` to `tendermint.<pkg_name>`

Removes unneeded types in privval proto directory

Closes: #XXX

Closes #4763

* check for Error after for loop ends

so we don't silently ignore errors, which would lead to clients getting
incomplete results

Refs https://github.com/tendermint/tendermint/pull/4979/files#r436511572

Migrates the `rpc` package to use new JSON encoder in #4955. Branched off of that PR.

Tests pass, but I haven't done any manual testing beyond that. This should be handled as part of broader 0.34 testing.
