This change adds some polish to the upgrading instructions for 0.34. The only substantive changes include:
* Calling out ABCI-impacting changes explicitly in the "ABCI Changes" section, even if those changes are also mentioned elsewhere
* Removes `ProofOfTrialPeriod` from consensus params; this change was introduced and then removed.
found out this issue when trying to decouple mempool reactor with its
underlying clist implementation.
according to its comment, the test `TestReactorNoBroadcastToSender` is
intended to make sure that a peer shouldn't send tx back to its origin.
however, the current test forgot to init peer state key, thus the code
will get stuck at waiting for peer to catch up state *instead of* skipping
sending tx back:
b8d08b9ef4/mempool/reactor.go (L216-L226)
this PR fixes the issue by init peer state key.
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.

## Description
This PR adds support for badgerdb, rocksdb and boltdb within the build options.
RocksDB builds correctly.
```
make build TENDERMINT_BUILD_OPTIONS=rocksdb
CGO_ENABLED=1 go build -mod=readonly -ldflags "-X github.com/tendermint/tendermint/version.GitCommit=`git rev-parse --short=8 HEAD` -s -w " -trimpath -tags 'tendermint rocksdb' -o build/tendermint ./cmd/tendermint/
tendermint on master [$!] via 🐹 v1.15.2 took 19s
```
Closes: #5355
## Description
Add a sentence on `initial_height`.
There will be a section in the spec repo explaining the genesis more in depth as this is something that will affect both clients
Closes: #XXX
## Description
Check block protocol version in header validate basic.
I tried searching for where we check the P2P protocol version but was unable to find it. When we check compatibility with a node we check we both have the same block protocol and are on the same network, but we do not check if we are on the same P2P protocol. It makes sense if there is a handshake change because we would not be able to establish a secure connection, but a p2p protocol version bump may be because of a p2p message change, which would go unnoticed until that message is sent over the wire. Is this purposeful?
Closes: #4790
* 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 #3905Closes#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
* rpc/jsonrpc/server: buffer writes and avoid io.ReadAll during read
## Description
Part of the issue is to add metrics to the websocket connection. It seems this would require some moving around of things in the node pkg. I opted to not make this change now, and wait for when we do a node pkg refactor.
If someone disagrees with this appraoch please let me know, I can attempt to get metrics into the rpc layer.
There is not a need to update documentation as it already states this metric is a histogram..
Closes: #1791
## Description
Add missing metrics.
`Blockchain/v2` exposes metrics for events. I don't find these as something a node operator should utilize as it does not bring insight.
Closes: #XXX
On startup, the peer-to-peer stack may have peers connected before the state sync process begins, causing these to not trigger `AddPeer` events and thus not be used for snapshot discovery. Broadcasting a snapshot request to these explicitly makes sure we discover snapshots from existing peers as well.
