This issue is related to #3107
This is a first renaming/refactoring step before reworking and removing heartbeats.
As discussed with @Liamsi , we preferred to go for a couple of independent and separate PRs to simplify review work.
The changes:
Help to clarify the relation between the validator and remote signer endpoints
Differentiate between timeouts and deadlines
Prepare to encapsulate networking related code behind RemoteSigner in the next PR
My intention is to separate and encapsulate the "network related" code from the actual signer.
SignerRemote ---(uses/contains)--> SignerValidatorEndpoint <--(connects to)--> SignerServiceEndpoint ---> SignerService (future.. not here yet but would like to decouple too)
All reconnection/heartbeat/whatever code goes in the endpoints. Signer[Remote/Service] do not need to know about that.
I agree Endpoint may not be the perfect name. I tried to find something "Go-ish" enough. It is a common name in go-kit, kubernetes, etc.
Right now:
SignerValidatorEndpoint:
handles the listener
contains SignerRemote
Implements the PrivValidator interface
connects and sets a connection object in a contained SignerRemote
delegates PrivValidator some calls to SignerRemote which in turn uses the conn object that was set externally
SignerRemote:
Implements the PrivValidator interface
read/writes from a connection object directly
handles heartbeats
SignerServiceEndpoint:
Does most things in a single place
delegates to a PrivValidator IIRC.

* node: decrease retry conn timeout in test
Should fix#3256
The retry timeout was set to the default, which is the same as the
accept timeout, so it's no wonder this would fail. Here we decrease the
retry timeout so we can try many times before the accept timeout.
* p2p: increase handshake timeout in test
This fails sometimes, presumably because the handshake timeout is so low
(only 50ms). So increase it to 1s. Should fix#3187
* privval: fix race with ping. closes#3237
Pings happen in a go-routine and can happen concurrently with other
messages. Since we use a request/response protocol, we expect to send a
request and get back the corresponding response. But with pings
happening concurrently, this assumption could be violated. We were using
a mutex, but only a RWMutex, where the RLock was being held for sending
messages - this was to allow the underlying connection to be replaced if
it fails. Turns out we actually need to use a full lock (not just a read
lock) to prevent multiple requests from happening concurrently.
* node: fix test name. DelayedStop -> DelayedStart
* autofile: Wait() method
In the TestWALTruncate in consensus/wal_test.go we remove the WAL
directory at the end of the test. However the wal.Stop() does not
properly wait for the autofile group to finish shutting down. Hence it
was possible that the group's go-routine is still running when the
cleanup happens, which causes a panic since the directory disappeared.
Here we add a Wait() method to properly wait until the go-routine exits
so we can safely clean up. This fixes#2852.

Ref: #2563
I added IPC as an unencrypted alternative to SocketPV.
Besides I fixed the following aspects of SocketPV:
Added locking since we are operating on a single socket
The connection deadline is extended every time a successful packet exchange happens; otherwise the connection would always die permanently x seconds after the connection was established.
Added a ping/heartbeat mechanism to keep the connection alive; native TCP keepalives do not work in this use-case
* Extend the SecureConn socket to extend its deadline
* Add locking & ping/heartbeat packets to SocketPV
* Implement IPC PV and abstract socket signing
* Refactored IPC and SocketPV
* Implement @melekes comments
* Fixes to rebase
* p2p: NodeInfo is an interface
* (squash) fixes from review
* (squash) more fixes from review
* p2p: remove peerConn.HandshakeTimeout

* fixes from review
* remove test code from peer.RemoteIP()

* p2p: fix testNodeInfo naming
* p2p: remove unused var
* remove testRandNodeInfo
* fix linter
* fix retry dialing self

* stop node upon receiving SIGTERM or CTRL-Ceven during genesis sleep by setting up interrupt before starting a node

```
E[09-24|10:13:15.805] Not stopping PubSub -- have not been started yet module=pubsub impl=PubSub
```
being printed on exit
This also refactors the prior mempool to filter to be known as
"precheck filter" and this new filter is called "postcheck filter"
This PR also fixes a bug where the precheck filter previously didn't
account for the amino overhead, which could a maliciously sized tx to
halt blocks from getting any txs in them.

* avoid cyclic imports
* you can do better Go, come on
* remove testdouble package
Handshaker was removed from proxy package so it can be called
independently of starting the abci app connections and can return a
result to the caller.
We are swapping the exisiting listener implementation with the newly
introduced Transport and its default implementation MultiplexTransport,
removing a large chunk of old connection setup and handling scattered
over the Peer and Switch code. The Switch requires a Transport now and
handles externally passed Peer filters.
* remove ConsensusParams.TxSize and ConsensusParams.BlockGossip
Refs #2347
* block part size is now fixed
Refs #2347
* use max data size, not max bytes for tx limit
Refs #2347
