When using the RPC client in my test suite (with -race enabled), I do a lot of Subscribe/Unsubscribe operations, at some point (randomly) the race detector returns the following warning:
WARNING: DATA RACE
Read at 0x00c0009dbe30 by goroutine 31:
runtime.mapiterinit()
/usr/local/go/src/runtime/map.go:804 +0x0

Turns out that the redoSubscriptionAfter is not protecting the access to subscriptions.
The following change protects the read access to the subscription map behind the mutex

This PR is related to #3107 and a continuation of #3351
It is important to emphasise that in the privval original design, client/server and listening/dialing roles are inverted and do not follow a conventional interaction.
Given two hosts A and B:
Host A is listener/client
Host B is dialer/server (contains the secret key)
When A requires a signature, it needs to wait for B to dial in before it can issue a request.
A only accepts a single connection and any failure leads to dropping the connection and waiting for B to reconnect.
The original rationale behind this design was based on security.
Host B only allows outbound connections to a list of whitelisted hosts.
It is not possible to reach B unless B dials in. There are no listening/open ports in B.
This PR results in the following changes:
Refactors ping/heartbeat to avoid previously existing race conditions.
Separates transport (dialer/listener) from signing (client/server) concerns to simplify workflow.
Unifies and abstracts away the differences between unix and tcp sockets.
A single signer endpoint implementation unifies connection handling code (read/write/close/connection obj)
The signer request handler (server side) is customizable to increase testability.
Updates and extends unit tests
A high level overview of the classes is as follows:
Transport (endpoints): The following classes take care of establishing a connection
SignerDialerEndpoint
SignerListeningEndpoint
SignerEndpoint groups common functionality (read/write/timeouts/etc.)
Signing (client/server): The following classes take care of exchanging request/responses
SignerClient
SignerServer

I'm setting up all peers dynamically by calling dial_peers, so p2p.seeds in configs is empty, and I'm seeing error log a lot in logs.
* p2p: fix false-positive error logging when stopping connections
This changeset fixes two types of false-positive errors occurring during
connection shutdown.
The first occurs when the process invokes FlushStop() or Stop() on a
connection. While the previous behavior did properly wait for the sendRoutine
to finish, it did not notify the recvRoutine that the connection was shutting
down. This would cause the recvRouting to receive and error when reading and
log this error. The changeset fixes this by notifying the recvRoutine that
the connection is shutting down.
The second occurs when the connection is terminated (gracefully) by the other side.
The recvRoutine would get an EOF error during the read, log it, and stop the connection
with an error. The changeset detects EOF and gracefully shuts down the connection.
* bring back the comment about flushing
* add changelog entry
* listen for quitRecvRoutine too
* we have to call stopForError
Otherwise peer won't be removed from the peer set and maybe readded
later.

* Fix bug in sendRequest()
If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.
While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.
