- merges block params in abci and core state
- spec change: https://github.com/tendermint/spec/pull/248


Closes: #5939

## Description

- Query validator key when a remote signer is used. This is supported gRPC remote signing and filePV only. 


Closes: #3009

Fixes #5866. Inbound traffic monitoring (and by extension inbound rate limiting) was inadvertently removed in 660e72a.

## Description

Hardcode ed25519 to dialTCPFn in e2e tests. 

I will backport `DefaultRequestHandler` fixes

This will be replaced when grpc is implemented.

This is so that the `privval` package will not be affected when we refactor `p2p` (#5670). We will be migrating to gRPC shortly (#4698).

Partially closes #5550

## Description

make response values non nullable in privval

Does this need a changelog for master?

Closes: #5581 

cc @tarcieri

Partial fix for #5291. For details, see [README.md](https://github.com/tendermint/tendermint/blob/erik/e2e-tests/test/e2e/README.md) and [RFC-001](https://github.com/tendermint/tendermint/blob/master/docs/rfc/rfc-001-end-to-end-testing.md).

This only includes a single test case under `test/e2e/tests/`, as a proof of concept - additional test cases will be submitted separately. A randomized testnet generator will also be submitted separately, there a currently just a handful of static testnets under `test/e2e/networks/`. This will eventually replace the current P2P tests and run in CI.

Fixes #5371.

Required for #5291 to set timeouts for remote signers.

## Description

Work towards enabling errcheck

ref #5059

## Description

Add chainid to requests to privval. This is a non-breaking change and hardware devices can opt to ignore the field.
 
Closes: #4503 

Took the approach of passing chainID to the client instead of modifying `GetPubKey` because it would lead to a larger change throughout the codebase and in some places it could get tricky to get chainID.

## Description

Add test vectors for all reactors

- [x] state-sync
- [x] privval
- [x] mempool
- [x] p2p
- [x] evidence
- [ ] light?

this PR is primarily oriented at testvectors for things going over the wire. should we expand the testvectors into types as well?

Closes: #XXX

Closes #5112

## 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

add more error checks to tests

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
