Where possible, replace uses of the custom JSON library with the standard
library. The custom library treats interface and unnamed lteral types
differently, so this change avoids those even where it would probably be safe
to switch them.

The code in the Tendermint repository makes heavy use of import aliasing.
This is made necessary by our extensive reuse of common base package names, and
by repetition of similar names across different subdirectories.

Unfortunately we have not been very consistent about which packages we alias in
various circumstances, and the aliases we use vary. In the spirit of the advice
in the style guide and https://github.com/golang/go/wiki/CodeReviewComments#imports,
his change makes an effort to clean up and normalize import aliasing.

This change makes no API or behavioral changes. It is a pure cleanup intended
o help make the code more readable to developers (including myself) trying to
understand what is being imported where.

Only unexported names have been modified, and the changes were generated and
applied mechanically with gofmt -r and comby, respecting the lexical and
syntactic rules of Go.  Even so, I did not fix every inconsistency. Where the
changes would be too disruptive, I left it alone.

The principles I followed in this cleanup are:

- Remove aliases that restate the package name.
- Remove aliases where the base package name is unambiguous.
- Move overly-terse abbreviations from the import to the usage site.
- Fix lexical issues (remove underscores, remove capitalization).
- Fix import groupings to more closely match the style guide.
- Group blank (side-effecting) imports and ensure they are commented.
- Add aliases to multiple imports with the same base package name.

This is a mostly-automated fixup using Comby (https://comby.dev) to remove 
lexically-obvious redundant error checks. No functional changes are intended.

To reproduce the core change:

    # Collapse redundant error check conditionals
    % comby -in-place 'if err != nil {
       return err
    }
    return nil' 'return err' .go

    # Fold out unnecessary error temporaries
    % comby -in-place ':[spc~^\s*]err :[~:?]= :[any]
       return err' ':[spc]return :[any]' .go

Fixes #6479 and related cases.

Closes #5142

At Oasis we have spend some time writing a new Ed25519/X25519/sr25519 implementation called curve25519-voi.  This PR switches the import from ed25519consensus/go-schnorrkel, which should lead to performance gains on most systems.

Summary of changes:
 * curve25519-voi is now used for Ed25519 operations, following the existing ZIP-215 semantics.
 * curve25519-voi's public key cache is enabled (hardcoded size of 4096 entries, should be tuned, see the code comment) to accelerate repeated Ed25519 verification with the same public key(s).
 * (BREAKING) curve25519-voi is now used for sr25519 operations.  This is a breaking change as the current sr25519 support does something decidedly non-standard when going from a MiniSecretKey to a SecretKey and or PublicKey (The expansion routine is called twice).  While I believe the new behavior (that expands once and only once) to be more "correct", this changes the semantics as implemented.
 * curve25519-voi is now used for merlin since the included STROBE implementation produces much less garbage on the heap.

Side issues fixed:
 * The version of go-schnorrkel that is currently imported by tendermint has a badly broken batch verification implementation.  Upstream has fixed the issue after I reported it, so the version should be bumped in the interim.

Open design questions/issues:
 * As noted, the public key cache size should be tuned.  It is currently backed by a trivial thread-safe LRU cache, which is not scan-resistant, but replacing it with something better is a matter of implementing an interface.
 * As far as I can tell, the only reason why serial verification on batch failure is necessary is to provide more detailed error messages (that are only used in some unit tests).  If you trust the batch verification to be consistent with serial verification then the fallback can be eliminated entirely (the BatchVerifier provided by the new library supports an option that omits the fallback if this is chosen as the way forward).
 * curve25519-voi's sr25519 support could use more optimization and more eyes on the code.  The algorithm unfortunately is woefully under-specified, and the implementation was done primarily because I got really sad when I actually looked at go-schnorrkel, and we do not use the algorithm at this time.

Addresses a beginning component of #6255

## Description

Internalize some libs. This reduces the amount ot public API tendermint is supporting. The moved libraries are mainly ones that are used within Tendermint-core.

## Description

- Add `context.Context` to Privval interface

This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.

## Description

- return errors on `loadFilePv`

closes #6182

## Description

- removes blocktimeiota 
- 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

Co-authored-by: Anton Kaliaev <anton.kalyaev@gmail.com>

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).

Refs #5550

Partially closes #5550

Co-authored-by: Anton Kaliaev <anton.kalyaev@gmail.com>

## 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


gonna do a third PR that tackles the non test cases

* test-vectors for backwards compatibility:

 - copy & paste test-vectors from v0.33.5 to ensure
 backwards compatibility for vote's SignBytes

* WIP: everything besides time seems to match :-/

* almost

* Found the culprit: field nums weren't consecutive ints ...

* fix order of partset header too

* this last votes-related test can easily be fixed

* some minor changes and fix last failing test

* move proto types back to stdtime, fix various linting

* use libs/protoio

* remvoe commented code

* add comments

* fix tests

* uncomment testscases

* dont ignore error panic

* fix signable test

* fix happy path testing

* fix comment
