This change aims to keep versions of mockery consistent across developer laptops.

This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.

Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397

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.

Follow up from PR: #6740

This changes adds an `MempoolError` field to the `ResponseCheckTx`. This will allow clients to understand that their transaction was rejected from the mempool despite passing the ABCI check. 

This change also updates the code to make use of early returns to prevent highly nested code blocks. Namely, it returns when the type assertion fails at the beginning of the method, instead of wrapping the entire method in a large if statement. This has a somewhat large effect on the diff as rendered by github.

addresses: #3546

There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.

## 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 sr25519 as a validator key option. We support the crypto in tendermint and added batch verification recently.

Fixes the race condition between a callback being set and called during ReCheckTx. Note, I do not see equivalent logic in the gRPC client (anymore) as #5439 suggests, so only the socket client was updated.

closes: #5439

## Description

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


Closes: #5939

## Description

- bump gogoproto (1.3.2)
- regenerate proto files

Closes: #XXX

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

Fixes #5840.

# Description

Proto definitions file was moved and link was broken. Fixed as relative link.

Migrate ABCI to use protoio (uint64 length delimitation) instead of specific int64 length delimiters.

Closes: #5783

`abci.Client`:

- Sync and Async methods now accept a context for cancellation
    * grpc client uses context to cancel both Sync and Async requests
    * local client ignores context parameter
    * socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that

- Async methods return an error
    * socket client returns an error immediately if queue is full for Async requests
    * local client always returns nil error
    * grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)

- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)

`mempool.TxInfo`

- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request

Closes #5190

## Description

- add `AbciVersion` RequestInfo

Closes: #2804

Fixes #5540, fixes #2965. This is a hack that patches over the problem, but really the whole async handling in gRPC should be redesigned, as should ReqRes callback dispatch.

Fixes #5439. This is really a workaround for #5519 (unless we require async implementations to return ordered responses, but that kind of defeats the purpose of having an async API).

Secp256k1 was removed in the protobuf migration, this pr adds it back in order to provide this functionality for users (band)

Closes: #5495

Remove Response/Request SetOption from ABCI.

This caused the node to crash whenever any state sync-related request was called via the ABCI UNIX socket client.

## Description

Enable errcheck linter throughout the codebase

Closes: #5059

## Description

Work towards enabling errcheck

ref #5059

* libs/bits: inline defer and change order of mutexes

Closes #3217

* abci/client: unexpose StopForError func

a) it's not called outside
b) the reason for exposing it in the first place is unclear
c) Stop already exist if someone from outside wants to stop the client

Adds a genesis parameter `initial_height` which specifies the initial block height, as well as ABCI `RequestInitChain.InitialHeight` to pass it to the ABCI application, and `State.InitialHeight` to keep track of the initial height throughout the code. Fixes #2543, based on [RFC-002](https://github.com/tendermint/spec/pull/119). Spec changes in https://github.com/tendermint/spec/pull/135.

Fixes #5177.

adds blockstore interface to evidence and adds fix to byzantine test

## Description

THis pr adds `json_name` to replace proto generated json tags. 

Closes: #5111

## 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

Closes #5125

## Description

add more error checks to tests


gonna do a third PR that tackles the non test cases

- the sequence does not start with 1
- RequestDeliverTx has out-of-order field number

Closes #5115

Reorganizes the Protobuf schemas. It is mostly bikeshedding, so if something is contentious or causes a lot of extra work then I'm fine with reverting. Some Protobuf and Go import paths will change.

* Move `abci/types/types.proto` to `abci/types.proto`.

* Move `crypto/keys/types.proto` and `crypto/merkle/types.proto` to `crypto/keys.proto` and `crypto/proof.proto`.

* Drop the use of `msgs` in filenames, as "message" is a very overloaded term (all Protobuf types are messages, and we also have `message Message`). Use `types.proto` as a catch-all, and otherwise name files by conceptual grouping instead of message kind.

Fixes some minor issues with Protobuf enums, not likely to break anything.

Branched off of #5096, rebase to `master` before merging.
