`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
* lint: golint issue fixes
- on my local machine golint is a lot stricter than the bot so slowly going through and fixing things.

As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states).
In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client.
And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure:
enum CheckTxType {
New = 0;
Recheck = 1;
}
message RequestCheckTx {
bytes tx = 1;
CheckTxType type = 2;
}
* Refactor ABCI CheckTx to notify of recheck
As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for:
1. a flag indicating whether a query is a recheck or not (and allows for
possible future, more nuanced states)
2. an `additional_data` bytes array to provide information for those more
nuanced states.
In order to pass this extended information through to the ABCI app, the
`proxy.AppConnMempool` (and, for consistency, the
`proxy.AppConnConsensus`) interface seems to need to be refactored.
Commits:
* Fix linting issue
* Add CHANGELOG_PENDING entry
* Remove extraneous explicit initialization
* Update ABCI spec doc to include new CheckTx params
* Rename method param for consistency
* Rename CheckTxType enum values and remove additional_data param
