## Description
R4R
Closes: #9912
This PR introduces 1 new middleware:
- `TipsMiddleware`: transfer tip from tipper to feePayer when relevant.
It also makes sure in the DIRECT_AUX sign mode handler that the fee payer cannot use that sign mode.
Depends on:
- [x] #10028
- [x] #10268
- [x] #10322

## Description
Closes: #10443
For creating an intermediary/auxiliary tx (e.g. by the tipper in tipped transactions), using the existing `client.TxBuilder` is awkward. We propose a new client-side builder for this purpose.
API Usage (e.g. how the tipper would programmtically use this):
```go
// Note: there's no need to use clientCtx.TxConfig anymore!
bldr := clienttx.NewAuxTxBuilder()
err := bldr.SetMsgs(msgs...)
bldr.SetAddress("cosmos1...")
bldr.SetMemo(...)
bldr.SetTip(...)
bldr.SetPubKey(...)
err := bldr.SetSignMode(...) // DIRECT_AUX or AMINO, or else error
// ... other setters are available
// Get the bytes to sign.
signBz, err := bldr.GetSignBytes()
// Sign the bz using your favorite method.
sig, err := privKey.sign(signBz)
// Set the signature
bldr.SetSig(sig)
// Get the final auxSignerData to be sent to the fee payer
auxSignerData, err:= bldr.GetAuxSignerData()
```
auxSignerData is a protobuf message, whose JSON reprensentation looks like:
```json
{
"address": "cosmos1...",
"mode": "SIGN_MODE_{DIRECT_AUX,LEGACY_AMINO_JSON}",
"sign_doc": {
"body_bytes": "{base64 bytes}",
"public_key": {
"@type": "cosmos.sepc256k1.PubKey",
"key": "{base64 bytes}"
},
"chain_id": "...",
"account_number": 24,
"sequence": 42,
"tip": {
"amount": [{ "denom": "uregen", "amount": 1000 }],
"tipper": "cosmos1..."
}
},
"sig": "{base64 bytes}"
}
```
Then the fee payer would use the TxBuilder to construct the final TX, with a new helper method: `AddAuxSignerData`:
```go
// get auxSignerData from AuxTxBuilder
auxSignerData := ...
txBuilder := txConfig.NewTxBuilder()
err := txBuilder.AddAuxSignerData(auxSignerData)
// Set fee payer data
txBuilder.SetFee()
txBuilder.SetGasLimit()
txBuilder.SetFeePayer()
sigs, err := txBuilder.GetSignaturesV2()
auxSig := sigs[0] // the aux signer's signature
// Set all signer infos (1st round of calling SetSignatures)
txBuilder.SetSignatures(
auxSig, // The aux SignatureV2
signing.SignatureV2{...}, // The feePayer's SignatureV2
)
// Sign
signBz, err = encCfg.TxConfig.SignModeHandler().GetSignBytes(...)
feepayerSig, err := feepayerPriv.Sign(signBz)
// Set all signatures (2nd round of calling SetSignatures)
txBuilder.SetSignatures(
auxSig, // The aux SignatureV2
signing.SignatureV2{feepayerSig, ...}, // The feePayer's SignatureV2
)
```

## Description
Revert #10268
As part of the TX working group, we decided not to introduce a new sign mode for tipper signing. The tipper will use amino-json to sign via ledger (see #10346).
Also, add `signing.SignerData#Address` (will be used in subsequent PR #10346)

## Description
It is possible to submit a TX with a fees object containing a Coin with a nil amount. This results in a rather cryptic redacted panic response when the basic validation checks fee Coins for negative amounts.
This PR adds an additional check for nil to provide a friendlier error message.

## Description
ref: #9585
This PR if the 1st step (out of 2) in the #9585 refactor. It transforms baseapp's ABCI {Check,Deliver}Tx into middleware stacks. A middleware is defined by the following interfaces:
```go
// types/tx package
type Handler interface {
CheckTx(ctx context.Context, tx sdk.Tx, req abci.RequestCheckTx) (abci.ResponseCheckTx, error)
DeliverTx(ctx context.Context, tx sdk.Tx, req abci.RequestDeliverTx) (abci.ResponseDeliverTx, error)
SimulateTx(ctx context.Context, tx sdk.Tx, req RequestSimulateTx) (ResponseSimulateTx, error)
}
type Middleware func(Handler) Handler
```
This Pr doesn't migrate antehandlers, but only baseapp's runTx and runMsgs as middlewares. It bundles antehandlers into one single middleware (for now).
More specifically, it introduces the 5 following middlewares:
| Middleware | Description |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| RunMsgsTxMiddleware | This middleware replaces the old baseapp's `runMsgs`. |
| LegacyAnteMiddleware | This middleware is temporary, it bundles all antehandlers into one middleware. It's only created for the purpose of breaking the refactor into 2 pieces. **It will be removed in Part 2**, and each antehandler will be replaced by its own middleware. |
| IndexEventsTxMiddleware | This is a simple middleware that chooses which events to index in Tendermint. Replaces `baseapp.indexEvents` (which unfortunately still exists in baseapp too, because it's used to index Begin/EndBlock events) |
| RecoveryTxMiddleware | This index recovers from panics. It replaces baseapp.runTx's panic recovery. |
| GasTxMiddleware | This replaces the [`Setup`](https://github.com/cosmos/cosmos-sdk/blob/master/x/auth/ante/setup.go) Antehandler. It sets a GasMeter on sdk.Context. Note that before, GasMeter was set on sdk.Context inside the antehandlers, and there was some mess around the fact that antehandlers had their own panic recovery system so that the GasMeter could be read by baseapp's recovery system. Now, this mess is all removed: one middleware sets GasMeter, another one handles recovery. |
