signer, clef: implement EIP191/712 (#17789)
* Named functions and defined a basic EIP191 content type list
* Written basic content type functions
* Added ecRecover method in the clef api
* Updated the extapi changelog and addded indications in the README
* Changed the version of the external API
* Added tests for 0x45
* Implementing UnmarshalJSON() for TypedData
* Working on TypedData
* Solved the auditlog issue
* Changed method to signTypedData
* Changed mimes and implemented the 'encodeType' function for EIP-712
* Polished docstrings, ran goimports and swapped fmt.Errorf with errors.New where possible
* Drafted recursive encodeData
* Ran goimports and gofmt
* Drafted first version of EIP-712, including tests
* Temporarily switched to using common.Address in tests
* Drafted text/validator and and rewritten []byte as hexutil.Bytes
* Solved stringified address encoding issue
* Changed the property type required by signData from bytes to interface{}
* Fixed bugs in 'data/typed' signs
* Brought legal warning back after temporarily disabling it for development
* Added example RPC calls for account_signData and account_signTypedData

### Changelog for external API
|
||||
|
||||
#### 5.0.0
|
||||
|
||||
* The external `account_EcRecover`-method was reimplemented.
|
||||
* The external method `account_sign(address, data)` was replaced with `account_signData(contentType, address, data)`.
|
||||
The addition of `contentType` makes it possible to use the method for different types of objects, such as:
|
||||
* signing data with an intended validator (not yet implemented)
|
||||
* signing clique headers,
|
||||
* signing plain personal messages,
|
||||
* The external method `account_signTypedData` implements [EIP-712](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md) and makes it possible to sign typed data.
|
||||
|
||||
#### 4.0.0
|
||||
|
||||
* The external `account_Ecrecover`-method was removed.

|

### Changelog for internal API (ui-api)
|
||||
|
||||
### 3.1.0
|
||||
|
||||
* Add `ContentType string` to `SignDataRequest` to accommodate the latest EIP-191 and EIP-712 implementations.
|
||||
|
||||
### 3.0.0
|
||||
|
||||
* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
