The abi package already supports function overload by adding a suffix to the overloaded function name, but it uses the function name with suffix to calculate signature(both for the event and method).

This PR fixes it by adding a new field named RawName, which can be used to calcuate all signatures but use Name to distinguish different overloaded function.

Fixed assigning values to variables we don't end up using.

This PR will will break existing UIs, since it changes all calls like ApproveSignTransaction to be on the form ui_approveSignTransaction.

This is to make it possible for the UI to reuse the json-rpc library from go-ethereum, which uses this convention.

Also, this PR removes some unused structs, after import/export were removed from the external api (so no longer needs internal methods for approval)

One more breaking change is introduced, removing passwords from the ApproveSignTxResponse and the likes. This makes the manual interface more like the rulebased interface, and integrates nicely with the credential storage. Thus, the way it worked before, it would be tempting for the UI to implement 'remember password' functionality. The way it is now, it will be easy instead to tell clef to store passwords and use them.

If a pw is not found in the credential store, the user is prompted to provide the password.

UnmarshalPubkey across the codebase.
