client: raise ResponseError in _readchannel() Make it clearer that this is an unrecoverable communication error. ServerError alone is not always unrecoverable, as CapabilityError is considered a subtype of it. This way, a caller can check for ResponseError to identify errors that require reopening the client to recover.
