77b79fa6ef60d363ca720cef5473f1a2c45099a3 refactor: Error message bilingual_str consistency (Wladimir J. van der Laan)

Pull request description:

  A straightforward and hopefully uncontroversial refactor to improve consistency.

  - Move the decision whether to translate an individual error message to where it is defined. This simplifies call sites: no more `InitError(Untranslated(SomeFunction(...)))`.

  - Make all functions in `util/error.h` consistently return a   `bilingual_str`. We've decided to use this as error message type so let's roll with it.

  This has no functional changes: no messages are changed, no new translation messages are defined.

  Also make a function static that can be static.
