  Log Message:
  -----------
  Implement thread-safety in the logging system

This chooses a method that minimizes the need to alter the way log messages are written.
Only a few places that did unusual things with the logger needed to be updated.

  Log Message:
  -----------
  Another go at refactoring distributor.cpp (builds and runs successfully)

This is part-way though a refactor, but I'm not committing myself to completing
it; publishing for the comments and discussion.

This solves PR #5198's compile errors about undefined references, but the
solution here is to expand the templates into the multiple hardcoded copies
block starting with `switch(events_.sdl_button_down_event)`.
