  reflog: integrate into the ref writing
  
  Whenever a reference is created or updated, we need to write to the
  reflog regardless of whether the user gave us a message, so we shouldn't
  leave that to the ref frontend, but integrate it into the backend.
  
  This also eliminates the race between ref update and writing to the
  reflog, as we protect the reflog with the ref lock.
  
  As an additional benefit, this reflog append on the backend happens by
  appending to the file instead of parsing and rewriting it.
