Jakub Zych 39677f1819 fix(diary): retire replaced daily writers and serialise ApplyGlobals ...

- install and Reset retire the channels they replace: a retired daily
  writer appends a late record and closes the file again, so no record is
  lost and no descriptor stays open; diary.Close keeps reopening the
  installed writers on the next record
- ApplyGlobals holds the setup lock for its whole run (lock-free
  installLocked and setVerbosityLocked), so concurrent calls rebuild the
  channels once (WR-06)
