- Use an initializer macro to initialize fields in 'fake' FILE objects used

  by *sprintf(), etc.
- Explicitly initialize _fl_mutex to PTHREAD_MUTEX_INITIALIZER for all FILE
  objects.  This is currently a nop on FreeBSD, but is import for other
  platforms (or in the future) where PTHREAD_MUTEX_INITIALIZER is not simply
  zero.
