Next round of stdio changes: Remove all inlining of stdio operations and

move the definition of the type backing FILE (struct __sFILE) into an
internal header.
- Remove macros to inline certain operations from stdio.h.  Applications
  will now always call the functions instead.
- Move the various foo_unlocked() functions from unlocked.c into foo.c.
  This lets some of the inlining macros (e.g. __sfeof()) move into
  foo.c.
- Update a few comments.
- struct __sFILE can now go back to using mbstate_t, pthread_t, and
  pthread_mutex_t instead of knowing about their private, backing types.
