- Add getdelim(), getline(), stpncpy(), strnlen(), wcsnlen(),

  wcscasecmp(), and wcsncasecmp().
- Make some previously non-standard extensions visible
  if POSIX_VISIBLE >= 200809.
- Use restrict qualifiers in stpcpy().
- Declare off_t and size_t in stdio.h.
- Bump __FreeBSD_version in case the new symbols (particularly
  getline()) cause issues with ports.
