The getline function returns the number of characters read, not
written. Use clearer text for this.

Update the documentation to reflect changes to the implementation in
r197752, which is related to handling of null buffer pointers. Also
make a few minor wording changes.

Reported by: jh@

Return -1 instead of 0 upon reaching EOF. This is somewhat ill-advised
because it means getdelim() returns -1 for both error and EOF, and
never returns 0. However, this is what the original GNU implementation
does, and POSIX inherited the bug.

Reported by: marcus@

- 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.
