Log Message:
Fix https://sourceware.org/bugzilla/show_bug.cgi?id=34033

- Deprecate loc_ntoa because it does not specify the size of the destination
  buffer and replace it with loc_ntoa1
- Replace sprintf(3) with snprintf(3), checking for string overflow.

This removes all sprintf(3) uses in libc, except in compat/net/compat_ns_ntoa.c

Thanks to phone@ for reviewing and Florian Weimer for notifying us.
