Message:
Use G_GNUC_WARN_UNUSED_RESULT

Have gcc warn us when we ignore the result of a function that requires
the caller to free the result, or an initilization function that can
fail.  This might help (slightly) with preventing leaks and segfaults.

Additionally changed some functions that should never fail to not
return values.  (The owl_list_* functions changed only fail if
list->size < 0, which we assume is not the case elsewhere.)
