Robustify libc-side nscd database reader.
The nscd database mapped in processes can change at any time. We have to be more vigilant when it comes to using that memory. Test the data entries are valid in their entire size, don't read data again from memory once we verified it, and make sure the trailing pointer is not going off the deep end.
