Ulrich Drepper e35f65ea8d unsigned long it better for the size arguments

are not a direct measure of memory size.

Ulrich Drepper 3a2c02424d Cache network interface information
Whenever getaddrinfo needed network interface information it used the
netlink interface to read the information every single time.  The
problem is that this information can change at any time.

The patch implements monitoring of the network interfaces through
nscd.  If no change is detected the previously read information can
be reused (which is the norm).  This timestamp information is also
made available to other processes using the shared memory segment
between nscd and those processes.
