c044cf14b0 Fix wrong copying processing for last bytes in x86-32 wcscpy 
Wrong copy algorithm for last bytes, not thread safety.
In some particular cases it uses the destination
memory beyond the string end for
16-byte load, puts changes into that part that is relevant
to destination string and writes whole 16-byte chunk into memory.
I have a test case where the memory beyond the string end contains
malloc/free data, that appear corrupted in case free() updates
it in between the 16-byte read and 16-byte write.

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.
