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.

rtld, i386: Fix cfi directive in audit trampoline code
...
_dl_runtime_profile function has wrong cfi directive when
rewinding stack back for the pltexit path.
Only 8 bytes - 2 'pop edx' instructions from the pltentry-only
code should be rewinded back.
With attached patch, I'm able to rewind stack correctly
throught the rtld code from audit library callback.
