14914827f0 Zero out a local variable also when PURIFY is not defined. 
This silence a warning brought up by valgrind whenever if_nametoindex
is used. This was already discussed in PR 166483, but the code
committed in r234329 guards the initilization with #ifdef PURIFY.
Therefore, valgrind still complains. Since this code is not performance
critical, always zero out the local variable to silence valgrind.

7253197882 libc: Use SOCK_CLOEXEC for various internal file descriptors. 
This change avoids undesirably passing some internal file descriptors to a
process created (fork+exec) by another thread.

Kernel support for SOCK_CLOEXEC was added in r248534, March 19, 2013.

cf0d539f8b Use the LLINDEX macro to access the link-level I/F index. This makes 
it possible to work with a different type for the sdl_index field --
it only requires a recompile.

d05090827f Back out the `hiding' of strlcpy and strlcat. Several people 
vocally objected to this safety belt.

5723e501ab `Hide' strlcpy and strlcat (using the namespace.h / __weak_reference 
technique) so that we don't wind up calling into an application's
version if the application defines them.

Inspired by:	qpopper's interfering and buggy version of strlcpy

e0554a531f Eliminate 61 warnings emitted at WARNS=2 (leaving 53 to go). 
Only warnings that could be fixed without changing the generated object
code and without restructuring the source code have been handled.
