[PATCH] Implement strlcpy [BZ #178]

[Florian Weimer]

This patch adds an implementation of strlcpy.

I think it shows that we can do much better than custom implementations 
in libbsd and random applications:

* This version is based on optimized strnlen and memcpy implementation.

* It has fortify support.

* In fortify mode, there a link-time warnings for common misuses.
   (The location of the warning could be improved,
   but this is a GCC issue.)

If this is patch is accepted, I will work on an implementation of 
strlcat along similar lines.
