[PATCH] lib: string.c: Added a funktion function strzcpy

[Rickard Strandqvist]

I've added a feature strzcpy to make it easier to not do wrong
when you use the function strncpy.
By not have to add a guaranteed trailing null character:
  strncpy(to, src, c);
  to[c - 1] = '\0';


This arose after a discussion with Dan Carpenter:

https://lkml.org/lkml/2014/9/15/74

And I was thinking of making it with the return value corresponding
to strlen, but could not make any neat/optimal solution.
But if we are to add this maybe it's worth thinking about whether
we can use the return value to something sensible.
