[PATCH v2] lib: string.c: Added a funktion function strzcpy

[Rickard Strandqvist]

I've added a strzcpy to make it easier to not do wrong
when you use the function strncpy.

Often one needs the zero padding, but must still have a
guaranteed zero character terminat.
Then you end up writing code like this:
  strncpy(to, src, sizeof(to));
  to[sizeof(to) - 1] = '\0';

This is solved with strzcpy.
