I don't see an strndup() function in our libc.

While it seems like a cool function name, what's the point of having it?
If you know how much you want to copy, it's trivial to allocate a buffer
large enough and strlcpy() into it.  If you don't know how much you want
to copy, then strdup() is ok anyway :)
