One of the arguments is that programmers should be concerned when a string
buffer oveflow, and so my point is that that strlcpy make it easier to check
overflow and strcpy_s refuse to copy the string at all if the buffer
Regardless it is not part of a standard yet, so it may not be a good idea to
add it to glibc.
