/* This function is similar to strncpy(). However it won't copy more
than N - 1 characters and makes sure that a '\0' is appended. With
N given as 0, nothing will happen. With DEST given as NULL, memory
will be allocated using xmalloc (i.e. if it runs out of core
the function terminates). Returns DES or a pointer to the
allocated memory.
