* add `pstrcpy` and `pstrcat` to string.c2i as safer alternatives for `strcpy` and `strcat`. * use `snprintf` instead of `sprintf` * use `pstrcpy` and `pstrcat` instead of `strcpy` and `strcat` * use `elemsof` instead of `sizeof` for array lengths * fix `strlcpy` and `strlcat` for conformity with BSD semantics. `pstrcpy` and `pstrcat` argument order and semantics are more convenient for readability and efficiency.
