Implemented aStrndup()

- aStrndup() behaves similarly to the POSIX function strdup(). It
  allocates sufficient memory for a copy of the passed string, copies
  it, and returns a pointer to the copy. A maximum number of characters
  is copied (and a NUL terminator is always appended after the end).
