Add xstrtokenize to the dix.

Move tokenize out of the parser, make it a dix util function instead.
Splitting a string into multiple substrings is useful by other places, so
let's use it across the line. Future users include config/hal, config/udev
and of course the parser.

Example usage:
char **substrings = xstrtokenize(my_string, "\n");
