string_split, string_compare, time_to_string, canonicalize_string should
probably all go in here. Also, calling it string_util or something is a bit
better than just "util", and why isn't it in the util/ directory?

[please use gerrit instead, 2014/03/24 22:56:29]

Done, except for canonicalize_string, because that's a class, not a function.
