Replace remaining Tokenize calls to SplitString

SplitString is now more general and does the job of Tokenize with specific parameters.

The biggest change is in time_util.cc where the old return pattern better matched how the code was structured. With the new style the conditionals are more nested.

Some simple cases were changed to StringPieces when copies were not required.
