parser: accept iterator of tokens instead of tokenizer function and program

This can simplify the interface of parse() function. Our tokenizer tends to
have optional arguments other than the message to be parsed.

Before this patch, the "lookup" argument existed only for the revset, and the
templater had to pack [program, start, end] to be passed to its tokenizer.
