Title: Review: back off of tinyformat just a bit

Restore old-fashioned unsafe format() as "format_raw()", for those rare
times when you must have every last feature of printf, including those
that tinyformat doesn't handle (and are willing to trade type safety and
expandability to do it).

What do you know, we need this for Strutil::memformat and Strutil::timeintervalformat!

Which we didn't notice because we had no unit tests for them, which I also have
now added.
