- Switch to our own simpler token bucket, since x/time/rate is missing
necessary stuff (can't provide your own time func; can't check the
current bucket contents) and it's overkill anyway.
- Add tests that actually include advancing time.
- Don't remove the rate limit on a message until there's enough room to
print at least two more of them. When we do, we'll also print how
many we dropped, as a contextual reminder that some were previously
lost. (This is more like how the Linux kernel does it.)
- Reformat the [RATE LIMITED] messages to be shorter, and to not
corrupt original message. Instead, we print the message, then print
its format string.
- Use %q instead of \"%s\", for more accurate parsing later, if the
format string contained quotes.
