The one thing `log` can still do is polymorphically log anything,
but debug!, etc. require a format string. With this patch
you can equivalently write `debug!(foo)` or `debug!("%?", foo)`

I'm doing this because I was trying to remove `log` (replacing it with nothing, at least temporarily), but there are a number of logging statements that just want to print an arbitrary value and don't care about the format string.
I'm not entirely convinced this is a good change, since it overloads the implementation of these macros and makes their usage slightly more nuanced.
