Ah! Yes, very cool. Most callbacks could be converted to the new timer
callback pretty easily. Some, though, pass non-pointer data in the
"data" argument. Those can likely be moved to somewhere else, though.
I think it should be possible to just perform all the conversions.

Regardless, getting rid of init_timer*() and eliminating the
open-coded callback assignments should help. I'll keep grinding on
