format_template attribute

I've been sitting on this for a while and would like to get some
comments; apologies if this is inappropriate for this list. It's also
a lot of code for not finding any bugs in the current kernel, but I
guess that's good thing. It's on top of Emese's v2 infrastructure. It
probably won't build with all gccs; it works for me with gcc 4.9.
