kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out

avoid twisted indirected includes for existing users.

The integer exponentiation is used in few places and might be used in
the future by other call sites. Move it to wider use.
