kernel: Fix nano_internal.h inclusion

_Swap() is defined in nano_internal.h.  Everything calls _Swap().
Pretty much nothing that called _Swap() included nano_internal.h,
expecting it to be picked up automatically through other headers (as
it happened, from the kernel arch-specific include file).  A new
_Swap() is going to need some other symbols in the inline definition,
so I needed to break that cycle.  Now nothing sees _Swap() defined
anymore.  Put nano_internal.h everywhere it's needed.

Our kernel includes remain a big awful yucky mess.  This makes things
more correct but no less ugly.  Needs cleanup.
