OK, I'll use a separate lib/libkern/kernel subdirectory for this.
(But I'll leave the other routines where they are for now).
I have some additional routines for this kernel library directory, namely
C-coded versions of {f,s}u[i]{byte,[s]word} routines, that could be used
if some port doesn't have assembly coded versions in locore.s.
Note, that the su[i][s]word routines in at least the 386 locore.s are
incorrect. They don't work correctly if the word laps over a page boundary.
Probably, the addupc routine should be included here, too (as it has the same
problem on the 386), but I don't have a working version yet.
