For headers we control, which is most of the ones in the patch, we
should just fix them. I'll do it...

(that means bm.h, ifaddrs.h, kvm.h, link_aout.h, login_cap.h, 
nsswitch.h, AFAIK.)

res_update.h, resolv.h, arpa/inet.h, and arpa/nameser.h are in both
src/include and src/external/bsd/libbind; it appears that for all of
them our version in src/include is the one we're using, and that there
are already substantial diffs relative to the ones in libbind;
therefore I see no reason not to also update the ones in src/include,
but I'll hold off for the moment in case someone wants to argue to the
contrary.
