Doing this in a sane way requires a fairly large directory reorg. This
is something that I am going to do once we have SCM rename support and
don't really want to begin on until then.

(Well, "requires", in the sense that we could create src/sys/include
and put some stuff there without doing the full cleanup to move
src/sys/sys to src/sys/include/sys, or stop sharing sys/*.h directly
between kernel and userland. But I don't think this is a good idea --
the kernel include namespace is confusing enough as it is.)
