candidate sched.h and sys/sched.h for review

[Joel Sherrill]

Next try.  I am starting a build with this now so there
might be problems.

Corinna.. SCHED_SPORADIC is now 4.  My concern is
with these constants is that they are sometimes used
in language bindings and we would have to propagate that.
If you don't mind, once this rework is in, I will address
getting us in sync on the other values.

How does it look now?
