Add real sched.h

Browse Source 
It is required by IEEE Std 1003.1-2008 AKA POSIX.

Put some Linux compatibility stuff under BSD_VISIBLE namespace, in
particular, sys/cpuset.h definitions.  Also, if user really want
Linux compatibility, she can request cpu_set_t typedef with
_WITH_CPU_SET_T define.
