    Add real sched.h
    
    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.
