Realtime priority scheduling support.

Browse Source 
Added "sys/rtprio.h" with the used defines.
    Added rtprio(2) - the kernel interface.                  init_sysent.c,
                                                             kern_resource.c
                                                             syscalls.master
    Added 32 new runqueues (rtqs), with initialization.      kern_proc.c
                                                             kern_synch.c
    Realtime processes do not change nice/priority           kern_synch.c
    Added a column "rt" to ddb's ps (#ifdef RTPRIO_DEBUG)    kern_synch.c
    Realtime priorities are enherited through fork().        kern_fork.c
    Init (and children) NOT run as realtime process.         init_main.c
