_KPOSIX_PRIORITY_SCHEDULING options to work. Changes: Change all "posix4" to "p1003_1b". Misnamed files are left as "posix4" until I'm told if I can simply delete them and add new ones; Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux; Add man pages for _POSIX_PRIORITY_SCHEDULING system calls; Add options to LINT; Minor fixes to P1003_1B code during testing.
