Finish _POSIX_PRIORITY_SCHEDULING. Needs P1003_1B and

_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.

- * March 1, 1998: Details from here on change and this header file
- * is volatile.
- *
- * Locally I've got PRIORITY SCHEDULING
- * set as a system call available only to root 
- * and I'm still using a pseudo device to gate everything else.
- *
- * This interface vectors us into the kernel through a
- * POSIX4 pseudo device with some user privilege authorization along
- * the way.
- *
- * XXX I'm going with option 3.
- *
- * This has drawbacks from the point of view of ktrace.  There
- * are (at least) three ways to do this:
- *
- * 1. As it is being done, which is bad for ktrace and is hokey
- *    but is easy to extend during development;
- * 2. Add a system call for every POSIX4 entry point, which
- *    will result in many more system calls (on the order of 64)
- * 3. Add a system call for each POSIX4 option, which is a bit more
- *    useful for ktrace and will add only about 14 new system calls.
- *

+ * LKM'd.  References "syscall_not_present".
