* Some values changed in POSIX.1-2001; provide the former value if a program
requests compliance to an earlier version of POSIX. [1]
* Add missing _POSIX_CLOCKRES_MIN constant. This is a maximum value but
otherwise works the same as the minimum values.

All the "Minimum Values" (POSIX.1-2008 XBD 13 Headers <limits.h>) are now
correct. These should all be exactly as they are in the specification; the
possibly higher values we support are announced differently.

Implement new sysconf keys. Change the implenentation of
_SC_ASYNCHRONOUS_IO in preparation for the next set of changes.
Move some limits which had been in <sys/syslimits.h> to <limits.h> where
they belong. They had only ever been in syslimits.h to provide for the
kernel implementation of the CTL_USER MIB branch, which went away with
newsysctl years ago. (There is a #error in <sys/syslimits.h> which I
will downgrade in the next commit.)
and its associated constants. Implement _SC_IOV_MAX in the usual way.
Be a bit sloppy about the namespace question; this should get cleared up
in time for 5.0.

_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.
Changes to support building with _POSIX_SOURCE set to 199309L:
1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;
2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE
3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX. These show up when:
_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L
and vanish when:
_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.
4. Explain these in man 9 posix4;
5. Include _posix.h and conditionalize on new feature test.
