Initiate deorbit burn sequence for sysctl CTL_USER MIB branch.
Use the correct constants directly from sysconf() rather than calling
sysctl() to tell us the (still compiled-in) value. Leave the CTL_POSIX1B
stuff alone for now (but I'd like to see this replaced with a single
structure returning all of the relevant information).

Implement all of the keys from 1003.1-2001 that we can. Ensure that
the build will break if someone redefines an option constant to zero
without implementing the necessary presence-detection logic here.

Don't bother asking the kernel about _SC_FSYNC; it's not optional.

A break after a return is useless.

Fix SCM ID's.

Add support for sysconf(_SC_NPROCESSORS_CONF) and sysconf(_SC_NPROCESSORS_ONLN).
This API is supported in SVR4.0MP, Solaris, Linux, AIX and Tru64 Unix.

2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE

defined in POSIX. These show up when:

_POSIX_SOURCE and _POSIX_C_SOURCE are not set or

POSIX.4 headers and sysctl variables. Nothing should change

Include sys/time.h, not sys/user.h.

Submitted by: "Marc G. Fournier" <scrappy@hub.org>

Add #include <sys/user.h>.

Minor cleanup, mostly unused vars and missing #includes.

Remove trailing whitespace.

Include <time.h> instead of <sys/time.h> to get CLK_TCK. Including
<sys/time.h> works because <sys/time.h> includes <time.h> if KERNEL

I've no idea if this is the right behavior for the library, but this
at least fixes the build, and matches what seems to be alfred's intent
in the commit message for 1.19.

Rework the sysconf(3) interaction with aio:

sysconf.c:
Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0'
return value from the kernel sysctl.

vfs_aio.c:
Make aio reset its configuration parameters to -1 after unloading
instead of 0.

posix4_mib.c:
Initialize the aio configuration parameters to -1
to indicate that it is not loaded.
Add a facility (p31b_iscfg()) to determine if a posix4 facility has been
initialized to avoid having to re-order the SYSINITs.
Use p31b_iscfg() to determine if aio has had a chance to run yet which
is likely if it is compiled into the kernel and avoid spamming its
values.
Introduce a macro P31B_VALID() instead of doing the same comparison over
and over.

Prototype p31b_iscfg().

_SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX

Without these adjustments the values returned are -1 even when the
aio side of the kernel returns '0' for them which is incorrect.
