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.
posix4.h:
Prototype p31b_iscfg().
