f51c1e897d 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().

c7047e5204 Change the way support for asynchronous I/O is indicated to applications
to conform to 1003.1-2001.  Make it possible for applications to actually
tell whether or not asynchronous I/O is supported.

Since FreeBSD's aio implementation works on all descriptor types, don't
call down into file or vnode ops when [f]pathconf() is asked about
_PC_ASYNC_IO; this avoids the need for every file and vnode op to know about
it.

6d5dec35b7 Add the rest of the kernel support for the sem_ API in kern/uipc_sem.c.
Option 'P1003_1B_SEMAPHORES' to compile them in, or load the "sem" module
to activate them.

Have kern/makesyscalls.sh emit an include for sys/_semaphore.h into sysproto.h
to pull in the typedef for semid_t.

Add the syscalls to the syscall table as module stubs.

4505fec89e Add $FreeBSD$.
Initialize the POSIX.1b sysconf information appropriately for
non-optional kernel functions.

ce02431ffa * Change sysctl from using linker_set to construct its tree using SLISTs.
This makes it possible to change the sysctl tree at runtime.

* Change KLD to find and register any sysctl nodes contained in the loaded
  file and to unregister them when the file is unloaded.

8a6472b723 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.

POSIX.4 headers and sysctl variables.  Nothing should change
unless POSIX4 is defined or _POSIX_VERSION is set to 199309.
