44956c9863 Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.

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().

b565fb9e6f headers should not really include "opt_foo.h" (in this case opt_posix.h).
remove it from the header and add it to the files that require 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.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

9f79feec16 Fixed some type mismatches. p_retval[0] in struct proc has type
register_t, so pointers to it must be passed around as `register_t *',
not as `int *'.  The type mismatches were non-benign on alphas, but
the broken code is normally only configured by LINT.

adc5342c47 The system call stubs for the sched_* system calls can't be
optional.

The kernel will now link but the new system calls can't be LKM'd in
without the P1003_1B option - I will remove this option later.

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.

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.

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