Remove mentions of CLONE_PID and CLONE_STOPPED

CLONE_PID was removed in Linux 2.5.15 and recycled for
CLONE_PIDFD since Linux 5.2.
CLONE_STOPPED was removed in Linux 2.6.38 and recycled
for CLONE_NEWCGROUP since Linux 4.6.

Change the sched_*() functions to return -1 and set errno to ENOSYS
(per the standard) instead of returning ENOSYS.  Noted by Ian Zagorskih

Change the sched_*() functions to return -1 and set errno to ENOSYS
(per the standard) instead of returning ENOSYS.  Noted by Ian Zagorskih
in PR kern/30970.

de-__P -- the hack is long since useless. Discussed with christos,
matt, kleink, others. Approved by christos.

__libc_thr_yield() signature now matches sched_yield().
Pointed out by Kouichirou Hiratsuka on current-users.

Use CPP macros to cause many libpthread functions used by applications
to be transformed into the do-nothing-when-libpthread-isn't-linked libc
stub names. This will permit library code that uses <pthread.h> and pthread
functions "defensively" to not need to link against libpthread and not need
to be patched to the threadlib.h API.

prototype must not have variable name

Add a new feature-test macro, _NETBSD_SOURCE.  If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

Merge the nathanw_sa branch.

Move sched_param and policies into sys/sched.h, and give SCHED_OTHER
the value 0.

Define SCHED_OTHER and remove SCHED_DEFAULT.

Pull in sys/cdefs.h

Make this safe for C++.

_LIB_PTHREAD_SCHED_H -> _SCHED_H_

It's back with the pthreads bits.

sched.h is now part of the pthread library

file sched.h was added on branch nathanw_sa on 2001-10-08 20:13:46 +0000

A <sched.h> file, which provides the clone(2) prototypes, in order
to be compatible with Linux.
