when not doing CLONE_THREAD, like we did before, instead of treating
it as an error. This unbreaks Opera running in linux compat.
Also, Linux completely ignores CLONE_DETACHED, so do that too, and
consistently refer to the flags in comment via their Linux names
without trying to abbreviate them further.
Problem found and fix confirmed by sturm@

and catching FORK_THREAD when RTHREADS wasn't compiled in. Simplify
sys_rfork() based on that.
Flesh out the Linux clone support with more flags, but stricter
checks for missing support or bad combos. Still not enough for
NPTL to work, mind you.

and hacking on it. Since then, some of the details of finishing a
wait have changed (p_exitsig handling), so factor out the common
bit into into proc_finish_wait() and have both sys_wait4() and
svr4_sys_waitsys() call that to kill the divergence.

Prompted by parfait noticing overflows in ibcs2/svr4 which
are now changed to being NSIG sized like the others as
suggested by tedu.

correctly, usually yielding the right value on 32 bit machines because
sizeof int == sizeof pointer.

which is exactly what the macro does.
Macro's that are nothing more then:
#define FUNCTION(arg) function(arg)
are almost always pointless and should go away.

POSIX 1003.1-2008, with compatibility macros for the names used in
previous version of OpenBSD. Update all the references in the
kernel to use the new, standard member names.

it might be needed later -- before calling pfind(), so that enterpgrp()
can operate without sleeping

- file descriptor table becomes the owner of the lock instead of the proc.
- When grabbing the lock, we check if the fd hasn't changed under our
feet, this is more or less impossible to solve without a hack like
this. I've banged my head against the wall, I figured out a solution,
but implementing it correctly would cost me 12 gray hairs. Screw it,
this is ugly, but it works.
- Wait until usecount drains before releasing the posix lock in closef.
- Add missing FREF/FRELE to sys_flock
- keep the pid in the flock struct instead of abusing the fact that we
used to use the proc as the lock owner.
Pointed out by and discussed with Al Viro, big thanks.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

find their interpreter, as the linux ld.so name is unique and not likely to
be found in another /emul/foo hierarchy; allows Opera to run again. Noticed

fold sys_shmat1() back into sys_shmat(), instead add flag for shmget(2)
to specify that later shmat(2) for the shared memory segment should succeed
even if the segment would be marked removed; use this to implement the
Linux-compatible semantics of shmat(2)
this fixes current opera with shm
