so that the process-level stuff is to/from struct process and not
struct proc. This fixes a bunch of problem cases in rthreads.
Based on earlier work by blambert and myself, but mostly written
at c2k10.
Tested by many: deraadt, sthen, krw, ray, and in snapshots

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

this became an issue when krw@'s X build failed when he was testing
a change to dkio.h.

sysctl.h was reliant on this particular include, and many drivers included
sysctl.h unnecessarily. remove sysctl.h or add proc.h as needed.

do permit ptrace() of pid 1 and have inferiors() stop climbing if
it hits that.

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.

which is exactly what the macro does.
Macro's that are nothing more then:
#define FUNCTION(arg) function(arg)

- 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.
