amd64/i386/sparc64 kernels.

This allows us the unmap the initial part of the stack, such that it can't
be used as a staging area for ROP (or other) attacks.

objective: vnode.h doesn't include uvm_extern.h anymore.
followup changes: include uvm_extern.h or lock.h where necessary.

after discussions with beck deraadt kettenis.

Tweak the handling of ktrace EMUL when changing ktracing: only
generate one per process (not one per thread) and pass the correct
proc pointer down to the VFS layer. Permit generating of NAMI and
CSW records inside ktrace(2) itself.

The non-cookie path was probably always broken and never used.
The file descriptor offset was never updated after a read so glibc and
other syscall consumers would end-up in an infinite loop.
Tested with the syscalls regression suite from IBM and with opera.

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.
Much assistance in fixing userland issues from deraadt@ and tedu@

problem has been tracked down. This fixes the sharing of the signal
handling state: shared bits go in sigacts, per-rthread bits goes in
struct proc.

until they're zombies and then send them signals (for intr mounts). Until
that is untangled, the sigacts change is unsafe. sthen@ was the victim

be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves
to struct sigacts, wihle stuff that should be per rthread (ps_oldmask,
SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping
state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread
until our locking around coredumping is better.
Oh, and remove the old SunOS-compat ps_usertramp member.

in libkvm with the stable-ABI versions that are currently named
KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols
will continue to be supported for a few releases.

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.

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.

decide which files must be pulled into the kernel. Also conditionalize
the pulling of those files based on the COMPAT_* options.
