heap gap from max data size. nothing else changes yet. ok deraadt

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

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.

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.
OK blambert@
Agreed by many.

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.

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.

type of all variables to daddr64_t. this includes the APIs for XXsize()
and XXdump(), all range checks inside bio drivers, internal variables
for disklabel handling, and even uvm's swap offsets. re-read numerous
times by otto, miod, krw, thib to look for errors

it's a good idea to use atomic.h operations on it. This mechanic
change updates all bit operations on p_flag to atomic_{set,clear}bits_int.
Only exception is that P_OWEUPC is set by MI code before calling
need_proftick and it's automatically cleared by ADDUPC. There's
no reason for MD handling of that flag since everyone handles it the
same way.

argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.

(but still implemented via setres[ug]id(2)). Basically this just
moves them from COMPAT_43 into kern_prot.c. Also fixes a typo in my
old implementation. The userland portion will follow in a few days.

on the returned file, do the FREF inside getvnode so that people can't
get away with avoiding FREF and FRELE.

the same semantics as NetBSD anyway, so it's good to avoid name collissions.
- Always fdremove before freeing the file, not the other way around.
- falloc FREFs the file.
- have FILE_SET_MATURE FRELE the file (It feels like a good ortogonality to
falloc FREFing the file).
- Use closef as much as possible instead of ffree in error paths of
falloc:ing functions. closef is much more careful with the fd and can
deal with the fd being forcibly closed by dup2. Also try to avoid
manually calling *fo_close when closef can do that for us (this makes
some error paths mroe complicated (sys_socketpair and sys_pipe), but
others become simpler (sys_open)).

This time we're getting rid of KERN_* and VM_PAGER_* error codes and
use errnos instead.
