Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

fb919e4d5a Undo part of the tangle of having sys/lock.h and sys/mutex.h included in
other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

cb226aaa62 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

473fbdbe96 Add a hack to emulator to emulat spx device for local X connections.
This is truly a hack.  The idea is taken from the Linux ibcs2 emulator.

To use this feature, you must use the option,
	options		SPX_HACK
in your config.

Also, in /compat/ibcs2/dev, you must do:

lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 X0R@ -> /dev/null
lrwxr-xr-x  1 root  wheel         7 Oct 15 22:20 nfsd@ -> socksys
lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 socksys@ -> /dev/null
crw-rw-rw-  1 root  wheel   41,   1 Oct 15 22:14 spx

Do NOT use old socksys driver as that has been removed.
This hack needs /compat/ibcs2/dev/spx to be any device that does NOT
exist/configured (so the now non-existant spx major/minor works fine).
When an open() is called, the error ENXIO is checked and then the
path is checked.  If spx open detected, then a unix socket is opened
to the hardcoded path "/tmp/.X11-unix/X0".

As the Linux hacker author mentioned, the real way would be to detect
the getmsg/putmsg through /dev/X0R and /dev/spx.  Until this true
solution is implemented (if ever), I think this hack is important
enough to be put into the tree, even though I don't like it dirtying
up my clean code (which is what #ifdef SPX_HACK is for).

9e03db613c Remove old files no longer needed.
Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code.  The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

 o  "clean" code, including strict prototyping.
 o  Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls.  Generation includes system tables, structure definitions,
and prototyping of function calls.
 o  ibcs2 emulator does not rely on any COMPAT_43 system calls.
 o  embedded socksys support
 o  ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
 o  alternate /emul/ibcs2 namespace searched first for files in ibcs2
system.  Usefull to keep sysv libraries, binaries in /emul/ibcs2.
 o  many other finer details and functions fixed or implemented.
