1a291e0cd4 Add new functions fill_fpregs() and set_fpregs(), like fill_regs()
and set_regs() but for the floating point register state.  The code
is stolen from procfs_machdep.c, and moved out of there into
machdep.c.

These functions are needed for generating ELF core dumps.

7b3c84247b Preserve %fs and %gs across context switches. This has a relatively low
cost since it is only done in cpu_switch(), not for every exception.
The extra state is kept in the pcb, and handled much like the npx state,
with similar deficiencies (the state is not preserved across signal
handlers, and error handling loses state).

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

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.

c277f99332 Declare a real `struct fpreg' to prepare for implementing reading and
writing of FP regs for procfs.

abd358cd49 apm_bios.h: removed the equiv-stuff. Not needed now that the kernel module
works correctly.

clock.h & reg.h: prototypes.

The following patch adds the addr argument to signal handlers.

The kernel with the patch is no more and no less in compliance or in
violation of POSIX and ANSI C than the kernel before the patch.

The added functionality this addr argument provides is quite useful.  It
enables an entire class of algorithms which use mprotect to trace memory
references.  Beside garbage collectors, I have heard of this technique being
applied to debuggers and profilers.  The only benchmarking I've performed is
using akcl to compile maxima:  without the kernel patch, it takes 7 hours to
compile maxima, while with stratified garbage collection, it only takes 50
minutes.

Basically, I can't think of a reason not to add the addr argument and there
is a compelling need for it.

If you find the patch acceptable, please let me know so I can send my
FreeBSD akcl config files to wfs for inclusion in the core akcl release.
The old 386BSD config files there won't work on either NetBSD or FreeBSD.

...also, fixed up the syscall args to make GCC happy.

6e393973f5 Made all header files idempotent and moved incorrect common data from
headers into a related source file.  Added cons.h as first step towards
moving i386/i386/cons.h to machine/cons.h where it belongs.
