4f8efb8b8e Implementation of posix-style clock_* and nanosleep syscalls as implemented 
in NetBSD.  The core of settimeofday() is moved to a seperate static
function settime() which both clock_settime() and settimeofday() call.

Note that I picked up the securelevel > 1 check from NetBSD that prevents
the clock being set backwards in high securelevel mode (this was a hole
that allowed resetting of inode access timestamps to arbitary values)

Obtained from:  mostly from NetBSD, but the settime() function is from
our gettimeofday(), some tweaks by me.

74665b766b Define entries for the posix-style clock/timer syscalls including 
nanosleep().  Also, note some syscall conflicts with other systems and
indicate slots tagged for use with other syscalls some day.

9d89eb4a5f Don't allow access to illegal addresses in /dev/kmem to panic kernel 
(eg: above 0xffc00000).  Programs using /dev/kmem are implicitly racing
the kernel, and can get right up high in memory.  I've been running
these for some time now, but with printfs.  It's saved two panics at
least that I can remember.

95d8f20aba clean up forked child creation. This is simplified also by having 
md_regs being struct trapframe *.  Do a npxsave() if needed and copy the
pcb rather than use the increasingly defunct savectx().  Copy %edi and
%ebp explicitly.

Submitted by: bde

XXX npxproc could be declared in npx.h so the externs with smp fruit
are not needed.

31ae3c21c9 md_regs is struct trapframe * now, rather than int [] 
Remove TF_REGP() macro and use.  The original reason (address space
problems due to having UPAGES in mapped into user space) is gone.  It
looks cleaner without it.

b0e8461f06 This is the kernel linker. To use it, you will first need to apply 
the patches in freefall:/home/dfr/ld.diffs to your ld sources and set
BINFORMAT to aoutkld when linking the kernel.

Library changes and userland utilities will appear in a later commit.

a41ee117b0 Now that we have replaced video-related block copy calls with 
sc_bcopy(), which is generic_bcopy() in reality, there is no point in
retaining bcopyw() calls in the source code.
