{set,fill}_{,fp,db}regs() fixup:

 - Add dummy {set,fill}_dbregs() on architectures that don't have them.

 - KSEfy the powerpc versions (struct proc -> struct thread).

 - Some architectures had the prototypes in md_var.h, some in reg.h, and
   some in both; for consistency, move them to reg.h on all platforms.

These functions aren't really MD (the implementation is MD, but the interface
is MI), so they should move to an MI header, but I haven't figured out which
one yet.

Run-tested on i386, build-tested on Alpha, untested on other platforms.

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!)

5596cfd09a * Fix exception handling so that it actually works. We can now handle
exceptions from both kernel and user mode.
* Fix context switching so that we can switch back to a proc which we
  switched away from (we were saving the state in the wrong place).
* Implement lazy switching of the high-fp state. This needs to be looked
  at again for SMP to cope with the case of a process migrating from one
  processor to another while it has the high-fp state.
* Make setregs() work properly. I still think this should be called
  cpu_exec() or something.
* Various other minor fixes.

With this lot, we can execve() /sbin/init and we get all the way up to its
first syscall. At that point, we stop because syscall handling is not done
yet.

8d9761debf Next round of fixes to the ia64 code. This includes simulated clock and
disk drivers along with a load of fixes to context switching, fork
handling and a load of other stuff I can't remember now. This takes us as
far as start_init() before it dies. I guess now I will have to finish off
the VM system and syscall handling :-).

1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
