Stop sharing the double-fault stack.
Merge the TSS structures into one single cpu_tss structure, and
allocate it dynamically.

Remove undocumented hack.
--
Switch to the temporary stack right away when booted via multiboot. GRUB
happens to give a correct stack, but it is not guaranteed by the spec. This
temporary stack will be reset later, which is fine.
Fixes PR/50245.
--
Pfff, use %ss and not %ds. The latter is controlled by userland, the former
contains the kernel value (flat); FreeBSD fixed this too a few weeks ago.
As I said earlier, this dtrace code is complete bullshit.
--
Don't allow userland to create 286/386 call gates anymore - they are not
used by Wine. While here, don't allow it to overwrite the static entries
either, don't allow unknown entry types, remove LDT_DEBUG, and style.

Pull up following revision(s) (requested by maxv in ticket #88):
	sys/arch/amd64/amd64/locore.S: revision 1.124
	sys/arch/i386/i386/locore.S: revision 1.146
	sys/arch/i386/i386/machdep.c: revision 1.783
	sys/arch/i386/i386/trap.c: revision 1.288
Remove the osyscall call gate on i386, and emulate it. There is a one-
instruction race in it that could panic the kernel.

Fix these comments, we probably won't want to keep them up to date.
