checkpoint/restart

[Kip Macy]

Sorry, I thought I ifdefed out all the references with DO_UPCALL.



I added (locally) two fields to sigact to store references to the
freeze/thaw upcalls. I was hoping to avoid making any changes to the
kernel, but I don't see any clean way around this. When I switch to
DragonFly in half an hour, I'll send out a patch.
