Drop the current random timestamps and the current ISN generation
code and replace both with a RFC1948 based method, so TCP clients
now have monotonic ISN/timestamps. The server side uses completely
random ISN/timestamps and does time-wait recycling (on port reuse).
ok djm@, mcbride@; thanks to lots of testers
