Michael Tuexen a92d501617 Improve the handling of cookie life times. 
The staleness reported in an error cause is in us, not ms.
Enforce limits on the life time via sysct; and socket options
consistently. Update the description of the sysctl variable to
use the right unit. Also do some minor cleanups.
This also fixes an interger overflow issue if the peer can
modify the cookie. This was reported by Felix Weinrank by fuzz testing
the userland stack and in

* Blocking I/O is enabled on any TCP type socket by default. For the UDP
* model if this is turned on then the socket buffer is shared for send
* resources amongst all associations. The default for the UDP model is that
* is SS_NBIO is set. Which means all associations have a separate send
* limit BUT they will NOT ever BLOCK instead you will get an error back
* EAGAIN if you try to send too much. If you want the blocking semantics you
* set this option at the cost of sharing one socket send buffer size amongst
* all associations. Peeled off sockets turn this option off and block. But
* since both TCP and peeled off sockets have only one assoc per socket this
* is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
* model OR peeled off UDP model, but we do allow you to do so. You just use
* the normal syscall to toggle SS_NBIO the way you want.
