network - Completely revamp the netisr / dispatch code
* All netisrs are dispatched MPSAFE (followup in later commits)
* Centralize the protocol threads. There is now just one thread
per cpu managed by the netisr code. No more separate tcp/udp threads
on each cpu.
* Make the mbuf M_HASH/m_pkthdr.hash mechanic the central routing
mechanic for netmsgs.
* Remove the netisr ip_mport and pktinfo_portfn stuff and replace with a
cpufn function which handles M_HASH/m_pkthdr.hash when M_HASH is not
already set.
* Seriously clean up the packet input paths. Adjust ether_input_chain() and
friends to not have to adjust the mbuf forwards and backwards, instead
pass a header offset to the ni_cpufn function. The ip pullup and other
related code will use the offset to determine where the ip header is
within the packet.
