Subject: Add L2 L3 Cache lookup by default.

 - Import infrastructure for caching flows as a means of accelerating L3 and L2 lookups
   as well as providing stateful load balancing when used with RADIX_MPATH.
 - Currently compiled in to i386 and amd64 but disabled by default, it can be enabled at
   runtime with 'sysctl net.inet.flowtable.enable=1'.

 - Embedded users can remove it entirely from the kernel by adding 'nooption FLOWTABLE' to
   their kernel config files.

 - A minimal hookup will be added to ip_output in a subsequent commit. I would like to see
   more review before bringing in changes that require more churn.
