These changes are based upon something I brought up the other day,
namely that we do a full FIB lookup just to find whether a particular
unicast ipv4 address is attached to an interface.
Like ipv6, I added an RCU/RTNL protected hash table and reimplemented
__ip_dev_find() in terms of it.
These patches apply both with and without the route cache deletion
patch applied, but with the route cache removal applied the udpflood
test gets faster by ~13 seconds:
real 2m57.500s
user 0m10.640s
sys 2m46.910s
We can probably use this new table for other things as well.
