ipv4 05/05: add sysctl to accept packets with local source addresses
commit 8ec1e0ebe26087bfc5c0394ada5feb5758014fc8

ipv4: add sysctl to accept packets with local source addresses
Change fib_validate_source() to accept packets with a local source address when
the "accept_local" sysctl is set for the incoming inet device. Combined with the
previous patches, this allows to communicate between multiple local interfaces
over the wire.
