* make everything prettier (KNF) * OpenSMTPD is taken as an example here for prototypes * grooming these was a lot of hard work...

* fix hash algorithm...thank you to the chinese who made me aware there was a problem, and sorry for the limitation on service!

* add a defineable ratelimit between 1 and 127 packets per second per a 16 bit hash of IP (IPv4 and IPv6). * example configuration is in example8.conf where it's 6 packets per second. * this will add memory to the order of 65536 * (((pps * 2) * 8) + 1) so 12 pps would be 12648448 bytes of shared memory added... * also there is a race that I know about in the adding of a packet to the backlog, but I don't use the -n flag in production so it's limited compiles and tested on OpenBSD 5.5
