'pfctl -o' ruleset optimizer that doesnt change the meaning of the final ruleset

- remove identical and subsetted rules
- when advantageous merge rules w/ similar addresses into a table and one rule
- re-order rules to improve skip step performance (can do better w/ kernel mods)
- 'pfctl -oo' will load the currently running ruleset and use it as a profile
to direct the optimization of quicked rules
