Split out aare_rules which are used to encapsulate creating the dfa

Split out the aare_rule bits that encapsulate the convertion of apparmor
rules into the final compressed dfa.

This patch will not compile because of the it needs hfa to export an interface
but hfa is going to be split so just delay until hfa and transtable are
split and they can each export their own interface.
