Part 3 of scalability improvement: provide lock-free implementation of

ad_page_contract_filter_rules. If nothing bad shows up, the

underlaying nsv-arrays can be removed completely.

If one looks at the top 10 nsv mutex locks of a rather busy site

(nsd running for 3 days), one can see the ad_page_contract_filters

and ad_page_contract_filter_rules belong to the most frequent

mutex locks, which can be avoided at completely. These two

arrays make up of nearly 40% of the top 10 nsv locks.
