New safe action to add rewrite rules on

Currently I don't believe it's possible to meet the following two criteria:
- Not flush rewrite rules on every page load
- Ensure that you always have your rewrite rules available
The problem arises when Plugin A has not yet added it's rewrite rules, but Plugin B calls flush_rewrite_rules. Plugin A is a good citizen, and doesn't call flush_rewrite_rules unless it needs to and so now it's rewrite rules are no longer present. (See http://wordpress.stackexchange.com/questions/26029/when-to-call-add-rewrite-rule-for-safety for more.)
Westi suggested that hooks on delete_option and get_option of 'rewrite_rules' might work. This covers almost all situations, except the one where permalinks are off and then get turned on again when neither the delete_option or get_option actions/filters are fired.
Devs could hook the new action for their add_rewrite_rule calls, and use their own methodology to determine when to call flush_rewrite_rules.
