enum flags (ASICachePolicy etc) should be prefixed

[marcetcheverry]

The enums such as ASICachePolicy, it is always useful to always prefix your flags with the type,

so typedef enum ASICachePolicy { ASICachePolicyDefault, ASICachePolicyDoNotRead …}

this makes code completion much more useful, as I can just type ASICachePolicy and get all the possible flags without having to look at the docs. Notice that Apple does this in UIKit.
