The ControlInfoMap and V4L2ControlInfoMap classes are very similar, with the latter adding convenience accessors based on numerical IDs for the former, as well as a cached idmap. Both features can be useful for ControlInfoMap in the context of serialisation, and merging the two classes will further simplify the IPA API. Import all the features of V4L2ControlInfoMap into ControlInfoMap, turning the latter into a real class. A few new constructors and assignment operators are added for completeness.
