Windows search protocol client

Windows search protocol client

look away for the moment (unless you really want to look :-)) and... if you are really interested then that is welcome too!! Mostly the merge request is here to help focus my mind on it (I do hope it wont too long for it to become ready for review)

Right now this really is WIP I'm trying to get patches in shape for a simple WSP client. I've made quite a few changes here from the orig patches I worked on (reorganised them alot, tried to simplify them) One of the biggest changes I've made is to remove the idl hacks, this makes life a little more difficult for the implementation but that hack allows recursive structures which are potentially dangerous. Additionally I am probably going to change how the properties are handled (currently in this patch set some csv(s) are used to generate code that describes the properties) it probably makes more sense to generate the properties on the fly from the metadata (or csv, json file or whatever) that at least would easily allow new property support without recompile
