-replace user object/handle manager with the one from wine. its simpler, faster and more correct.

Browse source 
-convert dozens of functions to take pointers as args, not handles
-attempt to simplify/correct refcounting
-remove much useless refcounting
-make callout refcounts auto undoable (ei. if the thread crash in umode during callback)
-misc formatting/naming changes
