Merge #623

623: WIP: module id is not def id r=matklad a=matklad

This achieves two things:

* makes module_tree & item_map per crate, not per source_root
* begins the refactoring to remove universal `DefId` in favor of having separate ids for each kind of `Def`. Currently, only modules get a differnt ID though.
