Merge #968

968: Macro aware name resoltion r=matklad a=matklad

The first commit lays the ground work for new name resolution, including

* extracting position-indendent items from parse trees
* walking the tree of modules
* old-style macro_rules resolve

cc @pnkfelix: this looks like an API name resolution should interact with.
