* rename method
* move more logic from PathManager to PathCollectionEntry

* make trace logging "core-pushes" model, to a sink installed by the frontend. This sink can go straight to the disk without wasting memory if that's what the Trace Logger tool has selected; or the Trace Logger will buffer it if it needs to. Formerly, we had a "core-pushes-to-buffer" and "client-pulls-once-per-frame" which necessarily caused huge buffers no matter what was going on.
- IServiceProvider, BasicServiceProvider: Added compile-time unknown type versions of GetService and HasService.
- ToolManager: Added IsAvailable to test whether all dependencies for a tool are available.
