  commit 0ab8ed18a6fe98bfc82705b0f041fbf2a8ca5b60

      trace: switch to modular code generation for sub-directories
      
      Introduce rules in the top level Makefile that are able to generate
      trace.[ch] files in every subdirectory which has a trace-events file.
      
      The top level directory is handled specially, so instead of creating
      trace.h, it creates trace-root.h. This allows sub-directories to
      include the top level trace-root.h file, without ambiguity wrt to
      the trace.g file in the current sub-dir.
