Refactoring of the build system.

    - Remove unused files for generating LIDs.
    - Reduce the overall verbosity of the build.
    - Separate 'config.mk' into a number of smaller, topic-centric
      files and comment better.
    - Generalize the 'passes' concept and added an IMAGES pass.
    - Deprecate most "magic" make variables like EXTRAFOO.
    - Overall performance improvements.

    I've tried to reduce the impact of these changes on component-level
    makefiles.  There will be follow-up commit(s) to improve those and
    decrease the verbosity of some component-owned commands.
