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.

+# DEFAULT_PASSES are what get run when you do a 'make' or 'make all'.  The
+# order of the passes in the variable define an ordering.
+#
+# OTHER_PASSES are special passes that get triggered by 'make NAME_PASS'.
+# Sometimes these have a shortcut, like 'make name'.  The content for these
+# are in their own special name.rules.mk.
