Complete the code that I have started. Three goals:

 - Use package.el to build (compile, generate autoloads) packages in
   during the build
 - Use package.el to initialize and load these during startup
 - Support testing of these packages during build.

With a secondary aim of:

 - Enable a built emacs to build and test all packages in ELPA whether
   they are core/tarball or not.

Erm, don't do this.

Or write something such as you have been talking about, by copying bits
of ELPA into core, otherwise (presumably) leaving the build alone.

I presume John means what I have discussed above.

It's obviously difficult for me to think of better ways of achieving
this than my current proposal. There are probably worse ways of
achieving it, I am sure.
