Summary:
This just moves things around. So native and pure Python modules are split to
different Python packages. This makes it possible to use the standard zip
importer without hacks (ex. `hgdemandimport/embeddedimport`).
This diff is mostly about moving things. While `make local` still works,
it does break nupkg build, which will be fixed in a later diff.
