Here is a new series of 2 patches: the first one is unchanged (only
rebased to master) and the second one introduces the extensions field
and documents it. I added an example in the documentation.

Extension packages still have to be visible for users to list them in
the new field, so it seems hard to hide them at the same time :) I
agree it would make sense to be able to list all such extensions, and
so is listing extensions to other packages. Maybe we can think of a
generic mechanism for that?
