Former-commit-id: 7702c606ca5f78a3ecf78eb747e2da9af4ddbb0e

Updating packages to use the `extends<...>` pattern.


Former-commit-id: 30100ba4e30bc4b80e3f2a338a35cdc7dc9ae902

Directly declaring the `InterfaceID` and the `interfaceID` method
is deprecated. Replacing it with the recommended `DeclareInterface`
syntax which creates both.

Also tidied whitespace in the updates files.
