Make a root 'guix-buffer-define-interface' macro. It should generate a
common code for any type of interface. Inherit 'guix-info-define-interface'
and 'guix-list-define-interface' from it. They should provide a general
'info'/'list' interface for any data. Finally, make
'guix-ui-define-interface' for the common code for interfaces to Guix
packages and generations, and inherit 'guix-ui-info-define-interface' and
'guix-ui-list-define-interface' from it.
