emacs: Generalize buffer naming.
* emacs/guix-base.el (guix-buffer-name): New procedure. (guix-buffer-define-interface): Make ':buffer-name' a required keyword. (guix-update-after-operation, guix-buffer-name-function) (guix-buffer-name-simple, guix-buffer-name-default, guix-buffer-name) (guix-buffer-p, guix-buffers, guix-update-buffer) (guix-update-buffers-maybe-after-operation): Adjust, move and rename to... * emacs/guix-ui.el (guix-ui-update-after-operation) (guix-ui-buffer-name-function, guix-ui-buffer-name-simple) (guix-ui-buffer-name-default, guix-ui-buffer-name) (guix-ui-buffer?, guix-ui-buffers, guix-ui-update-buffer) (guix-ui-update-buffers-after-operation): ... this. (guix-ui-define-interface): Generate 'guix-ENTRY-TYPE-BUFFER-TYPE-buffer-name' procedure and pass it as ':buffer-name' argument. (guix-ui): New custom group. * emacs/guix-info.el: Specify ':buffer-name' for the defined interfaces. * emacs/guix-list.el: Likewise. * doc/emacs.texi (Emacs Appearance): Adjust accordingly.
