emacs: Generalize buffer interface.
Extract the code for defining buffer interface from "guix-base.el", generalize it and move to "guix-buffer.el". * emacs.am (ELFILES): Add "emacs/guix-buffer.el". * emacs/guix-base.el (guix-profile, guix-entries, guix-buffer-type) (guix-entry-type, guix-search-type, guix-search-vals, guix-set-vars) (guix-get-symbol, guix-show-entries, guix-get-show-entries) (guix-set-buffer, guix-history-call, guix-make-history-item) (guix-get-params-for-receiving): Remove. (guix-switch-to-buffer): Rename to 'guix-buffer-display' and move to "guix-buffer.el". (guix-get-entries): Rename to 'guix-ui-get-entries' and move to "guix-ui.el". (guix-buffer-data, guix-buffer-value, guix-buffer-param-title) (guix-buffer-name, guix-buffer-history-size) (guix-buffer-revert-confirm?, guix-buffer-map, guix-buffer-revert) (guix-buffer-after-redisplay-hook, guix-buffer-redisplay) (guix-buffer-redisplay-goto-button): Move to... * emacs/guix-buffer.el: ... here. New file. (guix-buffer-item): New variable. (guix-buffer-with-item, guix-buffer-with-current-item) (guix-buffer-define-current-item-accessor) (guix-buffer-define-current-item-accessors) (guix-buffer-define-current-args-accessor) (guix-buffer-define-current-args-accessors): New macros. (guix-buffer-get-entries, guix-buffer-mode-enable) (guix-buffer-mode-initialize, guix-buffer-insert-entries) (guix-buffer-show-entries-default, guix-buffer-show-entries) (guix-buffer-message, guix-buffer-history-item, guix-buffer-set) (guix-buffer-display-entries-current) (guix-buffer-get-display-entries-current) (guix-buffer-display-entries, guix-buffer-get-display-entries): New procedures. * emacs/guix-info.el: Adjust for the procedures renaming. (guix-info-define-interface): Add ':show-entries-function' keyword. * emacs/guix-list.el: Likewise. * emacs/guix-ui.el (guix-ui-define-interface): Generate 'guix-ENTRY-TYPE-BUFFER-TYPE-get-entries' procedure based on 'guix-ui-get-entries'. * emacs/guix.el (guix-get-show-packages, guix-get-show-generations): Adjust for the procedures renaming.
