emacs: Use general functions instead of generated ones.
* emacs/guix-base.el: Add and use general functions instead of specialized functions generated by 'guix-define-buffer-type' macro. (guix-buffer-type, guix-entry-type): New variables. (guix-set-vars): Add new variables. (guix-get-show-entries, guix-show-entries, guix-set-buffer) (guix-history-call, guix-make-history-item) (guix-get-params-for-receiving, guix-revert-buffer) (guix-redisplay-buffer): New functions. (guix-define-buffer-type): Do not generate specialized functions. * emacs/guix-info.el (guix-package-info-insert-full-names): Use 'guix-get-show-entries'. (guix-generation-info-insert-number): Likewise. * emacs/guix-list.el (guix-list-describe): New function. (guix-list-define-entry-type): Do not generate specialized one. (guix-generation-list-show-packages): Use 'guix-get-show-entries'. * emacs/guix.el (guix-show-generations-function): Remove. (guix-get-show-packages): Use new functions. (guix-get-show-generations): Likewise.
