This is a partial revert of commit d2b299a91f.
* emacs/guix-base.el (guix-revert-buffer): Make it more general by
removing the code specific to a particular search (a search for
packages/outputs by ID). Rename to...
(guix-buffer-revert): ... this.
* emacs/guix-base.el (guix-buffer-after-redisplay-hook): New variable.
(guix-redisplay-buffer): Use it. Remove all arguments and the code
for moving point to the next button. Rename to...
(guix-buffer-redisplay): ... this.
(guix-buffer-redisplay-goto-button): New procedure.
* emacs/guix-info.el (guix-package-info-show-source): Use it. Adjust
accordingly.

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.
* emacs/guix-base.el (guix-define-buffer-type): Rename to...
(guix-buffer-define-interface): ... this. Rename internal
variables ('buf-' -> 'buffer-'). Move ':required' keyword to
'guix-ui-define-interface'.

"E" for '--expose' and "S" for '--share' to distinguish them from
'--expression' and '--system' accordingly. Make '--ad-hoc' an option
