[emacs] rework the configuration for navigation.

mostly inspired by reading https://github.com/patrickt/emacs.  i've
made the configuration of counsel and ivy more explicit, by splitting
the customization.

i've fixed the binding for searching with a buffer to rely on rgrep
instead of ag (since i've switched to rg).

i'm going to try the module 'guide-key' to see if i can be better at
remembering some bindings (i always forget a bunch of them).
