walker: drop fields of `struct walker` which are always 1

After the previous commit, both users of `struct walker` set `get_tree`, `get_history` and `get_all` to 1. Drop those fields and simplify the walker implementation accordingly. Let's hope that any out-of-tree users will not mind this change. They should notice that the compilation fails as they try to set these fields. (If they do not set them, note that `get_http_walker()` leaves them undefined, so the behavior will have been undefined all the time.)
