commands: move checkconflict to bookmarks module

Again, commands.bookmark is getting too large. checkconflict already has
a lot of state and putting it in the bmstore makes more sense than
having it as a closure. This also allows extensions a place to override
this behavior.

While we're here, add a documentation string because, well, we should be
documenting more of our methods.
