Tweak the Flymake diagnostics buffer again

* lisp/progmodes/flymake.el
(flymake-diagnostics-buffer-mode-map): Don't bind [mouse-1].
(flymake-show-diagnostic): Rename from
flymake-show-diagnostic-at-point.  Really use another window.
(flymake-goto-diagnostic): Rename from
flymake-goto-diagnostic-at-point.
(flymake--diagnostics-buffer-entries): Use a button just for
the message bit.
