(flymake-timer): Move definitions, so we can remove earlier declarations.
(flymake-replace-regexp-in-string, flymake-split-string)
(flymake-get-temp-dir): Use defalias.
(flymake-popup-menu): Remove `pos' argument.  Use posn-at-point.
(flymake-xemacs-window-edges): Remove unused function.
(flymake-get-point-pixel-pos): Move.
(flymake-pid-to-names, flymake-reg-names)
(flymake-get-source-buffer-name, flymake-unreg-names): Remove.
Replace by a simple list flymake-processes and by process-buffer.
Update callers.  Other than simplify the code, it uses buffers rather
than buffer-names so it doesn't get confused by uniquify.
(flymake-buffer-data): The global value should just be nil.
