(compilation-error-properties): Allow to funcall col and end-col.

(compilation-mode-font-lock-keywords): Check col and end-col by `integerp'.
(compilation-goto-locus): If end-mk is non-nil in transient mark
mode don't activate the mark (and don't display message in
push-mark), but highlight overlay between mk and end-mk.
