This commit introduces logic for using a new X11 window for each incoming transfer, rather than having a global window for each selection source. This eliminates a whole class of bugs involving multiple concurrent incoming transfers. For now, we retain the outgoing transfer queue, and the selection source-specific windows to support it. Source-specific windows are no longer used in the incoming path, and will be removed in a future PR. Refs #1497.
