dbd6e74d3c x11: Let selection input streams create their own window
When there are two (or more) concurrent XConvertSelection requests with
the same target, selection and window and the data is large enough for
SelectionNotify events to overlap. This can result in the affected streams
being considered completed without any data being transferred.

While regular mutter/shell code does not make use of concurrent
XConvertSelection requests with the same targets, some extensions might.
Such as for example a clipboard manager that like the built-in clipboard
manager tries to read the selection on owner-changed.

One potential solution would be to make sure the event is for the correct
property, but not all clients seem to support concurrent requests for the
same targets but different properties on the same window.

This commit instead changes the streams to use their own window which
seems to be more widely supported.

156980eff9 x11: Add X11 selection input/output streams
These are rip off of GTK+ ones, with some adaptions to integrate them in
mutter event dispatching code and make them easier to use in future
commits.
