+Subject: QClipboard: Fix emitting changed() in XCB
+
+In XCB environment the QClipboard::changed() was not delivered if the
+QClipboard::clear() was issued by other Qt app/process.
+
+If the QClipboard::clear() is used, then the owner in
+xcb_xfixes_selection_notify_event_t is XCB_NONE, so we need make the
+decission to handle this event by the selection_timestamp and our
+m_timestamp[mode].
