Implement startup notification spec again.

This functionality was in Qt4's qapplication_x11.cpp and was missing
from the XCB QPA plugin. Ported the code from xlib to xcb.

This code was actually tested (with plasma), unlike the Qt-4.8 code which
skipped every other character...
    for (uint i = 0; i < 20 && i + sent <= length; i++)
        xevent.xclient.data.b[i] = message[i + sent++];

Provide a QPA native-function for accessing the startup id, for cases where
an application doesn't show a window, but starts another app instead, or asks
a running app to show the window on its behalf.
