Oliver Schmidt 11bb32e561 hw/xwin: Restore non-latching modifier key state when an X window gains focus ...

In multiwindow mode, the state of the modifier keys was lost when a window is
created (or raised) and focus moved to that window.

For example: In window A Ctrl + some key opens a window B, then in window B Ctrl
+ some other key triggers the next action. However after the opening of window B
the Ctrl key has to be released and pressed again. If the user keeps the Ctrl
key held down when the window B is opened, the next key press X will be
interpreted as X and not as Ctrl+X.

Extended the function winRestoreModeKeyStates in winkeybd.c to consider not only
the latching modifier keys but also the modifiers Ctrl, Shift, Alt/AltGr by
using the Windows function GetAsyncKeyState.

A combined Ctrl+AltGr modifier state cannot be restored correctly, as Windows
always fakes a Ctrl-L when AltGr is pressed.
