spice client: sticky Alt activation when holding an Alt key: bug #505912.

Additional changes that were required for the feature:
    1) focusing on the pointed window in full screen mode
    2) In X11 - handling events that occur during keyboard ungrabbing
    3) In X11 - handling Leave/Enter Notify events that occur during keyboard grabbing/ungrabbing
    4) In X11 - fix for focus events that are handled in the wrong order (happens when
       focus events occur during grabbing the keyboard)
    5) In X11 - ignoring key release events during key holding
    6) In Windows - synchronizing keyboard release events that occured during a modal loop
