    Remove generation of core events, long live XI!
    
    Let the drivers only generate XI events and put those into the event queue.
    When processing events, generate core events as needed. This fixes a number of
    problems with XKB and the DIX in general.
    
    The previous approach was to put core events and XI events as separate events
    into the event queue. When being processed, the server had no knowledge of
    them coming from the same device state change. Anything that would then change
    the state of the device accordingly was in danger of changing it twice,
    leading to some funny (i.e. not funny at all) results.
    
    Emulating core events while processing XI events fixes this, there is only one
    path that actually changes the device state now. Although we have to be
    careful when replaying events from synced devices, otherwise we may lose
    events.
    
    Note: XI has precedence over core for passive grabs, but core events are
    delivered to the client first.
    
    This removes the wrapping added in 340911d7243a7f1095d79b5b2dcfa81b145c2474

    mi: switch core keyboard on XI events, not only on core events.
    
    We only get core events through the EQ in exceptional cases, so make sure we
    actually swap the core keymap for XI events as well. Gives us back the ability
    to have multiple keyboard layouts simultaneously.

@uli42: could you have a look at these (see #347) patches from X.org? Could they possibly fix the CAPs lock and and and NUM lock problems (toggle state being out of sync sometimes)?

Any PR for the 1.4.2 patch, yet?
