Daniel Stone 7d2543a3cb XKB: Add debug key actions for grabs & window tree
Add four new private XKB actions for debugging:
    * PrGrbs: print active grabs to the log file
    * Ungrab: ungrab all currently active grabs
    * ClsGrb: kill clients with active grabs
    * PrWins: dump the current window tree to the log file

To use these, you need to modify your XKB maps, e.g. the following to
have Ctrl+Alt+(F9-F12) mapped to the above:
 - compat/xfree86:
    interpret XF86LogGrabInfo {
        action = Private(type=0x86, data="PrGrbs");
    };
    interpret XF86Ungrab {
        action = Private(type=0x86, data="Ungrab");
    }
    interpret XF86ClearGrab {
        action = Private(type=0x86, data="ClsGrb");
    }
    interpret XF86LogWindowTree {
        action = Private(type=0x86, data="PrWins");
    }

 - symbols/pc:
    key <FK09> {        type="CTRL+ALT", [ Return, XF86LogGrabInfo      ]   };
    key <FK10> {        type="CTRL+ALT", [ Return, XF86Ungrab           ]   };
    key <FK11> {        type="CTRL+ALT", [ Return, XF86ClearGrab        ]   };
    key <FK12> {        type="CTRL+ALT", [ Return, XF86LogWindowTree    ]   };

At the moment, this only works if the grabbing client continues to call
AllowEvents, as the server does no event processing at all when a device
is frozen.
