replace uninterpreted_data by switch-case
this is needed by request ChangeDeviceControl.
spec:
http://cgit.freedesktop.org/xorg/proto/inputproto/tree/specs/XIproto.txt?id=inputproto-2.3.1#n688
http://cgit.freedesktop.org/xorg/lib/libXi/tree/specs/encoding.xml?id=libXi-1.7.4#n1907
Note: Only the DeviceCtl of type DeviceResolution is defined in both specs.
( this is struct name="DeviceResolutionCtl" in the xml. )
The other DeviceCtls are not defined in any of the specs.
code:
http://cgit.freedesktop.org/xorg/proto/inputproto/tree/XI.h?id=inputproto-2.3.1#n170
http://cgit.freedesktop.org/xorg/proto/inputproto/tree/XIproto.h?id=inputproto-2.3.1#n1343

This requires enhancements to the xml-schema and generator such as union with selector.
This will, e.g., be necessary for automatically generated byte-order conversion code,
which will, e.g., be necessary for server-side xcb.
This affects the following:
* QueryDeviceState reply field "classes" ( structs InputState, ... )
-* ChangeDeviceControl request field "control" ( structs ChangeDeviceControl, ... )
* XIChangeHierarchy request field "changes" ( structs HierarchyChange, ... )
* struct XIDeviceInfo field "classes" ( structs DeviceClass, ... )
* SendExtensionEvent member "events"
*****
xml and generator have to support <popcount> of all members of a list
