[Xcb] XKB once again

[Thomas Hunger]

Hi, 

XKB requests have the form XkbSomeRequest. E.g.

    <request name="XkbUseExtension" opcode="0">

When this is translated to c it will look like

    xcb_xkb_xkb_use_extension(...)

where the first xkb comes from the "namespacing" (extension-name) and 
the second from the Xkb-prefix of the request.

Do you think I should just leave out the Xkb in the request name? The 
result would be:

    xcb_xkb_use_extension(...)
