When the keyboard layout is modified via xmodmap, each single "change" (line of input to xmodmap) causes an "the keyboard configuration changed"-event to be sent. Awesome reacted to each of these events by reloading the keyboard layout. Thus, awesome reloaded the keyboard layout a lot and appeared to freeze. Fix this by asynchronously update the keyboard state: When such an event comes in, instead of reloading things immediately, we set a flag which makes us update the state at the end of the main loop iteration. This means that many events still cause only a single (or at least few) re-quering of the layout. Thus, a lot of time is saved. This commit removes the argument to the (undocumented!) signal xkb::group_changed. Previously, the argument was the active group number. Since this argument was unused and I'm lazy, I just removed it. The alternative would be that it might be visible to Lua that some "the active group changed"-events are dropped.
