Uli Schlachter 9f3a6757e9 Asynchronously update the keyboard state
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.
