alter conf_grab(_kbd) to first ungrab AnyKey/AnyModifier, then proceed
to grab keys in keybindingq.  we don't need to ungrab/grab on every
addition to the queue, just once with a complete keybindingq; simplify
grabbing keys per screen (during init) and during a MappingNotify.

while here, change conf_grab_{kbd,mouse} to require only a Window.
