Subject: [PATCH] backend-native: Handle keyboard repeat settings

We need to tell clutter's evdev backend about the desktop's key repeat
settings so that our own key bindings event processing and
gnome-shell's chrome widgets get their fake key events for continuous
key press as they expect.

Note that the wayland frontend filters out these events and thus
wayland clients do not see them as specced.
