avg fbf65ae4d9 syscons: provide a first iteration of cngrab/cnungrab implementation
- put underlying keyboard(s) into the polling mode for the whole
  duration of the grab, instead of the previous behavior of going into
  and out of the polling mode around each polling attempt
- ditto for setting K_XLATE mode and enabling a disabled keyboard
