input: add support for XIAllDevices and XIAllMasterDevices passive grabs.

Browse source 
These grabs are suported through two fake devices inputInfo.all_devices and
inputInfo.all_master_devices. These devices are not part of the device list
and are only initialised for their device id, nothing else.
